With an extensive product range on offer, the Ainsworth Valves team are optimistic about the future.

It was with this in mind that Reggie Naidoo opted to form a new company called Ainsworth Valves. “We brought back some of the old staff members experienced in valve manufacturing as it was clear that we could not lose this host of knowledge,” he says. “Some of the staff have more than 28 years of experience in manufacturing valves. This was a clear opportunity for a new beginning.”

“We want to continue to grow and build the brand, not only locally, but also internationally.”

Trends, challenges and outlook

Moving Ainsworth forward Naidoo says instead of dwelling in the past the company has geared up for a bright future. “The outlook for the business is ready to continue from where the old Ainsworth left off in its glory days,” he says highlighting that the company was renowned for its quality products.

“We carry the RSV water works, RSV green Mamba rubber line gate valve, non-return (reflux) valves, tilting discs nonreturn, high-pressure wedge gate valves, butterfly valves and fire hydrant valves,” explains Naidoo.

Naidoo says it has been challenging because the 70% local content that government requires is not being followed or Thismet.makes it increasingly difficult for local manufacturers to compete with cheap imports.

“We cast and manufacture all of our products locally delivering a product that is price competitive and of very high quality. We are also based locally making it easy to access spares and servicing of our products.”

“It is extremely worrying because we continue to see more and more imported products in the local market despite government requirements for more local content.”

Letting go of all the experience, knowledge and capability seemed to only accentuate the loss to the industry.

In the current fast-changing market, even when you believe that something has had its time, new opportunities pop up almost out of nowhere. This holds true for Ainsworth Valves that have arisen from the ashes – new and improved. Pipes, Pumps and Valves Africa find out more.

Ainsworth Valves, +27 (0)10 020 www.ainsworthvalves.comsales@ainsworthvalves.com,8388,

At the time of its liquidation, Ainsworth Engineering was one of the oldest valve manufacturers in South Africa. The company had built a solid reputation for delivering quality valves to a range of sectors.

According to Naidoo, the strategy is very straightforward.

“We want to bring back the rich history of valve manufacturing that Ainsworth Engineering once had,” he says. “Our goal is to deliver a range of products that can stand the test of time. We are focusing on continuing with the manufacturing of local quality valves on the Ainsworth product portfolio.”

Ongoing research and development also aim to complement the companies’ current offerings. “One of the biggest challenges that we face in South Africa is that of cheap imported valves that simply don’t last as long compared to the quality locally manufactured products.”

Naidoo says with quality casting from one of the best foundries in South Africa Steloy Foundries there is no reason why the set goals cannot be achieved. For Naidoo, the outlook is extremely positive. “We want to bring back alive the 80 years of one of South Africa's oldest valve manufacturing companies and allowing for more growth and prosperity to last another 80 years or more.”

There is also a big demand for valves in the water and wastewater sectors in South Africa and Africa, while power utilities are continuously looking for quality products that meet their needs.

He says the benefits of buying local far outweight the risk of purchasing a cheap import.

He says by offering competitive pricing, service and delivery the brand is set for new heights. “We have plans to grow our local and international footprint as we are known for our quality product and service.”

Integrated Pump Rental, +27 (0) 11 894 www.pumprental.co.zaadmin@pumprental.co.za,2906, There was more to come from the same customer. Just a month later, they called again after detecting further contamination of more dams. Once again, there was no time to lose. Urgent pumping was required to control the risk of contaminated discharge.

“This time, the need was for four high head Sykes XH150 rental pumps,” says Strydom. “They were delivered on the same day, with 2,800 m of lay-flat hose with clamps and straight connectors.”

The Sykes XH150 dewatering pumps, offering a maximum head of 170 m with a maximum flow rate of 140 litres per second and capable of handling solids with particle sizes of up to 43 mm, were more than suitable for the task.

“The Sykes XH150 pump offers automatic priming and solids handling capability,” he says. “It also has one of the best shaft stiffness ratios of any automatic priming pump on the market.”

Time was of the essence, as these pumps had to provide four bypass water lines for a contaminated water source which could not be released into the river system. The four Sykes pumps easily maintained a constant flow rate of 190 m³ per hour over a distance of 700 m. They ran on a 24-hour basis to ensure a constant water flow through the four Strydompipelines.saysthe

Sykes CP150 dewatering pumps were ideal for the job. They offer a maximum head of 60 m with a flow rate of 172 litres per second. It is also capable of handling solids with particle sizes of up to 77 mm.

A quick response recently saved the day for an IPR customer, who needed an urgent contaminated water bypass.

Each of these Sykes extra high head pumps delivered a flow of 220 mᵌ/h over 1,200 m. He highlights that the pumps can be primed with long suction hoses and can manage suction lifts of up to nine metres.

The robust construction of the pumps ensures optimum reliability and long life. Importantly, they can run dry for extended periods of time without damage. The pumps also boast low fuel usage and lower maintenance costs, and can operate in ‘snore’ conditions.

“The Sykes CP models – or the contractors’ range –are designed to meet the heavy duty demands of the construction, mining and rental industries,” he says. “With pump efficiencies up to 83%, they provide faster and more efficient pumping, resulting in savings to the end user.”

“We immediately sent a pump rental quote following the customer’s call, and specified four Sykes CP150 medium head dewatering pumps,” says Andre Strydom, rental development manager at IPR. “These were delivered and commissioned on site the next day, with 1,500 m of 150 mm lay-flat hose and all other necessary equipment.”

The large fuel tanks on the Sykes range of dewatering pumps facilitate continuous pumping for more than 24 hours, which according to Strydom makes refuelling that much easier as this only needs to be done once in a 24 hour cycle.

IPR to the rescue in water contamination emergency

“The Sykes CP150 units also feature sophisticated automatic priming capabilities,” he says. “These are based on a Venturi system that can deliver suction lifts of up to nine metres.”

With the growing concern about rapidly increasing energy costs due to world events and climate change, many industries are focused on reducing energy costs. For a factory manager, reducing overall costs at a production facility is of paramount importance. This is especially true of industries that intensively use vacuum applications. In most modern industrial production facilities vacuum applications are the most used utility. Moreover, the fact is vacuum applications are also one of the largest consumers of energy.

To keep it simple, for Atlas Copco Vacuum energy efficiency means doing more or achieving more with less. There are two ways to approach this; either a machine is energy efficient when it delivers the same performance using lesser energy or a machine works better than before with the same amount of energy. Is there a newer way to analyze and measure energy efficiency? How does an energy efficient product affect the production and operational efficiency of the entire production line or even the entire factory?

The need for energy efficiency in modern industry

10 Pipes, Pumps and Valves Africa - Jul/Aug 2022 PUMPS

Given this reality, energy efficiency associated with the vacuum applications production chain has a significant impact on both power utility costs and the environment. One answer is the use of renewable energy sources and Thetechnologies.moreimmediate way to reduced environmental impact is improved energy efficiency. For any industrial application or production facility there are ways to lower their carbon footprint and improve energy efficiency.

How does Atlas Copco Vacuum define energy efficiency? Atlas Copco is an industrial vacuum pump manufacturer, that develops vacuum pumps that run efficiently because we understand the needs of the industries we serve. Whatever the application, we provide suitable vacuum pumps, solutions and service. As a leading innovator in the industrial vacuum pump market, we have a continued focus on vacuum pump efficiency that translates into energy and running cost savings for our customers. Our vacuum pump technology is the starting point in providing a total vacuum solution for dedicated point-of-use machines and central vacuum systems.

With HEX@ you can monitor and control your pump from anywhere and at any time. You can receive feedback and review pump operating status, vacuum levels and upcoming scheduled events for your vacuum system.

Setpoint control to optimize your process and save energy Atlas Copco variable speed vacuum pumps have opened opportunities to save energy by way of process optimization. Possibly the most significant of this is the concept of setpoint control. By allowing your factory manager or process engineer to define the operating pressure at a precise level and then modify that setting even after the vacuum system is installed, significant savings can be achieved.

Weir Minerals integrates key brands in mudflow™ pump

The cutters mechanically agitate the settled solids, allowing abrasive and highly charged slurries and mud to be efficiently pumped. He emphasises that the components making up the Multiflo® Mudflo™ pump are drawn from Weir Minerals proven brands, and are carefully combined to produce an integrated solution that saves customers time and money. It also reduces environmental impact, by avoiding the costly and energy-intensive process excavating and trucking the material off site.

“The pump design includes Weir Minerals' Ultrachrome A05 chrome alloy casting for high wear resistance,” he says. “There is also a suction strainer to prevent excessively large particles clogging the pump.” This ensures that the unit delivers optimal uptime alongside high performance levels: the Mudflo™ 200 pump is capable of pumping between 150 m3/h and 1,200 m3/h, up to a head of 82 metres. The pump can handle a maximum particle size of 80 mm, and a maximum liquid temperature of 35°C.

“While our integration of products has grown organically over the years, it has become more systematic and deliberate as our product range has grown and become more diverse,” says Koorts. “The way we have developed this solution shows the progress in recent years toward integrating our product lines to add value to our offerings.”

He notes that the process of ETO ensures that solutions developed by Weir Minerals’ engineering teams deliver more value than the sum of their component parts. In this case, the company’s dewatering experts were able to draw on the best technology from Weir Minerals’ Multiflo®, Warman® and Weir ESCO® brands – combining them with advanced hydraulics to create an innovative result.

“Our extensive footprint in the field and our close collaboration with customers on a daily basis gives us a detailed understanding of their specific requirements,” he “Wesays. can therefore ensure that our innovations are fit for purpose, being based on our considerable ETO capability and technical excellence.”

Integrated solutions are what separates equipment suppliers from solution providers, argues Marnus Koorts, general manager pump products at Weir Minerals Africa – and the recently launched Multiflo® Mudflo™ pump shows how this is done.

“The Multiflo Mudflo pump successfully combines elements of the Warman MGS submersible slurry pumpend, and a custom Multiflo designed bearing assembly coupled to a hydraulic motor,” he says. “Another key ingredient is the pairing of twin Multiflo CB33 hydraulic cutters with Weir ESCO excavation teeth.”

This dredge/excavator-mounted, mud-pumping innovation was launched last year, after being developed in response to a challenge which a customer faced, says Koorts. It is a heavy duty hydraulic submersible slurry pump designed for abrasive applications and large particle handling. Its application is primarily in reprocessing and relocating tailings ponds, maintaining water retention dams and managing slimes and sludge ponds.

As developments took place industry moved wards failure and reliability statistics on many assets instead of introducing a reliability-centred maintenance approach that allowed for maintenance to be planned somewhat better and for costs to be controlled. “The system still was not perfect and we saw the development of conditionbased maintenance. This is where monitoring, data analysis and diagnostics came into play along with the ability to determine when the equipment would fail.’

before, businesses are investing heavily in digital tools and technologies that help them leverage data to generate valuable insights. In the manufacturing world, predictive maintenance (PdM) is at the forefront of this technology movement and represents the strongest solution to the persistent manufacturing challenge of unplanned downtime. Pipes, Pumps and Valves Africa find out more. Technology solutions are usually introduced for two reasons – to improve productivity and to impact positively on profitability. Many companies, however, still struggle to realise the full value of these solutions, says Bharat Vats, Chief Revenue Officer at Novity. He says it is important to understand that not all PdM solutions are created equal and several factors need to be considered when introducing these solutions into an Hisoperation.advice is to look for a solution that is firstly highly accurate. “Predictions that are often 90% and more than three months ahead of a failure, even when little failure data exists, is what you should be looking for. Just as important is always-on, real-time decision support that informs users when a piece of critical equipment will fail thus reducing unplanned downtime and its negative Theconsequences.”biggestbenefit of a PdM is that these solutions allow operations teams to focus on meeting production goals and not be focused on large-scale data management and maintenance regimes. “Over the past five decades there has been an evolution of maintenance programmes,” he says. “It started with interval-based maintenance practices where maintenance was scheduled based on the breakdown of equipment. This was highly uncertain and came with significant costs.”

“The problem, however, was that the operation team still did not know why it was failing, when it would happen again or where the cause was.” This, says Vats, is where PdM’s are making a difference.

“Industry 4.0 has moved the industry from a vision to reality. With predictive analytics, prognostics and the like, prescriptive maintenance can now take place,” he says. “Digitization is enabling more efficient plant operations than ever before. Plant operators are using

He says it is easy to understand why PdM is gaining popularity around the world because from a business standpoint it made financial sense thanks to the very high return on investment.

Using a case study at an international chemical plant as an example he said unplanned downtime was costing the company around $5 million per year – sometimes even more.

“The best advice is to do your homework. The other important piece of advice is to choose a technology provider that you can build a partnership with and can work closely together.There are no shortcuts if you want to do this well.”

“Not every operation needs a PdM. The first step is therefore to evaluate your needs and your operation and determine what solution will do the job and secondly, look at what technology is the right fit for your company and your Heemployees.”saysstaff must be trained and understand the technology before it is brought on board. Policies and processes also need to be in place.

Excessive inventory costs drove up the cost even more coming in at $4 million. “This was because the plant was obligated to hold an excessive spare parts inventory at the plant to address the number of breakdowns,” explains Vats. These costs were all addressed with the introduction of PdM. “Studies have shown that up to 40% of maintenance work is unnecessary. Knowing ahead of time which inspections will yield effective work orders radically increases efficiency. The chemical company saw a massive drop in its inventory costs and reduced downtime significantly.”

Understanding PdM According to Vats, predictive maintenance entails monitoring key equipment properties to detect changes or trends that serve as early indications of conditions which need to be addressed.

Pipes, Pumps and Valves Africa - Jul/Aug 2022 17 PUMPSPUMPS CY Pumps, pipes and valves Africa May 2021.pdf 1 2021/04/28 15:36:21

“The bleeding rate was so high and they were struggling to plug it as they had no idea where it was coming from. They only knew the equipment was failing and the plant was coming to a standstill.”

Benefits of PdM According to Vats, a more efficient maintenance schedule is, however, only one of several benefits.

“A successful PdM deployment requires a detailed understanding of production processes, infrastructure, data availability and quality, maintenance models and processes, policies and equipment failure modes,” he says.

these new digital technologies across a wide variety of applications making asset performance management a reality. It is an ongoing journey and we are by far not completely there as yet as an industry. Predictive maintenance is still evolving.”

Higher uptime and productivity, fewer re-active maintenance actions and lower inventory costs are all part and parcel of it. “With PdM, one is no longer hurting the production goals that are being positively impacted by higher uptime availability while operators have enough confidence to hold fewer spares thus reducing overall inventory costs.”

“There are two key parameters to consider. Firstly, can one have amortization in less than 12 months and is it a positive Return on Investment (ROI).”

Instead of trying to fix catastrophic pump failures operators are using PdM to choose not only when and why shutdowns occur but to determine the root causes of This,failures.inturn, minimizes the impact shutdowns have on efficiency and the bottom line.

“In most cases, we are seeing that at least 45% of operators are reporting amortization in less than a year (in most cases it is less than 11 months) and at least 83% of surveyed companies have reported positive returns on investment.” Vats advise that it is important to consider one’s operation carefully, however, before investing.

Integrated Pump Technology plans expanding Southern African ParticipationfootprintatElectra

Mining Africa 2022 will serve to underpin Integrated Pump Technology’s drive to increase its footprint in Africa. According to general manager, Jordan Marsh in the less than 10 years since the company secured the Grindex pump distributorship for southern Africa it has already significantly increased the product’s installed footprint in South Africa and made good inroads in southern Africa.

Marsh says this can be attributed to a number of reasons, chief among which is the strategically situated distributor network which Integrated Pump Technology maintains in South Africa, and it is this successful operating model that will be further extended beyond its existing African distributor base in the coming months.

“Distributors are a critical link for us, more often than not forming a solid relationship and logistical chain between ourselves and the end-user. These partners are carefully selected, and we maintain extremely strong relationships with them to ensure customers are assured of technical competence from before the purchasing decision is made, with quality after-market support provided for the full lifecycle of a product,” Marsh continues.

“There is a large installed base of Grindex pumps in Africa with the brand well-recognised and we have been looking at individual regions and country demands as well as available partners to ensure that we have a distributor in place with the requisite depth of knowledge of that particular country’s market requirements, can speak the local language and also has the necessary technical Integratedbackground.”Pump Technology recently appointed new distributors in Zambia and in the DRC, which the company considers to be vital markets for the dewatering solutions

Strengthening its distributor footprint in Africa will give ready access to both product and support to existing and potentially new customers in the regions served by Integrated Pump Technology which include all countries bordered by South Africa as well as Zambia and the DRC.

Commenting on the rational behind the injection of capital, Marsh says that in recent months there has been a demand for certain Grindex pumps which impacted on lead times and the company made the decision to invest in more stock to meet the growing demand. It goes without saying that the parts stockholding has also been increased to ensure the same level of access for distributors and customers.

“When extending our distributor footprint, it is essential that end-users be able to access the level of technical support that our customer in South Africa can,” he says. Unpacking what Integrated Pump Technology means by technical support, Marsh explains that competent product engineers and service personnel from the company are assigned to support individual distributors. These individuals, who are a dedicated resource to a distributor, have the ability to assess any given dewatering application and propose the best fit solution for the enduser. In addition, we bolster the technical competence of distributor personnel by proving ongoing upskilling and product training.

Unfortunately, life is rarely this easy, hence why there are many types of pumps.

The duty/service class is also used to provide recommended limits for other calculations such as stage pumping and impeller tip speeds.

Slurry pump selection – Choosing the right solution for your duty

The importance of data can easily be overlooked especially with a pump that is already installed and has been running on its calculated duty point for some time. As sites develop, it is normal for duty points to change

When looking at a new pump installation, it is all about the data. In an ideal world we would have one pump for all duties, making life easy for suppliers and operators alike.

The importance of data

Read on in this blog as we discuss about selection criteria and considerations when selecting the optimal pump for your operation. As a minimum, it is normally required to have both the flow and head of the duty. This will allow for a very basic selection using the available pump curves. It is worth keeping in mind that published curves from manufacturers are based on clean Thiswater.is due to the many various slurries that are available, which would require manufacturers to supply thousands of curves and would not be feasible. This is where manufacturer pump sizing tools come in handy, such as the Metso Outotec PumpDim™ tool, which takes the supplied slurry data and system information to provide an adjusted ‘slurry curve’. This results in the tool providing an optimal pump recommendation for the operation. However, no matter how good a calculation tool is, the result is dependent on the data that is provided. The saying, “Rubbish in means rubbish out,’ is very relevant here. Depending on the abrasiveness of the application, pumps have a sweet spot in which they like to work. This is called the preferred operating range, which is a percentage of the best efficiency point (BEP). The more abrasive the application, the smaller this sweet spot becomes. To simplify things, these ranges are organized into service classes as determined by the Hydraulics Institute and uses the average particle size (d50) and the slurry specific gravity. Starting at Service Class 1, which is essentially a water duty, and making its way up to the very highly abrasive Service Class 4, which would be like a Mill Discharge application. Using these service classes, we can determine the correct pump to be used along with ensuring the speed of the pump is also correct.

22 Pipes, Pumps and Valves Africa - Jul/Aug 2022 PUMPS

An increase in flow may not be considered a major factor on some equipment, but when it comes to a pump it can push its operation from the most efficient point toward a critical range.

It is well known in the industry that slurry pumps will not be able to run forever due to the nature of its work.

But every mine aims to extend this life as much as possible, which happens by being as close to BEP as Smallpossible.adjustments in flow or head can move the duty point on the curve considerably has and have implications on wear life. Moving further to the left of BEP, usually due to a reduction of flow or head, creating recirculation in the pump meaning the material travels around the casing excessively before it is moved down the line. This creates additional wear due to the extra circulation of particles. Alternatively, the duty point can be pushed to the right of BEP by increasing the flow. This can cause issues with inlet velocity meaning the flow into the pump is greater than the installed size that the pump can Andmanage.resulting in increased wear rate around the discharge area of the casing and on the eye of the impeller, which is the first obstruction the flow finds when entering the pump.

In some of these cases a pump can be adjusted on speed to help deal with the changes of duty, but in other cases it would be recommended to change the pump size to best fit the altered Withoutapplication.takingthese changes into

consideration, a previously well performing pump can turn into a maintenance headache.

There are other factors that can have detrimental impacts such as changes in the feed material and installation alterations to pipework like lengths, dimensions, and others. This can result in an increase in friction losses in the system. The reason pumps like to work at its most efficient point is because this reduces the amount of wear seen, ultimately extending the service life.

Another factor to keep in mind is that as a pump wears and moves away from its optimum point it has a reflective effect on the power

IPR to showcase its pump dewatering & dredging offering at Electra Mining

Fast-growing pump dewatering and dredging specialist IPR (previously Integrated Pump Rental) has ambitious plans for this year’s Electra Mining Africa, reflecting the importance the company – which derives most of its turnover from the mining industry – attaches to the show.

“IPR is a young company, having been established just seven years ago, but we’re growing very rapidly and have tripled our rental fleet since late 2021,” says company founder and MD, Lee Vine. “We attribute our growth to the excellence of our service but Electra Mining Africa has also played a role. Since we started up, we’ve been at every Electra Mining Africa held and the results – measured in terms of new business – have been Basedphenomenal.”inJetPark, Johannesburg, IPR operates an extensive rental fleet consisting of approximately 210 pumps, mostly diesel-driven, able to take on virtually any pumping task.

IPR’s business is not confined to rental and all the units in its fleet can also be purchased. The company is the sole agent in southern Africa for the globally recognised Sykes range of diesel-driven dewatering pump sets and is also able to supply other brands such as Grindex, Flygt, Godwin and Atlas Copco.

“While our business has been built on selling and rentingout Sykes pumps, we are not wedded to a single brand and can accommodate customers who have a preference for pumps from other manufacturers,” says Vine. Although IPR derives the bulk of its turnover from the South African market, the company has provided

As always, IPR will have its technical experts, including Vine himself, on hand to engage with visitors and pass on the company’s core message –that it is a solutions provider. “We offer a highly personalised service to customers,” says Vine. “In respect of our rental business, we don’t simply drop off a machine on site and disappear.”

“This is the biggest unit in our rental fleet,” notes Vine. “It is a self-priming pump which can run dry for extended periods. Features include low fuel usage and low maintenance costs.”

With its stand located adjacent to the pond at the Expo Centre site, IPR will also have its SlurrySucker and SlurryBlaster units operating on the water and is planning some hydro mining demonstrations using the SlurryBlaster, which have been a big drawcard at previous shows.

“Having a permanent presence in Zambia, however, will make it possible to provide rental solutions to customers operating both on the Zambian Copperbelt and in the neighbouring DRC.”

According to Vine, visitors to IPR’s Electra Mining Africa stand will be able to see a wide range of running diesel pumps including the new Himax HH220i from Sykes, which is capable of pumping at 220 litres per second against a head of 110 m.

“We are keen to expand our rental footprint on the continent although this is by no means an easy task given the ‘red tape’ involved in taking machines across borders,” says Vine.

The SlurrySucker and SlurryBlaster are designed respectively for dredging silted-up ponds and for removing the accumulation of slurry and sediments on dam walls and inside dams.

“Our goal is to make pumping as problem-free as possible and I believe our track record demonstrates that we’ve achieved this objective.”

He points out that IPR has full engineering capabilities in-house, which allows it to produce fully customised pump sets and provide any associated infrastructure necessary. “For example, if you want your pump to float, we’ll make it float; if you want a walkway, we can also do that,” he says. Looking ahead, Vine foresees continued robust growth for IPR’s rental business.

The recent announcement by the Nakuru County government that Gilgil and Molo towns will be promoted to municipalities is both welcome and timely. Elevation of the two towns is important because it reflects that their populations have risen to the point that they must now be awarded municipality status.

Even more important is the fact that, once water and sewerage infrastructure is up and running, municipalities often see reduced cases of water borne diseases associated with pollution of water resources. Water quality improves because there is reduced pollution of natural river systems. Furthermore, such investments trigger the development of modern infrastructure including residential, commercial, retail, and industrial properties.

The light nature of Weholite technology also makes it easy to use in heavily built-up areas with minimal disruptions to communities, a lack of which has been a challenge for large infrastructure projects.

Employing the local labour force also allows technological and knowledge transfer through training and upskilling. This will further benefit the local communities when future construction projects in these towns are implemented.

As the urban planners begin working on how to implement the water and sewerage infrastructure that these two towns now deserve, it will be in the best interest of citizens for them to make long-term investments that are sustainable. This will ensure that governments do not have to redo projects every couple of years, which is essentially a waste of taxes and disruption to service delivery.

With this elevation, the county government can increase the funding necessary to give their residents a higher quality of service delivery.

One way this goal can be achieved is by using modern building technology like Weholite HDPE pipes, who offers a service life of over 100 years and has extremely low maintenance costs.

Nakuru and other county governments that are elevating towns to municipalities, should be proactive in adopting modern technologies such as Weholite HDPE, as these have proven to offer durable and sustainable solutions to today’s water and sewerage challenges.

Allied Valve Specialists (AVS) is a proudly South African supplier to the valve industry, officially launched in September 2022. AVS brings together two significant players in the local valve market, Steam and Valve Specialists (SVS) and Entrade Valve and Engineering Supplies, under a single brand to operationally leverage 40+ years industry experience. Enhancing operational efficiencies, customer relationships and driving customer value through world-class quality products were the key drivers behind this move.

After surveying 100 key customers across both businesses, it was clear that key strengths were product offering, product knowledge and application advice, and aftersales service The biggest opportunity for future business growth? Innovation In a traditionally conservative industry, the challenge is to define where innovation is relevant, realistic and will lead to tangible customer benefits It’s also important to note that innovation refers not only to technological innovation such as integrating IoT technology into products to assist with real time monitoring and reporting, but also to innovating the way AVS does business. says Tina, “then defined what those meant in terms of innovating our business management structures, supplier and customer relationship management, customer touch points such as our digital presence, all the way through to how we managed and developed our human capital ”

We started with our three key values, CARE, PRIDE & TRUST

From a supplier perspective, AVS has developed strategic partnerships with global leaders including ARI-Armaturen and Hunt & Mitton Securing certified supplier status with these partners has tangible benefits for AVS customers

Merging Tradition & Innovatio

At the start of the alignment process, Tina Angelos, Managing Director of AVS, wanted a view of the areas SVS and Entrade excelled in order to identify opportunities for improvement

By combining the deep, traditional values of a family-owned business with world leading strategic alliances and the integration of digital platforms and CRM systems driving operational excellence and unmatched customer service, AVS is perfectly placed to take a leadership role in the South African valve industry as the go-to valve specialists. our specialist team Cape Johannesburg:

In speaking about what TRUST means for AVS, Tina says it is driven by a passion for developing and nurturing long term relationships with customers, suppliers and internally with the AVS team “Operationally it means we deliver on time, in time, every time Our prices are consistent and we deliver on our commitments to customers and our own team members

Having these strategic partnerships in place is part of our ‘PRIDE, which for AVS in essence, represents humility It’s about taking the time to fundamentally understand our customers and the challenges they face It’s about listening and fulfilling human needs and not simply pushing a product.

Significantly, AVS can facilitate direct access between their customers and product knowledge and technical training specialists at ARI Armaturen, as an example The value of this customers which includes some of South Africa’s biggest boiler manufacturers, is to deliver the best quality product and service at the right time for the correct application

When asked about CARE Tina responds, “the word CARE is a powerful word When I was looking at the AVS ‘why’, I kept coming back to the fact that all the work we do is because we care about our customers That's why we go out of our way to service them and proactively negotiate with customs to release goods CARE is why we exist and come to work. Our staff don’t just ‘come to a job.’ It’s place we love to be and that makes me extremely proud of my team.”

Sulzer brings extended PLR slurry pump series to the market

The specific design combined with a wide range of options makes the PLR pump suitable for highly demanding applications such as abrasive and corrosive slurries, ammonium nitrate as well as froth pumping and selfregulating applications.

As response to the growing demand in the slurry pumping market, Sulzer has extended the PLR slurry pump range. Eight new sizes have been added, extending the capacity up to 3’900 m3/h. The additional sizes come with new features like a removable suction plate and floating flanges.

“A useful rule of thumb is to look at the age of the pumps in your existing arrangement – and if they are older than six or seven years, then an upgrade invariably makes perfect financial sense,” she says. “Where the capital outlay can be recouped in three years or less, it is usually an easy decision to make.”

“With services like our Energy Check and our Energy Audit, we can help key personnel to achieve their KPIs in relation to energy consumption,” she concludes.

Where data is more difficult to gather – for instance, where nameplates have been removed or are not legible – Grundfos can also conduct a more intensive Pump Audit.

Energy costs continue to rise and the pressure is on for the private sector to create a more sustainable, low-carbon economy; what better time for companies to optimise energy usage on their water pumps?

This intervention is of particular interest to the head of engineering in a plant or facilities manager in a building, whose key performance indicators (KPIs) are often linked to the cost-effectiveness of their operations – as well as the carbon emissions generated.

“This will log data for five to seven days, to create a detailed load profile for the customer,” she said. “An added benefit is that the cost of this audit is deducted should they decide to go ahead with our Grundfos solution.”

Energy efficient water pumps save costs and planet

Using a range of equipment from a specialised audit kit, the service engineer will install flow meters and pressure transducers, and measure kilowatt ratings of pumps.

36 Pipes, Pumps and Valves Africa - Jul/Aug 2022 PUMPS

“From this data, we produce an analytical report that shows where improvements can be made,” she says.

Doing this requires firstly a clear picture of a company’s current energy costs, says Gomes, so Grundfos offers an ‘Energy Check’ service to help establish the foundation for a considered solution. This involves a service engineer visiting the site and collecting data from pumps and motors, as well as basic energy consumption indicators.

The information contained in these reports also includes the new system’s lifecycle costs and its return on investment (ROI). She highlights that some customers’ energy savings have paid off the new equipment in less than two years, after which the system provides ongoing and substantial savings in operational costs.

“Original equipment manufacturers like Grundfos have been working hard for many years to make our pumps more energy efficient,” says Nicolette Gomes, senior service sales specialist at Grundfos. “I am still surprised that few pump users take advantage of the opportunity to improve their bottom line by cutting energy costs – at the same time reducing their carbon footprint.”

“Knowing exactly what our energy-efficient Grundfos systems can achieve, we can compare these expectations to the current situation; in our experience, the savings can be up to 30%.”

A swing check valve consists of a disk that swings on a hinged pivot to allow flow in one direction and swings onto a seat to prevent flow in the other direction. The weight

• To prevent the reverse flow of fluid that can damage the equipment upstream.

• To ensure the vacuum is maintained.

The versatility of check valves

The operating principle of a check valve is quite simple: the valve’s inlet side requires a higher pressure than the outlet side for the valve to open. A minimum pressure differential determines at which point the fluid can start to flow (as the valve opens). This pressure difference is known as cracking pressure, also known as the unseating head or opening pressure.

Double door (dual disc) check valves

Lift check valves are recommended in processes with high flow velocities such as steam, air, gas, ovapouror lines

For the check valve to close with no visible leakages, the inlet and the outlet sides will require a pressure differential between them, known as the reseal pressure. Reseal pressure is also known as sealing pressure, sealing head, or closing pressure. In some check valves, the closing mechanism requires a back pressure to seat at the outlet side to prevent flow.

The sealing mechanism’s resistance force and area, typically a spring attached to a valve closing mechanism, determines the cracking pressure.

• To prevent fluids from mixing. There are many different types of check valves, each with its unique mechanisms that determine the kind of process or application for their use. Below is a comprehensive list of check valve types and their functional description. Ball check valves

There is a preference for ball check valves in processes that require no supervision as they require very little maintenance. They are com-mon in spray devices, manual air pumps, refill refillable using syringes, pumping stations etc.

When you combine the functions of a lift check valve and a globe valve, you get the stop check valve. The stop check valve has a handle that can be connected to an actuator and a stem that limits the disk’s movement. The stem is not connected to the disk. The actuator handle rotates to either prevent the flow of fluid through the valve or limit the flow by con-straining the disk travel distance. The piston check valve has the same characteristics as the lift check valve. Functionally, the main difference is the mechanism for closing the valve – a spring-loaded piston in a cylinder. The cylinder guides the movement of the piston up and down during operation. Applications are to the lift check valve recommended in processes with high flow velocities such as steam, air, gas, or vapour lines

Swing check valve

A check valve – also known as a non-return valve or a one-way valve – allows the flow of fluid in only one direction. The entry and exit ports of a check valve are predefined.

Unlike most valves, installation is only possible in one flow direction.

Check valves are quite simple, inexpensive, and can operate automatically without any manual or external control. That’s why they can be found in numerous different apply applications generally, the following are the uses of check valves:

A ball check valve has a ball as the closing part. Typically, the ball is attached to a compression spring, with the ball facing the direction of flow. In other types of ball check valves, there is no spring. A check valve without a spring requires a reverse flow to close. The ball check valve body is conically shaped to guide the ball to the seating position to ensure a positive seal. The operation of a ball check valve is simple. They are often relatively small and cheap. The balls are made of metal or other materials, in exceptional cases where durability or inert conditions are required.

In the double door check valve, two disks that open like a door, allow fluid flow. The disks are attached to torsion springs, which keep the disks closed to prevent the flow of fluid. Double door check valves are low weight, require less space, and are easy to install. They are used with clean fluids in the petrochemical industry, gas liquefaction, HVAC applications, refineries, and other process industries because they are cost-efficient and require low maintenance. Generally, they must be compressed between two flanges. The lift check valve has a similar design to a globe valve. This check valve uses gravity or a higher pressure at the valve’s outlet to return the valve to the seat position and prevent reverse flow. Some types of lift check valves use a spring-loaded disk. Lift check valves can be installed horizontally, vertically, or at an angle. The flow enters the check valve from below the seat and lifts the disk positioned between two guides.

A wafer check valve is quite similar to a swing check valve. It is simple in design and can be used in tight spaces. The main difference is that they are constrained by flanges that hold them in place.

The evolving hydrogen industry today, hydrogen (H2) is primarily used for the production of nitrogen fertilisers or while cracking hydrocarbons in oil refineries. Hydrogen plays an equally important role in the production of synthetic fuels. Gas, coal or biomass are used for this as primary energy. In the future, hydrogen alimented fuel cells as an environmentally friendly energy converter will become more and more important in electric mobility. Moreover, hydrogen will prevail as a future energy carrier for transport vehicles. As the world looks towards decarbonisation of the energy sector, hydrogen – and especially ‘green hydrogen’ produced without emitting any carbon di-oxide (CO2) – will come increasingly to the fore as an energy carrier. For example, water electrolysis is al-ready proven in pilot projects and now so advanced that “CO2-neutral hydrogen” can be produced from entirely renewable energy in large quantities. However, in order to balance an increasing production capacity with fluctuating demand, enormous hydrogen storage facilities will become necessary. For this purpose, gaseous hydrogen is cooled down to minus 253 °C, condensed in liquid form and kept in liquid gas stores.

Safe, 4-offset butterfly valves hydrogen

• Hydrogen is colourless, odourless and tasteless, and depending on the relevant concentration, can be flammable or even explosive in ambient air. Note also that gaseous hydrogen cannot be perceived with human senses.

• The enthalpy of combustion, namely the measure of energy in the thermodynamic process, is lower with hydrogen in comparison with many hydrocarbons. Put another way, hydrogen has a lower volume-related energy density than natural gas. So to store the same amount of energy, a hydrogen tank needs to be three times as large as a natural gas tank. Or the hydrogen has to be stored at three times the pressure.

The role high-quality butterfly valves can play in the energy system transformation and what particular challenges hydrogen places on industrial valves. With the latest United Nations scientific report causing shockwaves around the world, there is increasing urgency to expand renewable energy sources and to embrace new energy carriers.

• The density of gaseous hydrogen is merely 0.09 kg/m3 making it the element with the lowest density. Consequently, hydrogen diffuses relatively easily through a variety of materials. High temperatures and high operating pressures reinforce the danger of diffusion. Steels with a high carbon content are therefore not suitable for this medium, because hydrogen causes the material to become brittle, with the components thereby losing their strength.

• Liquefaction of hydrogen at atmospheric pressure requires a temperature of minus 253 °C as opposed to LNG with ‘only’ minus 162 °C. Liquid hydrogen weighs only 0.071 kg per litre. For clarification: liquefied natural gas (LNG) weighs approximately 0.41 kg to 0.5 kg per litre and is thus 5.8 times to 7 times denser than hydrogen. So challenges for manufacturers of tanks and valves includes using sustainable materials that are compatible with hydrogen and also adapting sealing systems given hydrogen’s propensity to diffuse. This is not an easy task considering that there is a temperature fluctuation of more than 300 °C between the liquid state when storing

The valve challenge In order to assess which check and control valves are suitable for application with hydrogen, certain criteria have to be observed. That is because due to its chemical and physical properties, the handling of hydrogen differs substantially from other energy carriers such as liquid gas (LPG) or liquid natural gas (LNG):

The most promising and currently undisputed energy carriers of the future include hydrogen. This article considers The evolving hydrogen industry

The track record includes applications at extreme tem-peratures from minus 270 °C to 800 °C. Apart from Linde and Air Liquide, references include notable users in the space sector. Their applications are very demanding with enormous demands placed on quality and safety. The fuels consist of liquid hydrogen plus other chemicals.

The valve solution As a valve manufacturer with wide experience of demanding applications, Quadax® has naturally focussed much attention on the topic of hydrogen. Key challenges include the need to operate valves at high pressures (up to 100 bar) and low storage temperatures (liquid hydrogen at minus 253 °C.) To ensure absolute tightness under such conditions, the company has applied its so-called 4-offset design principle (Figure 1). With this design, the butterfly valve benefits from a circular seat with an equal wall thick-ness all around. Hence the 4-offset design is significantly different from the common 3-offset versions which have an elliptical seat (Figure 1).

hydrogen in cryogenic conditions of minus 253 °C up to a transport or gaseous distribution temperature of up to +50 °C.

Actually, dimensional changes in the material caused by high temperature fluctuations act homogenously on the entire sealing surface and thus ensure optimal tightness. This was recently proven in a performance test with helium by an independent testing institute (details available from the authors). What is more, Quadax’s hydrogen valve is equipped with a special seal ring in a special material in order to properly function even at these extremely low temperatures. Since the disc moves smoothly into the seat, wear and tear is significantly reduced. Materials are selected with a nickel content from 10 to 30 per cent. In contact with hydrogen, these alloys show only very little brittleness and the components do not lose any strength. For extreme operating conditions Thanks to the 4-offset design and the latest production technology, the 4-offset valves meet extremely high sealing requirements according to common standards.

This is according to the maker, Vesconite Bearings, which informs that the bearing and wear material has been approved by the Water Regulations Approval Scheme (WRAS). WRAS is an independent UK certification body for plumbing products and materials. It informed Vesconite that Hitemp 160 has passed the full test of effect on water quality. The bearing material is advertised as being able to be used in the high temperature range up to 160 - 200ºC depending on the chemicals in the solution.

With the certification, the material is certified as safe for water intended for human consumption up until "UK65ºC.pump and potable water component manufacturers can confidently use the product within the given temperature parameters,” says Vesconite Bearings CEO Dr Jean-Patrick Leger. The certification also provides comfort for the general safety of the bearing material where it is used outside of the UK, he notes.

Thickener, as the name implies, adds density to the grease. Some greases are thick and tacky whilst others are almost oil-like in consistency. All grease conforms to the international grading standard, NLGI (National Lubrication Grease Institute) consistency class, starting at 000 (thinnest), up 6 (thickest).

The cost of lubrication products (oil or grease) is regrettably often disregarded as they are categorised as consumable products together with cleaning equipment and fluids. Even a small plant can consume as much as 80 tons of grease per annum. On bigger plants lubrication spend can easily run into the millions and if correct lubrication methods are not followed, wastage and related costs remain undetected. So there is enormous potential for savings here by simply applying best practices and controlling grease consumption. Smart lubrication procurement and utilisation can significantly reduce costs; in some cases as much as 50%!

Once the correct grease has been identified, the next consideration is how much grease should be in a bearing. As already mentioned, a common practice is purging all

All grease is designed to perform to a specific set of parameters and conditions. All greases may overlap in certain areas when it comes to operational temperatures, but it is important to keep within those parameters. So selecting the correct grease to suit a particular application isToessential.thisend all the operating conditions that the bearing or unit is expected to perform in must be known in order to recommend the correct grease. It is not advisable to merely recommend a grease based on what a customer is currently using as they could be using an incorrect product. Greases are a mixture of chemicals that could react very differently to each other if mixed meaning that different greases may be incompatible. It is thus important to know which chemicals can be mixed safely and which cannot. We therefore recommend that customers and end-users consult a SKF expert.

There is an incorrect assumption that a bearing must be filled with grease until clean grease is pushed out the other side of the unit. In other words a bearing must be full of grease to be properly lubricated. Unfortunately this method drives up costs in two ways - unnecessary grease wastage and seal damage.

And there are environmental benefits too.

Another fallacy is that grease is grease. It is commonly believed that EP2 grease is suitable for every application, from door hinges to fan applications. Many operators reason that as long as a bearing or unit has grease in it, it is lubricated and will not fail and that universal grease will do. This is most certainly not the case. It is important to determine how grease actually works and to understand terms such as ‘Thickener’, ‘Base Oil Type’, etc. In a simple test placing grease on paper, a film will start appearing around the grease. This is the base oil ‘leaking’ out of the thickener. If that grease is warmed up, the rate of ‘leaking’ would increase as the thickener loses its retention properties. Thus, as the heat increases, the faster the oil will leak. It is also important to remember that it is the oil and not the thickener that lubricates the bearing. So logic dictates that the oil will ‘leak’ from the thickener at a much higher rate in a bearing designed to run at a high temperature. Eventually the bearing will fail because there will no longer be any oil to lubricate the unit. So SKF has designed a grease that will ‘leak’ at a slower rate under higher temperature, making sure that the oil leaks enough to lubricate but not so much so that it runs out or separates completely from the thickener.

Best lubrication practises will extend bearing life and optimise machine/plant availability

46 Pipes, Pumps and Valves Africa - Jul/Aug 2022 BEARINGS

Bearing in mind that 50% of all bearing failures are due to incorrect lubrication or contamination, SKF highly recommends that best practices, or at the very least, standard practices be followed when it comes to bearing fitment, removal and alignment methods. This will contribute to massive time and cost savings through extended machine life cycle, optimised plant availability, improved uptime and productivity.

the old grease out and ensuring that there is only clean grease in the bearing. Excessive grease can have a massive negative effect on the life span of the bearing.

Once the bearing is in operation the grease will need to be topped up; once again this can be calculated based on the operating specifications. However, if a specific bearing requires 4 grams of grease every second day, for example, how is it possible to know that the correct quantity is being applied? Most lubrication operations are carried out manually using grease guns, bringing in the human Theelement.stroke of the grease pumps’ actuating lever differs from person to person. Moreover, pump parts wear, no longer delivering the same amount of grease. This scenario also applies to pneumatically operated grease guns. Each operation of the air pump should deliver a certain amount of grease and therefore by simply counting the number of pumps of the air gun should determine the exact amount of grease that has been delivered. However, lubrication audits often determine that lubrication points have been under- or over-lubricated using pneumatically-operated units. One solution is the use of grease meters on all the lubrication equipment. Lubrication points should also be clearly marked with the grease type, amount and

By simply looking at how a bearing works makes it is easy to see why purging is wrong. When a bearing rotates, the rolling elements also rotate. If the bearing is filled to capacity with grease the rolling elements lose their rotation ability and they begin to slide, causing friction and subsequent heat. This leads to wear and ultimately failure in a shorter time period. It is possible to do a calculation for every bearing in every operation to ensure the correct amount of grease is applied. This is known as the initial fill and most engineers can calculate this quantity.

frequency of lubrication. Contamination, which is defined as “the action or state of making or being made impure by polluting or poisoning,” will cause a machine to fail if it remains unchecked. There are a number of ways that lubrication can become contaminated including cross-contamination of different types of grease, dust contamination and the ingress of water or other forms of liquid. This is where sealing systems play a critical role. However, even the ‘best’ sealing system will fail if it is being filled with contaminated grease or oil. When a bearing is filled with grease, the actual lubrication is being carried out by the base oil being ‘leaked’ into the space between the surfaces of the bearing. The lubricating film between the contact surfaces being lubricated, when the unit is at full operating temperature, is between 0,1 and 1 micron thick.

A grain of dirt 10 microns in size, which cannot be seen with the naked eye, will push the lubricating film away with Incorrectease. fitment methods, over-or under-lubrication and contamination - these three factors relate to 66% of all bearing failures. Consider two identical bearings manufactured to the exact same specification, in the same factory with one critical difference - one will produce 1,000 hours of service. The other will provide 10,000 hours service owing to best practices in terms of fitment, removal and alignment methods, using the correct lubrication (the 5 R’s) and reducing contamination risk. This can lead to massive savings over the long term and contribute to maximised operations and ultimately business sustainability.

From the Central African Copperbelt to South America, the range has proven its worth in challenging abrasive and scaling applications in mineralsprocessing plants.

“This design feature is due to the unique through-port gate, which makes permanent contact with the polyurethane sleeves, even when fully open,” reveals Labuschagne. Slurry knife-gate valves with fully energised sleeves that need to expand sufficiently to form a seal with the gate retracted are prone to premature wear due to entrapped solids that damage the seat when the gate is next closed. “A through-port gate eliminates the problem, not only extending service life, but increasing plant availability significantly,” adds TheLabuschagne.ARVALV® range has been tried, tested, and proven to deliver superior performance in diverse applications, including dewatering slurries (such as ferrosilicon), cyclone suction/feed applications, dense media separation, concentrate transfer, booster and storage facility tailings, pump isolation applications, wet and dry hopper applications and pulp and paper feedstock. Labuschagne, who has a Bachelor of Engineering degree from North West University, began working at AR Controls directly upon completing his studies. He is the Head of Department for Engineering at AR Controls’ South African head office, where the engineering and draughting departments report into him. His main role is to oversee and manage product and service development and optimisation and to provide engineering support to the sales and production functions within the South African context, while also forming part of the greater engineering team that ensures global alignment of products and services across AR Controls’ multinational platform. These functions fall under the close supervision of AR Controls CEO Julien van Niekerk. Paying regular visits to client sites is what continues to differentiate AR Controls in terms of its customer support and backup, stresses Labuschagne.

Owing to the fact that this contributes so highly to the municipalities’ bill, it also means it has the greatest potential to be the starting point of electricity saving measures. By engaging in energy measures within the water and wastewater infrastructure cycle, municipalities stand not only be fiscally but also energy efficient going “Weforward.have found that the aeration stage is one of the stages which consumes a lot of energy as it requires large pump systems and municipalities may not always pay attention to this aspect and may neglect to overhaul due to the expensive nature of more energy efficient systems. However, what is important to remember is that although the expense may be high at the start, the benefits of cost saving, in the long run, will be worth it,” explains KSB Pumps and Valves’ Hugo du Plessis, senior project engineer. He continues that the most energy consuming aspects within the water services system relate to the stages of water treatment and pumping. He reiterates the importance of how the implementation of energy efficient systems will not only help municipalities obtain, retain and improve their Green Drop and Blue Drop certification but will also eventually allow customers to see the difference in their rates and taxes bill.

Withinfrastructurenoendinsightforloadshedding, it’s important for municipalities to start engaging in energy efficient mechanisms in their water and wastewater infrastructure. This infrastructure is one of the biggest consumers of energy within a municipalities’ operations and it is critical to start looking at ways to implement energy efficient measures within these operations.

According to the guide compiled by Sustainable Energy Africa, Sustainable energy solutions for South African local government: a practical guide, in 2017, “the indications are that on average water and wastewater accounts for some 17% of energy consumption in a South African metro. In terms of electricity consumption alone (i.e. excluding liquid fuel use for vehicles), the proportion is far higher – often representing as much as 25% of the entire municipality’s electricity bill.”

“Inefficient pump systems will not be able to keep up with the ‘backlog’ of water when loadshedding occurs.

In a time when the consistent provision of water, hampered by challenges like aging infrastructure, has become paramount, technology and more specifically telemetry has stepped to the fore to offer workable solutions to utilities and water infrastructure operators.

A complete, integrated sensor-to-enterprise solution that will go beyond addressing the most challenging remote monitoring and control applications and help utilities and operations manage and run secure and reliable water infrastructure.

3. Data Safety - If communication at a remote site fails, operators can rest assured their data is safe, time-stamped and stored locally in the RTU. Once the communication link is restored, the cloud-based SCADA software will automatically load all the data generated during the outage into the historian using data backfilling.

4. Reduce the number of site visits – changes to programs and configuration can be made from the cloud-based SCADA system. The logic file can simply be loaded to the remote SCADA software and sent to the smart RTU using the DNP3 network.

• Optimised maintenance efforts with integrated features to support operators and maintenance staff.

2. Optimised Telemetry Management - A telemetry system will allow organisations to customise their equipment according to specific requirements. By using a SCADA smart RTUs solution and cloud-based SCADA software, Utilities for example, can manage their field assets, including configurations, applications and firmware, from one interface.

• Complete historical record with industry standard and open protocols to support data analytics.

The bottom line

5. Increase the lifespan of the telemetry system – utilise standards that are widely used and accepted such as DNP3 (level 4), WITS1 (worldwide industrial telemetry standard) and IEC60870- 5-101/-104.

“After the cancellation of Electra Mining in 2020 due to COVID, we see this year’s event as an excellent opportunity to see our customers and to display some of our latest products and technology-driven solutions,” says Rajen Govender, Regional Managing Director of Weir Minerals Africa, which forms part of the global, LSE-listed Weir “We’reGroup.

While the African reach of Weir Minerals Africa will be highlighted at Electra Mining Africa, the company will also be emphasising its significant manufacturing capability.

“We’re making a special effort to send out invitations in advance to ensure maximum face-to-face interaction with our Weircustomers.”MineralsAfrica is busy extending its sales and service network across the African continent and the Middle East, with a particular focus on West Africa, which has emerged over the past two decades as one of the world’s growing mining regions.

Weir Minerals Africa, which enjoyed excellent attendance at its stand at the last Electra Mining Africa in 2018, will once again be exhibiting its extensive range of minerals processing equipment at this year’s show where it will have a capacious 300 m2 outdoor exhibit.

The company already has branches in Ghana and Senegal and, in a recent breakthrough, secured its first major order for “OurNigeria.strategic intent has always been to be where our customers need us to be,” remarks Govender. “While we are well represented throughout Africa and the Middle East, we believe there are still opportunities to extend our footprint – and the technologies we offer – to countries where we currently have little or no permanent presence.”

All Weir Minerals Africa’s world-class brands, including Warman®, GEHO®, Cavex®, Enduron®, Trio®, Delta Industrial™, Linatex® and Isodry™, will be featured on the stand, although the sheer size of some of the equipment will limit the ability to have entire units on display.

Weir Minerals Africa will make a particular point of showcasing its digital capabilities, notably its Synertrex® digital ecosystem that is easily integrated into customers’ existing systems. Synertrex® technology enables customers to access all recorded data of their Weir Minerals equipment, as and when required. This information can be integrated into existing control room systems in real time or accessed remotely, around the clock, on any device.

Another high-tech product on the stand will be the Synertrex® InteliWear condition monitoring system for hoses and spools, which can be accessed remotely through a dedicated online dashboard. This provides a complete solution to many of the problems that are faced in maintaining hoses handling highly abrasive materials. It eliminates the need for physical inspections and averts costly downtime.

“We will probably have a larger jaw crusher on show,” says Govender. “Visitors can also expect to see some of our Warman pumps, our rubber products and hoses, the Enduron range of screens and HPGRs, as well as our latest Cavex 2 hydrocyclone, which marks a major leap forward in hydrocyclone technology.”

“Equipment that cannot physically be accommodated on the stand will be represented by 3D models and illustrated via audio-visual displays.”

The Weir Minerals Africa exhibit will also highlight the ability of the company’s products to reduce consumption of resources such as energy and water, thereby allowing customers to achieve their sustainability goals.

“Electra Mining Africa is a big commitment for us and we are pulling out all the stops to ensure that visitors to our stand will have a rewarding experience.”

“Our products and solutions address virtually every aspect of comminution and minerals processing and we will have many of our technical experts on the stand to engage with visitors and explain how Weir Minerals Africa’s equipment can lower costs and enhance productivity,” says Govender.

Clayton Ellary, from Aon South Africa’s Commercial Risk Solutions, explains that as pressures mount, more and more cases of underinsurance are being recorded. “Underinsurance is when insurance cover in terms of sum insured is not sufficient to cover the full cost of a potential claim. It can apply to a property, plant and machinery, business interruption and even exposures like cyber liability and Directors and Officers cover. In fact, any area of insurance can be impacted by underinsurance with potentially severe consequences for the balance sheet and the ability of the business to recover from an uninsured or underinsured loss,” explains Clayton.

• If an insured selects an indemnity period of less than 12 months, the Gross Profit sum insured should reflect 12 months – this is in accordance with standard policy terms and conditions.

5 Trends driving business underinsurance

Example: Claim: R200 000 Sum Insured: R1 000 000 Replacement value: R2 000 000

Avoiding the financial ramifications of not having sufficient cover for a claim. Many businesses are faced with an increasingly volatile political and socio-economic climate. Not only are businesses having to manage a whirlwind of change and disruption in their business models, such as technology, changing consumer behaviour, socio-demographic shifts, climate change and the pandemic, but they’re also being confronted by a heavily constrained economy and rising inflation.

The underinsurance calculation is calculated as follows: Sum Insured / Correct Replacement Value X Value of Claim R1 000 000 / R2 000 000 X R 200 000 Claim settlement = R100 000 “As illustrated, the implications of under-insuring your assets can be severe as you run the risk of being inadequately indemnified in the event of a loss due to the application of what is termed the ‘Average formula’,” Clayton warns.

• The steep rise in costs of labour and materials, exacerbated by exchange rate and commodity volatility is making repairs and replacement of machinery, equipment and property far more expensive. Property values are also on the rise, adding extra pressure in this space.

• If an insured elects an indemnity period of longer than 12 months, then the Gross Profit sum insured should reflect that period. In addition, if the indemnity period is 24 months, the trended Gross Profit should reflect that period.

• Increased insurance pricing, reduced reinsurance capacity and restrictions in the scope of cover have created significant challenges. It’s one reason why we have seen a hike in insurance pricing – by as much as 50% or more in some instances and lines – as well as restrictions in cover and even markets withdrawing from certain industry sectors as

Using a property claim as an example, Clayton explains how underinsurance occurs: Following a loss, your insurer will calculate the replacement value for which you should have insured your buildings or contents. If your sum insured is less than the actual replacement value, your insurer will pay a proportion of your claim.

54 Pipes, Pumps and Valves Africa - Jul/Aug 2022 NEWSINDUSTRY

• Business interruption indemnity periods are often not sufficient for the true scale of an insured event. Claims costs are also on the rise, notably in areas such as Directors & Officers Insurance (D&O) and cyber liability - all leading to insurance limits that need to be increased.

Aon highlights 5 factors driving the business underinsurance trend, including:

Aon South Africa Pty Ltd, +27 (0) 86 010 www.aon.co.zainfo@aon.co.za,0404, than the actual period of disruption caused by accidental property damage. It is worth considering an increase in your maximum indemnity period to reflect the true extent of disruption, including allowing for an increased time for reinstatement,” says Clayton.

“It is also becoming more relevant but more challenging to insure loss of profit or revenue during an interruption that results from a customer or supplier incident, as supply chains become more fragile.

It is well worth the effort to engage with a risk advisor who specialises in the field to understand and map out the true extent of supply chain risks your business could potentially face to mitigate and transfer the risks,” he Don’tadds. let underinsurance scupper your business’ ability to recover from a major event. The interconnectivity of traditional and emerging risks demands a more holistic approach.

reinsurer appetites wane. • Often, insureds don’t keep pace with the impact of volatility and changes in their operating environment which means that their valuations are inaccurate and out of date. Some businesses will erroneously insure for the market value of their premises rather than considering what it will cost to rebuild at today’s prices. It may also be that a business has changed its operating model and as such its exposures have changed, but it is still using previous, outdated valuations that are irrelevant to the changed business circumstances – for example holding more stock on premises to counter supply chain vulnerabilities, or the very nature of the business has changed, as we saw happen during the pandemic. Consider for example office premises that now have retail or manufacturing tenants and what this means for the declared risks on site.

Preventing underinsurance Underinsurance is a potential financial pitfall that can be avoided by setting the correct sum insured on all policy sections of your cover, conducting proper valuations and engaging with a professional risk advisor or broker to get the balance “Forright.your Buildings, Machinery, and Plant we recommend that you undertake regular replacement valuations, considering the impact of new replacement cost, VAT, inflation and exchange rate fluctuations. These valuations should include the actual cost of rebuilding or replacing any of these items at today’s costs including demolition, clearing costs, professional fees and any other improvements to the property insured. An expert broker in the field would be able to arrange a professional reinstatement valuation that will allow you to be better informed of the true replacement value of these items,” Clayton explains. On average, 43% of business interruption insurance is underinsured by 53%, according to the Chartered Institute of Loss Adjusters (CILA).

“One of the reasons for this is that the selected maximum indemnity period turns out to be far shorter

“Fact-based will be well worth the effort to engage with an expert broker to comprehensively identify, evaluate, quantify and mitigate risk with a solutions-based management approach that takes a long-term view and collaborates with all roleplayers throughout your business value chain.” Better decisions start when you are better informed of the risks you are faced with, and their interconnectivity with other factors,” Clayton concludes.
