COVER STORY

In a rapidly changing and increasingly competitive landscape One pump company is taking the initiative to grow its footprint and its market size. Pipes, Pumps and Valves Africa met up with the new management of Pumps For Africa to find out more. End users are increasingly demanding integrated solutions across a broad range of engineered products while minimising supply-chain complexity. Pumps For Africa, South Africa’s first and longest operating online pump store, have a solid history of supplying a range of solutions to businesses all over Sub-Saharan Africa. Director Nic Winslow says the company has a long-standing reputation for its

excellent products and services. “Growing the business from this base has been our priority,” he says indicating that the company is the first choice in pump suppliers to a majority of industrial, mining, and process companies. “We also supply the public with pumps needed for domestic purposes like boreholes, fish tanks, water features and the like. No pump is too big or small.” It is in this diverse offering that Pumps For Africa’s strength lies, explains Winslow. In recent months the company has become a Grundfos authorised distributor, a Southern hemisphere distributor for Ebara, a KSB agent as well as RNE Pumps. “In the current economic climate, the business case for diversity is stronger than ever. We believe it is an important asset for the company’s growth,” says Winslow. “ Diverse offering The benefits of a diverse and wide range of products hold many benefits for their customers, according to Winslow. “It is about creating an environment where our customers can have all their pump needs effectively met. The quick delivery of ordered pumps is one of our biggest goals. It is not just about having a diverse product range, but also being able to deliver the products efficiently and as quickly as possible.” Winslow says by being more diverse the company finds itself in a position to constantly improve keeping turnover at high levels. “It also ensures we remain competitive and ahead of the pack. It is an increasingly competitive market out there. Agility, flexibility, diversity are what makes a company stand out.” As part of its work towards delivering an improved and more diverse service, the company has teamed up with First Seal, one of the leading mechanical seal manufacturers in the country. This allows Pumps For Africa now to not only supply mechanical seals and gland packing but also repair and refurbish mechanical seals. “We have increased our overall after-sales services and we guarantee post-sales technical assistance with pump repair and sparepart supply even after the standard warranty period,” says Winslow. “We also offer maintenance and repairs on pumps. We have in house facilities

and friendly staff to strip pumps and quote on repairs, rewinding, mechanical seal and bearing replacements, motor rewinds, even new paint, leaving your pump looking brand new.” Winslow says with some 44 brands on their books the company has been able to extend its client range as they can meet a wide variety of needs. Lead times to deliver are also much faster reducing downtime at plants significantly. “One of the bigger benefits is that a client needs a variety of pumps for several operations can make one call and have all their needs met. It is far more efficient a process also from a cost perspective.” Standing out through innovation Another important development at Pumps For Africa has been its move to invest in research and development. “Innovation is an important part of our strategy,” says Winslow. “It is not just about being able to service the full market by delivering quality products, good aftersales service and maintenance, but about improving their operations and minimizing cost as much as we can.” Cost remains a driving force in the pump industry. ”Reducing overheads and containing cost is at the forefront of all operations no matter the sector. Finding innovative and cost-effective solutions makes sense and will bring huge benefit to our customers.” Director Dennis Winslow adds that with topics such as resource efficiency and sustainability gaining hugely in importance, it has made sense to invest time and effort into innovation at Pumps

New solutions on the table The mining industry is one of the sectors that have been under tremendous pressure to streamline operations, minimizing cost and reducing the amount of electricity used. With this in mind, the Pumps For Africa team have worked hard to deliver a new impeller for slurry applications that decreases electricity usage ultimately reducing cost by as much as 40%. “The impeller is designed as a total replacement and nothing on the pump has to be modified to accept it,” explains Winslow. “Essentially the product draws far fewer amps than a normal impeller.” The product has been the outcome of much work on the mechanical seal side at First Seal. “Our work on mechanical seals onto slurry pumps led to the development of the impeller,” explains Winslow. “We believe this product can make a world of difference to the cost of operations especially in the mining sector where energy usage is high.” A second innovation has been the development of XPEL-IT, a new generation labyrinth seal, that ensures no water or any other product enters the bearing housing.

COVER STORY

For Africa in recent months. The company are proud to deliver two brand-new products to the market that they say will make a difference to operators wanting to contain cost and introduce more efficiency.

“We can virtually guarantee this as there are four areas where we seal ingress,” says Winslow. “This is a miniature pumping system that pumps the product out before reaching the bearings. It can be fitted to any make of pump and uses a propeller system. Pumps require no modification to have this product fitted.” A main benefit is the durability of the components used for the product making replacement unnecessary unlike the case with traditional rubber components used to keep liquid out of bearing houses. “The life expectancy on this product is massive. The only thing that could make it fail really is if the whole pump fails or if it is inadvertently damaged with a tool of some sort.” Pumps For Africa, +27 (0) 10 594 0335, info@pumpsforafrica.co.za, www.pumpsforafrica.co.za

Correct pump selection essential for effective dewatering Dewatering is one of the most commonplace activities on mining and construction sites across the world. However, it is also one in which the incorrect selection of pumping equipment could have a major negative impact. Lee Vine, managing director of Integrated Pump Rental, cautions that different dewatering applications calls for different solutions, and that it is not always a case of one pump fits all. As an example, he explains that dewatering on a mine or quarry site requires robust equipment capable of withstanding the harsh operating environment, and more often than not pumps engineered to remove sludge and liquid containing solid particles. Commenting on incorrect pumping equipment being selected for a given dewatering job, Vine says that this happens primarily because of a lack of understanding of dewatering applications, as well as a lack of knowledge when it comes to pumps and pump design. “Most customers need a trouble-free pumping solution, and this means that the pump must be configured for the specific dewatering application,” Vine says. It is imperative that the pumping solutions supplier is able to accurately assess the site dewatering needs, and only then can an optimum dewatering plan be proposed. Factors such as the required capacity, suction lift and discharge head are important as are the basics such as access to power and logistics in reaching the actual site. Integrated Pump Rental has built its success on providing fit-for-purpose dewatering solutions to its customer base, and the company operates an extensive fleet of pumps that caters for all type of application requirements. As part of its total round-the-clock pumping solution, Integrated Pump Rental takes complete responsibility for all maintenance of pumps on site. This includes the keeping of a complete maintenance record which facilitates proactive, scheduled maintenance and optimum uptime for the pump installation. Included in the rental fleet are the well-known Grindex submersible drainage and dewatering pumps, the locally engineered

and manufactured SlurrySucker dredge units, the SlurryBlaster hydro mining equipment solution and Sykes dewatering pumps. Significantly, popularity of the Sykes dewatering pumps has gained rapid traction since introduced into the Integrated Pump Rental fleet just over a year ago. Vine says that it is the ease with which these pumps operate that has driven the market acceptance. “Sykes pumps are simple to use and can handle high volumes of water with ease, but more importantly the pumps are available mounted on skids, site trolleys and road trailers. This makes the deployment of this pumping equipment an easy and rapid task,” Vine says. There are four different ranges available locally. Pumps in the Sykes Contractors Range are fully automatic priming and can run dry for extended periods of time without damage. The pumps which have a suction lift up to 9 metres can handle solids up to 90 mm. The Medium Head Range is engineered to perform reliably in both high water flow and long pipe run applications. These pumps have an efficiency rate of 77% and can handle solids. The Sykes Himax Range offer what is claimed to be one of the best shaft stiffness ratios on an automatic priming pumps, these pumps handle solids up to 75 mm with ease. Capable of handling particularly high pressures and loads without compromising its operation, the Sykes Extra Range is designed for efficient and effective dewatering in harsh operating conditions, such as those found in open pits and quarries. Vine says that although possibly best known in the South African rental market for its diesel driven units, it is important to emphasise that Sykes do not only supply driven diesel dewatering pumps. “The Sykes range can be coupled to electric motors with VFDs so a complete curve or pumping range is available to the customer in a permanent application,” he says. “What Integrated Pump Rental has proven to date is that coupling our team’s expertise in dewatering with quality pumping solutions we have been able to assist customer with round-the-clock pumping support,” Vine concludes.

Full-service capability vital for reliable pump supply Even the best quality pumps need to be supported with a full range of aftermarket services, according to Jordan Marsh, sales manager at Integrated Pump Technology. “Reliable pumping is the life-blood of many sectors in our economy, making the choice of pump supplier a strategically important one,” says Marsh. “This applies even when customers have specified the best pumps available.” He highlights, for instance, that Integrated Pump Technology is so confident of its Grindex range that it offers a 36-month warranty on all new pump units purchased. The expected lifespan is, of course, much longer than this, he says, and the company is well equipped to ensure customers long and reliable performance. “Our fullservice offering includes a comprehensive stock of all critical spares across the range, with a service centre and experienced staff to maintain units to OEM standards,” he says. The necessary equipment and expertise are on hand to look after the complete range of pumps, from the 0,4 kW units right up to the large 90 kW Grindex Bravo Mega pumps. Integrated Pump Technology also supplies and 10 10

supports Faggiolati slurry pumps and Leybold vacuum pumps, and can even service and test other brands of submersible pumps. Among the technical services in the company’s quality-accredited workshop is its test tank, which allows comprehensive testing of pumps with motors up to 150 kW. According to workshop manager Fred Slabbert, the continual investment in workshop capability means that customers can benefit from a six-month warranty on refurbishments and repairs. The workshop can even conduct full refurbishments. “Pump users can bring us their equipment for a professional assessment by our skilled technicians,” Slabbert says. “After careful examination, we generate a condition report which gives all the details necessary for an informed decision, and customers are assured of aftermarket services to OEM standards.” Underpinning the company’s high service levels is a dedicated workshop sales administrator, providing a strong link between customers and the workshop and spares store. “We prioritise quick and efficient turnaround times on all spares sales, repairs and quotes, keeping customers informed at each step in our relationship,” he says. In the unlikely event of a customer needing assistance on-site, the workshop is also equipped to provide trouble-shooting assistance on most mechanical or electrical issues.

Atlas Copco partners with the distributor, BMG Mozambique, to support customers in the region

PUMPS

In keeping with their customer-centric mindset, Atlas Copco business areas, Power Technique and Compressor Technique, ensure seamless product and service delivery to their customers in Mozambique through their distributor, Bearing Man Group (BMG) Mozambique. Established in 1974, BMG has an aggressive global and African growth strategy and is always on the lookout for opportunities that make sound commercial sense. In 2004, the organisation opened BMG Mozambique which, with a network of nine branches, serves a wide range of sectors across the region including mining, construction, food and beverage, sugar, cement, oil and gas. BMG Mozambique was appointed as an official distributor for Power Technique in October 2017 and less than two years later as a distributor for Compressor Technique. “Getting closer to customers, especially those in more remote areas, is an integral part of our business strategy and our distributors, as our route to market, are helping us to achieve this goal,” states David Stanford, Business Line Manager for Power Technique’s Portable Products. “Other motivating factors for partnering with distributors are their in-depth knowledge of customers and local industry and their strong presence in their markets.

Pipes, Pumps and Valves Africa - Sep/Oct 2021

Mozambique’s vast business potential convinced us that we needed a solid foothold in the region via a distributor to ensure that customers have access not only to Power Technique’s product offering but also to all our service and after-sales solutions. As our working relationship with BMG Mozambique dates way back to around 2014, we knew they would be a good fit, sharing the same synergies with Atlas Copco’s culture of openness, diversity and inclusiveness, and having the necessary skills levels and capabilities to support sales.” BMG Mozambique supplies Power Technique’s complete range of portable generators, pumps, light towers, compressors and pneumatic tools as well as accessories, service kits, spares, lubricants and related services. As BMG Mozambique had also been supplying a few products from the Compressor Technique stable on a caseby-case basis, they were familiar with the business area and had gained experience and knowledge of the product

“We are extremely proud to be a distributor for Atlas Copco’s two business areas, particularly as the good work we performed on the Power Technique side played a role in Compressor Technique also appointing us as their distributor,” comments Antonio Clemente, Product Manager of Tools & Equipment Division at BMG Mozambique. “As a globally renowned and respected brand, Atlas Copco is a perfect fit to the rest of our product offerings and we are seeing tremendous added value through our association with the company. Having access to their top of the range equipment and services has uncovered new markets and opportunities for us. This leading brand in both compressed air and power/ construction equipment has opened doors to our existing and new customers to whom we supply top-notch products with all the associated benefits of high performance, efficiencies, reliability, long service life and low total cost of ownership.” Antonio considers it their responsibility to promote, sustain and safeguard the Atlas Copco brand in Mozambique in an ethical manner. “I would like to reiterate our firm intent of promoting and expanding Atlas Copco’s presence in our territory both through the sale of new units as well as the servicing of existing units. We must ensure that customer service is always performed at high levels and that we service all equipment, both existing and supplied by us, either with our own teams or with support from Atlas Copco South Africa, so much so that our customers see us as an extension of Atlas Copco.” David and Daryn stress that they too have a responsibility towards their distributors in providing all necessary support and training to help further develop and grow their businesses. “Our product managers and technical specialists offer expansive support to BMG Mozambique, sharing product and technical information and knowledge, assisting with trouble-shooting, and providing training and advice via online platforms, direct calls and regular site visits.” As their dedicated Business Development Manager, Daryn is the direct liaison between the distributors and Compressor Technique. “Over and above paying regular regional visits to their premises, I join them in customer meetings to show customers that our distributors have the full support from Atlas Copco.”

Power Technique and Compressor Technique also support their distributors through several smart online processes including shop online, parts online, warranty online and Toolbox which David points out are extremely popular with the distributors. “These online platforms keep us interdependent and connected to our distributors. We also encourage them to draw their information from our current and up-to-date webpage and they can use our convenient technical training question system, My Quest, if they have any questions.”

offering. “We had heard some great things about BMG’s progress in Mozambique as a Power Technique distributor and we decided that we want that kind of professionalism in our business area too,” says Compressor Technique’s Business Development Manager - Indirect Sales, Daryn Jack. “As BMG Mozambique is ultimately an extension of our business in the region, it was important that they share our core values, they provide a service that is of sound technical expertise and that their management and sales team conduct business in the same professional and ethical manner as Atlas Copco.” As an authorised Compressor Technique distributor, BMG Mozambique is responsible for supplying products, spares, service kits and lubricants from Compressor Technique’s two marketing divisions, Industrial Air and Oil-Free Air, as well as its service division, CTS (Compressor Technique Service). “In line with our agreement, BMG Mozambique may sell any and all of our product ranges, including newly launched products and their ancillaries,” affirms Daryn.

Antonio considers training as an extremely important support pillar from Atlas Copco, benefitting BMG by empowering employees through improved skill sets and creating awareness of sales and servicing opportunities. Compressor Technique offers several forms of distributor training that includes regular online/virtual product and technical training sessions hosted by its three divisions, as well as onsite training for both distributor and customer technical teams. “We also offer advanced technical training at our training academy based in Egypt,” adds Daryn. David points out that the training provided by Power Technique to the BMG team through Learning Link, e-learning and Microsoft Teams has helped to keep everyone focused and up to speed during the Coronavirus pandemic. “We have been very astute in the way we have been doing business over the last eighteen months to address the challenges centred on COVID 19 coupled with the remoteness of some of our distributors. I am proud of my team for successfully bridging the gaps and seamlessly adjusting to the changed landscape of doing things.” The success of the Atlas Copco partnership with BMG Mozambique is evidenced by the fact that for the last few years they have regularly been one of Power Technique’s top three distributors. “Last year, we finished top between the South African and African distributors!” states a proud Antonio. “Our two-year partnership with Compressor Technique is still relatively new and there have been a few challenges, but we aim to take their top distributor honours in the not-too-distant future.” Atlas Copco Group, +27 (0) 11 821 9800, air.compressors@atlascopco.com, www.atlascopcogroup.com Pipes, Pumps and Valves Africa - Sep/Oct 2021

New high-temperature bearing material

Many pump manufacturers are pleased that Vesconite Bearings has developed Hitemp 160, a nogrease-needed bearing material able to operate up to 160°C (320ºF), and even up to 220ºC (430ºF) depending on the application. This is because they are eager to have one bearing material that can cope with multiple applications and wide temperature ranges. “Companies do not want to continuously adapt their pumps to the wide range of chemicals and temperatures that they might encounter,” says Vesconite Bearings CEO Dr Jean-Patrick Leger. “Even if 90% of the pumps they sell are for cold-water applications, they don’t want to change bearing materials and wear rings for the 10% of cases where they will be exposed to high temperatures, solvents, or acids and alkalis,” he states. With the introduction of Hitemp 160, pump companies can be assured that their bearings and wear rings will cope with temperatures up to 160°C; will not swell; are low-friction; have excellent chemical resistance; and are suited to contact with cold water, hot water and steam.

Decades of innovation elevate Warman® mill circuit pumps

PUMPS

Doing duty as an integral part of a mine’s minerals extraction circuit, Weir Minerals’ Warman® mill circuit (MC) slurry pumps withstand the harshest conditions while delivering their mission-critical function. Marnus Koorts, Weir Minerals Africa’s product manager for pumps, emphasises that a mill circuit pump must deal with relatively large rock fragments from the primary mill, which can rapidly wear the pump’s throat bush, impeller and volute liner. “If this installation is not optimised, the abrasion could reduce the pump’s wear life to a matter of weeks,” says Koorts. “The significance of wear life is high, as the whole mill circuit comes to a halt when the primary mill’s circuit pump stops – potentially affecting minerals extraction for the whole mine.” He highlights that the company’s Warman® MC pump range is regarded as a global flagship for the mining sector, evolving over more than eight decades of continual development and innovation. A considerable portion of Weir Minerals’ total R&D investment – which sees 1,3% of its total global sales being ploughed back into product improvement – is directed toward these pumps. “Over the years, we have developed many unique and ground-breaking innovations,” he says. “For instance, we developed the adjustable throatbush, a technology that we have advanced ahead of our competitors.”

This innovation optimises the efficiency of the pump, ensuring that the gap between the rotating impeller and the casing is kept at the minimum specified. This, in turn, reduces recirculation and ensures that the pump’s operating efficiency is routinely restored. The addition of deep expelling vanes on the high-pressure side of the throatbush diminishes the formation of eddies, which means less turbulence and better hydraulic efficiency. Minimising recirculation also cuts the pump motor’s energy consumption, generating savings on electricity costs that quickly justify the investment in a Warman® pump with this capability. “Ease of maintenance is another priority with the Warman MC pumps, allowing for quick and safe repair procedures,” he says. “The quick changeout system of the pump’s wet end is a key innovation, as the entire wet end can be unbolted and removed from the bearing and drive assembly shaft – taking hours off the time required to replace wear parts.” Concerning the materials used, Weir Minerals has developed a wide selection of materials for its throatbushes and lining impellers and pump volutes. While most slurry pumps on the market use high chrome metal in these applications, the company also offers various rubber compounds and a hybrid Warman® MCR-M option – a metal-lined volute that is interchangeable with a rubber lined volute. An in-house optimisation team – using 3D scans of the mine environment and computational fluid dynamic (CFD) analysis of the slurry flow – helps customers achieve the full benefits of Warman® MC pump innovations. In this way, performance improvements can be modelled even before installation takes place, says Koorts. Weir Minerals, +27 (0) 11 617 0700, sales-za@weirminerals.com, www.minerals.weir

Understanding torque in pump system installation & maintenance

PUMPS

The accurate measurement of torque is a game-changer for pump reliability and efficiency. Understanding Torque & Its Importance One example of torque is to think of pushing or pulling a wrench to loosen or tighten a bolt. That turning force is torque, as Viking Pump explained in a Pye Barker Engineered Solutions guest blog. Torque can be calculated by using horsepower (hp), a constant and speed (rpm, or rotations per minute). Horsepower is the combination of torque and speed. If 1 hp is equal to 550 foot-pounds per second, that is 33,000 foot-pounds per minute. And when using horsepower for the calculation, the constant is 5252. Therefore: T = (HP x 5252)/speed. Torque comes into play in pumping systems because for a pump to start, a motor must create the power needed to produce enough torque to start the pump and bring it up to the best operating speed. If the motor doesn’t produce enough torque, the pump will not start or it may operate at a speed that’s too low, as explained in an article by PumpWorks. When starting a pump, the motor has to be able to overcome the pump inertia and static friction (aka, stiction). With static friction, the frictional force resists force that is applied to an object. This object will remain stationary until the force of static friction is overcome, according to Britannica. This means that, even when the pump is at rest, or 0% full load speed, the full load torque

must be at 20% to overcome pump inertia and static friction. Then, as the speed of the pump increases, the torque needed declines. What Are the Advantages of Torque Sensors? Torque sensors can turn mechanical torque—the force used to turn the pump—into an electrical signal. With these torque meters, users can determine the rotating device’s torque, speed, power and efficiency. Because determining torque is such an integral part of operating a pump and doing so efficiently, a torque sensor device can lower costs associated with testing pumps and produce highly accurate data, which is necessary when selecting the right pump and motor combination for a particular application and facility. One type of torque sensor is the Bearingless Digital Torquemeter offered by S. Himmelstein and Company. This sensor is highly accurate, and its repeatability makes it a preferred sensor for power and efficiency testing. The Bearingless Digital Torquemeter does a few things differently than some other sensors: The Bearingless Digital Torquemeter allows mechanical mounting advantages thanks to not using any bearings. The sensor has a flanged end configuration and is connected to the shaft between

PUMPS the pump and the motor using flexible couplings. These couplings compensate for the misalignment resulting from connecting two shaft ends and the inability to get them lined up perfectly. Bearingless sensors have reduced maintenance as opposed to a transducer with bearings since it is not necessary to be concerned with bearing wear and re-lubrication. In many pump testing areas—known as test cells—space is at a premium. This flange-style and coupling arrangement requires less installed space. In addition, in the case where pumps and motors might be close-coupled, it may not be possible to accommodate the space required for a shaft-style unit. The Bearingless Digital Torquemeter ensures accuracy. Users can expect the best possible measurement is being produced, with low combined error. Consequently, they can rely on one sensor, rather than needing several sensors, to maintain accuracy over a broader range of horsepower’s and still be within the recommended Hydraulic Institute uncertainty guidelines. Requiring fewer sensors results in costs savings. A single 0.01% Code J Bearingless Torquemeter, with more than 10 times the useful range of a 0.1% sensor, will still provide more accurate results than multiple 0.1% sensors handling the same torque/hp range. Again, this results in more accurate data, lower sensor capital cost, lower test bench cost and operational savings by eliminating sensor changeovers. The Bearingless Digital Torquemeter can feed data directly into a facility’s existing data acquisition system. Data is digitized on the rotor making it more immune to noise and signal coupling variations. The data is sent to the stator without physical contact where it is manipulated by multiple microprocessors. This digital output from the sensors are connected to software provided by S. Himmelstein and installed on existing hardware or the output can be imported directly into a user’s own data acquisition system. The Bearingless Digital Torquemeter can work in a vertical arrangement. In a vertical pump test setup, sensors must support significant hanging weight and potential extraneous thrust loading. With a bearingless design, the sensor is capable of handling the increased thrust loading evident in a vertical application with little 22

to no impact on durability and performance. “Hydro Performance Test Lab, Inc. is an independent/aftermarket pump testing facility. We test pumps of all different types and sizes. Given our scope of work, we see many different vertical pumps with different design speeds. Using our test motor to operate these pumps has allowed us to use a known motor efficiency when calculated the pump input power. This “known” motor efficiency is nothing more than a nominal value that can be found on our motor nameplate. Since the motor efficiency is nothing more than a nominal value, we know that the pump input power calculation is only so accurate up to a certain degree. If we test a pump with a design speed significantly less than the rated speed of the motor, that motor efficiency value is now useless. After some research and redesign work on our side, we were able to incorporate the Bearingless Digital Torque Transducer into our dedicated machine train arrangement. Making the proper modifications to our machine train arrangement was fairly simple and allows for a very easy installation. Since this has been added to our setup, we have found that our test results have been more accurate and repeatable. We can now present our customers with more accurate and repeatable pump input power data, which also provides them with a more accurate efficiency c urve and performance report.” Thomas Papadakos, Test Lab Manager at Hydro Performance Test Lab. Additional Features Two challenges that all users face with pumping systems are natural frequency and vibration during operation. With the latest S. Himmelstein Bearingless Digital Torquemeter, a short driveline—or a reduced axial installed length—offers significant advantages. The shorter driveline and high sensor stiffness result in higher natural frequency and reduced vibration. Higher natural frequencies give a more dynamic response and better accuracy. These sensors are also designed to handle both overload and over range. These two specification parameters are characteristic of all S. Himmelstein sensors. Overload represents a mechanical safety factor for the sensor

element. It refers to the maximum load limit of the sensor before yield or physical deformation. In the case where the torque exceeds the sensor full-scale rating, it will not have a mechanical failure. Overrange relates to the sensor’s electrical output signal. It represents how far the output voltage will extend beyond the sensor full scale before it clips. In the case where users operate beyond full scale, the sensor will still provide valid data. The advantage to a sensor being able to handle overload and over the range is the data collected is free of errors from clipped torque peaks. Pump test data is not particularly stable, shows a lot of variabilities. Consequently, it is necessary to average the data over longer periods, and users will want to capture all of that data so they can analyze the best representation of

Understanding the criticality of measurements such as torque, speed and more, S. Himmelstein designed the Bearingless Digital Torquemeter to produce precise data and ensures that precision with accredited calibration documentation. The accredited, bi-directional ISO/IEC 17025/2017 calibration and true, bi-directional rotor shunt calibration check is standard. The user’s confidence and comfort with these measurements are imperative, hence obtaining a fully accredited calibration certificate for a unit is imperative. The user can be assured that the sensor was calibrated using primary standards traceable to national standards and performed in an accredited laboratory. Each sensor comes with a certificate of that calibration.

PUMPS

performance. If the peaks are clipped off, the averaged data will be less accurate. Finally, two additional features that provide peace of mind for users are the ability of the sensor to handle significant extraneous loads and a fully accredited calibration certification. Protection from influencing the torque signal is important, so high immunity to extraneous loads is essential. For example, with vertical applications, users would not want the hanging weight or thrust loading to create “cross talk” and influence the torque measurement. Therefore, the sensor must be able to withstand these loads without affecting the torque readings. The Bearingless Digital Torquemeter uses multiple strain gage bridges to cancel extraneous loads and also reduce the adverse effects of the temperature gradient.

How to avoid bearing failures with proper lubrication

ADVERTORIAL

Bearings are a fundamental component of mechanical equipment and centre on the idea of reducing rolling friction to allow parts to move without being destroyed. Reducing friction can contribute to higher performance, better energy consumption and less wear and tear, meaning that proper maintenance and care of bearings is essential to get the best out of machinery and prevent extensive and critical equipment failure. There are numerous reasons bearings can fail, including rust, overheating, wear and fracturing. Many of these issues can be resolved through the correct use of lubrication.

Contamination If lubricants get contaminated by water, chemicals or residue from cleaning solvents, they perform less effectively in a bearing component. To avoid contamination, it’s important to ensure regular maintenance of equipment and to

To avoid both types of failures, goodquality multi-viscosity engine oils have been developed to include “flowability” for low temperatures. LE's oil consumption reducers and drain extending additives improve fuel efficiency, reduce wear and provide allseason, all-weather performance.

Lubrication Engineers (LE) South Africa estimates that improper lubrication causes 20% to 30% of bearing failures. Here are some of the best ways to avoid common causes of bearing failure. Incorrect lubrication If the wrong lubricant is used for a particular application, including not being sufficiently durable for the operating conditions, it can contribute to bearing failure. A good lubricant can help prevent rust, reduce friction and support optimal performance. A good lubricant supplier will be able to advise the correct lubricant to use for any application, and will often provide after-sales support for any troubleshooting at a later stage.

also caused by using an oil that is too heavy in viscosity. When it is cold, a heavy-weight oil will not flow or pump readily. When pumped from the crankcase, it may stay in the upper end of the engine and not return quickly to the pan. If this happens, engine bearings become starved for lubrication and wear prematurely or fail. Premature turbocharger bearing failure is directly related to this oil starvation problem.

avoid contaminating lubricants. One of the best ways to do this is to opt for automated application of the lubricant, which removes human error. Accessories like oil sight glasses and desiccant breathers can also ensure you have an understanding of your lubricant condition at all times and that any moisture contaminating your lubricant is removed. Heavy viscosity Many engine bearing failures are

In general, early or premature bearing failure can be detected during scheduled inspections through an established maintenance programme. These inspections will help reduce dirt and debris contamination, assess lubricant performance, and catch early wear patterns before total failure, which will save money in the long term through reduced maintenance and downtime costs.

Vacuum lifting 7200kg of boxes every day, effortlessly This is the story of how Rockwool created a healthier workplace for their employees by reducing the strain of manual handling. systems from TAWI to minimize the risks associated with manual handling. Now, vacuum lifters and lifting trolleys are used daily to lift and transport various goods and they have become a natural part of the production flow.

The result: healthy and happy employees Since the investment in TAWI equipment was made, the lifters have been used on every shift, every day. Production workers report positive time saving effects since they can now maintain the same work speed all day, without getting tired.

The challenge of lifting tons every day Rockwool is a world leading supplier of stone wool products and insulation systems. At their production site in Belgium, employees need to handle heavy metal parts used in the production process. And at the end of the production line, boxes of ready products are palletized at high speed. One pallet often contains 72 boxes, each box weighing around 25 kilos. That means one employee will lift a total of 1 800 kilo for each pallet they fill. To meet productivity targets> They need to finish at least four pallets in one shift, that’s more than 7 000 kilos. Handling this manually would obviously not be a sustainable solution. Looking for a solution to improve ergonomics and the overall workplace health and safety, Rockwool came across TAWI lifting solutions.

Verder launches new peristaltic hose pump - Verderflex Dura 65

PUMPS

The proven Verderflex Dura hose pump series has grown. The new Verderflex Dura 65 hose pump replaces the popular Verderflex VF65, boasting 20% more flow and 20% longer hose life. Thanks to the optimisation of the rotor, rotor shoe and the sliding surface of the hose, the new Verderflex Dura 65 achieves the highest flow rate on the pump market at this size. With a maximum flow rate of 33,000 litres/hour, it exceeds the performance of the previous VF 65 by 20%. Additionally, since the rotor requires fewer revolutions for this performance, the hose has fewer occlusions and therefore achieves a 20% longer hose service life. According to Darryl Macdougall, Managing Director, Verder Pumps South Africa, “The new Verderflex Dura 65 it’s much more than just a facelift to replace the Verderflex VF65. Our R&D team placed significant focus not only on the technical standpoint, but also what would make life easier, for both the owner and the user, when developing this pump.” The pump offers a seal-less and valveless, proportional flow rate. By incorporating the technical advances from the rest of the DURA range and increasing the utilised length of the hose so that the unit has a class-leading swept volume which enables the pump to achieve a maximum continuous flow rate of 22m3/hr. This puts the DURA 65 with a flow rate that matches existing pumps in the market, which are designated as '80' size, making the cost per flowrate with the Dura 65 better value for money. Additionally, the robust hose can be changed on-site. Verder has also made some modifications that ensure that servicing is more about ease, and reduced time rather than mess and complexity. There is now a filling nozzle for the 30

lubricant and a service access port on the front cover. To make the pump safer, a lifting point has been fitted on the front cover and a valve and hose tail has been added at the lubricant drain port so it will not spill all over the floor when emptying. There is an option for a level indicator, and max/min fluid sensors for the lubricant bath – so it can be connected and remotely monitored. This can also support hose failure monitoring.The smaller pump sizes of the Verderflex Dura are also available with an integrated frequency converter including potentiometer and installed hose breakage monitoring: the iDura launched in September 2020 is available for the Dura 5 - Dura 35. The iDura series can be controlled via 4-20 mA, Modbus® RTU, CANopen or Profibus via the inverter. Key features of the Dura 65: • The class-leading continuous flowrate of 22m3/hr • Greater utilisation of hose, so greater swept volume (higher flow/lower revolutions = longer hose life • The same reliable design of the Verderflex hose providing an

Raleigh Water takes a proactive approach to addressing pipeline risk by partnering with Xylem to conduct a probability of failure analysis of the entire network.

The City of Raleigh Public Utilities Department (Raleigh Water) maintains the water and wastewater infrastructure for 600,000 customers in Raleigh, North Carolina, and six surrounding communities. Raleigh's drinking water distribution system originally dates to 1887 with the construction of the City's first water treatment plant. The utility has documented several cast iron pipes installed as part of the original system throughout the heart of downtown Raleigh. Challenge Raleigh water had been an early adopter of data-driven approaches to assessing risk and prioritizing pipeline intervention based on existing industry best practices. Even so, with an extensive network of 3 765 km (2,340 miles) of pipeline comprised of more than 88,000 individual pipe segments, some of which date back more than 100 years, efficiently managing risk had become an increasingly difficult challenge. The utility determined that its current strategy was resulting invaluable time and energy being expended to replace assets prematurely while leaving higher-risk areas of the network in place. As part of a new, more proactive approach to addressing pipeline risk, Raleigh Water performed its analysis to determine the highest risk group of pipe segments in its network. Confident in the accuracy of its results, the utility determined that validation of this work would be a key component for selecting a partner to go deeper, by helping

Pipes, Pumps and Valves Africa - Sep/Oct 2021

Raleigh Water gain greater visibility into the condition of its pipelines, more accurately predict breaks, and optimize results to more efficiently prioritize its capital works. Solution In 2019, Raleigh Water partnered with Xylem’s team of industry and technical experts to conduct a probability of failure analysis of the utility’s entire network using Xylem Asset Performance Optimization services. Xylem combined historical pipeline break data with other infrastructure data from Raleigh Water’s Esri ArcGIS enterprise system – including pipeline location, size, length, and material – to generate risk levels for every pipe segment. Those risk levels were then applied to the distribution network layout within the utility’s Esri software to allow for additional analysis and planning. The data was then refined further through a clustering analysis which identified and prioritized 16 specific 1.5-mile sections of pipeline containing the greatest number of segments with a high probability of failure. Outcome Combining advanced risk analytics with Esri mapping software provided Raleigh Water with a more accurate, predictive, and targeted view of its network’s potential trouble spots than could be achieved through traditional identification methods. Xylem’s solution identified the top 1% of at-risk pipeline segments based on their probability

This gave Raleigh Water the confidence to not only move forward with its replacement plan for the original cluster but also begin prioritizing additional projects to address the remaining 15 high-risk clusters identified by Xylem. “Based on what we’ve seen with Xylem’s predictive modeling services, we are confident that replacing these mains is the best bang for the buck.”

Adam Haggerty, Asset Manager for Raleigh Water To date, Raleigh Water has planned six projects using the results of Xylem’s probability of failure and cluster analyses and continues to develop more efficient asset management strategies. It estimates the work with Xylem has already saved the utility up to five days of planning time (a 75% reduction) while reducing breaks across the network. Raleigh Water is also utilizing this increased understanding of its asset risk to guide the placement of sensors on key pipe segments. By monitoring water pressure and flow data within the high-risk clusters which have not yet been repaired or replaced, Raleigh Water is further reducing risk to its network, decreasing response times, and lessening the community impact of any breaks that may occur. This new data-driven risk model also helps support a citywide initiative to increase racial equity by ensuring there is no bias when selecting infrastructure projects. As one of the first utilities in North Carolina to use advanced risk analytics, Raleigh Water is proactively working on behalf of its customers – using data to achieve new levels of visibility into its network and drive asset intervention plans that are reducing breaks and increasing operational efficiency.

Clean in Place (CIP) process safety with the CombiLyz conductivity meter VALVES

The food and beverage industry is faced with continually rising quality standards, increasing cost pressure and strict hygienic regulations. As a result, requirements for processing systems and their efficient cleaning are growing. With an accuracy of 1 % and a measuring range of 500 μS/cm to 1000 mS/cm, together with fast and accurate temperature compensation, the innovative CombiLyz conductivity meter has the ideal technical properties to support CIP safely and cost-effectively. To guarantee food safety, production and filling facilities must be cleaned regularly. This is usually done using an automated CIP process (the cleaning of a process engineering system without dismantling it) and is part of a fully automated production process. In the food industry, the correct settings for a CIP process are very comprehensive, since the final CIP processes can often only be defined after the systems have been set up and meaningful tests have been carried out. There are as many requirements as there are cleaning programs. Some systems are cleaned with water only, while chemical cleaning agents like acidic or caustic solutions are used in others. Some systems recover the water from the last rinsing cycle and use it for the first rinsing cycle of the next CIP sequence to keep overall running costs low.

The exact concentration of cleaning agents, while taking into account flow rate, pressure, temperature and time, defines a reproducible process in which the CombiLyz clearly illustrates its superiority. While the concentration of the acid or alkali is increasing, the conductivity meter controls the specified concentration of the relevant cleaning media. With precise measurements, it ensures no more chemicals are used than necessary. This saves resources and protects the environment. During the phase separation in the CIP return flow, the CombiLyz with its good temperature compensation quickly recognizes different media, even when temperatures fluctuate enormously. This reduces the losses of stored cleaning agents. After one cleaning cycle, the CombiLyz accurately measures the concentration of the remaining chemicals in the rinse water. With this information, the PLC can control the predefined media circuits exactly and reliably using valve nodes. This reduces the risk of food

being contaminated by residual chemicals.

Thanks to its very user-friendly operation by touch screen and its modular housing, the CombiLyz is outstanding in its class. The conductivity meter is available with or without CombiView. This large, illuminated display can be rotated 360 ° and can thus be read easily from all directions, even from a great distance. It allows different view options, for example, the simultaneous display of conductivity and concentration values as well as fully customizable text (water, alkali or acid etc.). Alarms and configurations can be visualized on the device and can also be transmitted to the higher-level controller. With its integrated relay, the conductivity meter can carry out simple control tasks, for example in microbreweries with a low degree of automation, where food safety is of great importance and where valves are to be addressed directly without a process control system.

The same applies to retrofitting of systems being upgraded from manually controlled to partly automated processes. The CombiLyz sensor is available as a compact and as a separate version. The latter is available with cable lengths of 2.5 m, 5 m and 10 m. If required in the application, the display and the sensing element can be installed separately.

VALVES

Robust hygienic design and user-friendliness The robust sensing element of the meter is made completely of PEEK. To meet the requirements of different installations, it is available in lengths of 37 mm, 60 mm and 83 mm. Its compact design reduces the flow resistance in the line since the pipe cross-section is only minimally influenced. Deposits and impurities can be more easily transported out of the system. The hygienically designed sensing element itself can also be cleaned very easily, which is confirmed by the EHEDG certification and conformity with the 3-A standards. Furthermore, its design is exceedingly durable and is specially made for use in applications with frequent temperature shocks. This guarantees a long service life, reduces unnecessary downtime and thus increases system availability.

This offers maximum flexibility for optimum mounting positions. A wide range of adapters allows hygienic installation in most standard process connections. This makes it the ideal solution for many CIP systems. Baumer Group, sales@baumer.com, www.baumer.com

DFC extends SKG range with highpressure valve offering

VALVES

Dynamic Fluid Control, one of the world’s leading manufacturers, designers and distributors of high-performance valves used in mining, water and power generation sectors is pleased to announce the launch of the SKG-High Pressure series of slurry knife gate valves. Designed in house and manufactured at its Benoni plant using only locally sourced components, the valve is the pinnacle of the company’s localisation efforts. The SKG-HP was developed and refined in response to customer demand to solve problems typically experienced in harsh mining conditions where valve installations with lower pressure ratings are not sustainable. High-pressure valves are ideal in instances where the pipeline is required to accommodate larger volumes of media being transported. The valve is based on the same engineering principles as DFC’s current range of SKG valves with the exception that the new series can handle pressure over 700psi. It is designed for multiple high-pressure and high-cycle applications in environments exposed to abrasive, scaling and corrosive slurries, sludge, liquids and bulk solids. The SKG-HP can withstand maximum operating pressure of 740psi (51 bar) and its advantages include the low total cost of ownership, low maintenance and consistent, trouble-free operation.

The packing-less and robust design, heavy-duty construction and replaceable elastomer sleeves makes the SKG-HP ideal for applications where high abrasion resistance is needed. The valve’s compact design leaves no seat cavity for solids build-up that could potentially block full gate closure. Moreover, no metal part is in contact with the flowing media when the valve is in the fully open position. The design can accommodate manual, pneumatic, electric or hydraulic actuation for easy conversion in the field. Tumi Tsehlo, the CEO, says, “Although SKG-HP has been available for the past few months and installed in a number of mines across South America and in South Africa, we have chosen the Heritage Month to officially launch the product. South Africa has seen its traditional R&D leadership position eroded in recent years. We believe, however, that the country’s long industrial heritage is a major asset.” “We want to build on SA’s industrial legacy. Our sourcing strengths and over seven decades of manufacturing heritage should serve as a template to any firm willing to 38

The valve has been reinforced with stronger materials to withstand the pressure of mining slurries. This combined with bi-directional flow and shut-off reduces downstream leakage to negligible levels. The valve is also available in a version that is coated with Ziroflex, a hard chromium coating that not only improves wear and acid resistance but also has superior corrosion and heat resistance.

The SKG-HP is available in many configurations to easily meet customer-specific requirements, whether it be materials of construction, size of valve or actuation used to operate the valves.

VALVES

“As a global leader, we pay close attention to the challenges experienced by our customers. We are always looking to strengthen our portfolio to ensure we cover the complete spectrum of customer needs and applications in and through the sectors. With the high-pressure series we endeavour to make it easier for our customers to find the right valve for their needs,” says Tsehlo in conclusion.

contribute to the country’s re-emergence as an industrial powerhouse in the post Covid-19 era.” DFC has one of the largest installed bases of mineral processing valves in the world and manufacturing facilities in South Africa, Finland and the USA. It exports products to Australia, South America, Europe, Asia, the Middle East and Africa. The design of SKG-HP offers precise control over the flow as the valve when fully opened has two identical elastomer sleeves push against each other to form a cavity-free, bubble-tight seal to contain the line pressure. These sleeves are easily replaced without disassembling the valve. An integrally moulded encapsulated stiffener ring maintains the rounded shape of the sleeves under heavy shearing forces associated with high-pressure applications. SKG’s elastomer sleeves are designed to maximise rebound resilience and elastic recovery to improve abrasion resistance and sealing performance in mineral processing slurries. “We have proven this design through extensive validation to ensure it functions reliably and preserves operational integrity in the most critical applications,” adds Tsehlo.

Optimizing diaphragm performance INDUSTRY NEWS

This critical component in paint and coatings production can be challenging to handle, so the new Chem-Fuse Diaphragm from Wilden® will improve AODD pump protection. There is scarcely a painted surface in the world – be it a house, portrait or child's toy – that has not been covered by a paint containing titanium dioxide, or TiO2, which is a fine white powder that is produced most often through the mining of the mineral ilmenite. The reason that TiO2 is used as a white pigment in most of the world’s paints and coatings is simple: it possesses the highest refractive index of any material in the world. In other words, because TiO2 does not absorb visible light, any paint containing it has a high level of opacity, or hiding power, which is a needed characteristic for a high-performing paint or coating. Because of its indispensability as a paint and coating component, the global TiO2 market is a robust one, which is buoyed by the fact that it is also commonly used in the production of plastics, paper, pharmaceuticals, inks, food colourings and cosmetics, among many others. In fact, according to market-research firm Research And Markets and its “Global Titanium Dioxide (TiO2) Market 20192023” report, the TiO2 market will experience a compound annual growth rate (CAGR) of 4% through the year 2023. The size and importance of the global TiO2 market make it imperative that paint and coatings manufacturers identify and deploy a pumping technology that can reliably introduce it to the production process and then transfer the finished paints and coatings in the high volumes that are required to meet the demands of strict composition characteristics and production schedules. This white paper will illustrate how positive displacement air-operated double-diaphragm (AODD) pumps have risen to the fore as a first-choice technology for TiO2 pumping, with a new generation of diaphragm designs adding to their ability to deliver optimized TiO2-handling performance. The challenge In paint and coatings plants, TiO2 is introduced to the

Pipes, Pumps and Valves Africa - Sep/Oct 2021

production process as a high-viscosity slurry. AODD pumps have become an obvious choice for TiO2 transfer because they can handle abrasive liquids of higher viscosities that may also contain large solid particles. Their method of operation also gives them the ability to self-prime, deadhead and run dry with low shear, which enables them to quickly reach and maintain desired flow rates throughout the entire duration of the product run while also being able to reliably handle shear-sensitive materials. While AODD pumps can capably handle the general challenges of transferring TiO2, there is one specific challenge that must be overcome – through TiO2 appears to be a very fine powder, it is very abrasive in slurry form, which poses a threat to the longevity of the AODD pump's diaphragms. Specifically, the high level of abrasiveness of TiO2 slurry exacerbates a phenomenon known as "outer piston abrasion," which is a primary failure mode for AODD pumps. Outer piston abrasion happens with all standard diaphragm designs that rely on an inner and outer piston to hold the diaphragm in place. During its operation, the diaphragm flexes around the outer piston causing normal wear of the diaphragm at the point where they touch. Add a highly abrasive slurry-like TiO2 and the touching acts like sandpaper on the diaphragm, dramatically impacting its service life. This abrasion, if left unchecked, will cause the diaphragms to fail prematurely. The result of diaphragm failure is increased pump downtime, and higher maintenance, repair and replacement costs – and you can add cleanup costs to the equation if a product leak occurs. In these days where reliable throughput and product containment are at a premium as manufacturing facilities look to optimize their operating costs, any interruption in the production schedule, or costs associated with a

product leak, can be deleterious to the manufacturer’s bottom line.

While Wilden AODD Pumps have earned their stripes over the years as a go-to technology for TiO2 pumping, it is a recent advancement in diaphragm technology that further differentiates the pumps from the competition – the ChemFuse Diaphragm. The design of the Chem-Fuse diaphragm makes outerpiston abrasion irrelevant. Specifically, ChemFuse diaphragms feature an innovative one-piece Integral Piston Diaphragm (IPD) design that encases the outer piston within the diaphragm material itself. The elimination of the outer piston means that failure causing abrasion can no longer occur. Moreover, it also eliminates a potential leak point around the outer piston, further improving pump reliability. The result of this is that Chem-Fuse diaphragms can deliver dramatic improvement in service life when compared to traditional diaphragms that are used in AODD pumps that handle TiO2. The extension of service life in typical instances is usually two to three times that of

Conclusion It’s inherently obvious that the highest-performing paint and coatings feature titanium dioxide in their ingredient mix. It is also becoming increasingly obvious that Wilden Pro-Flo SHIFT AODD Pumps featuring Chem-Fuse IPDs are the best choice to optimize the handling and transfer of TiO2. Because of its high abrasiveness nature, TiO2 can put traditional two-piece diaphragms under extreme stress, leading to costly leak points, failure and downtime. ChemFuse diaphragms solve this conundrum through their integral-piston design, which eliminates abrasion points, leading to a safer, cleaner, more reliable and more efficient pumping process. By extending diaphragm service life, Chem-Fuse allows for unprecedented optimization of TiO2based paint and coating production.

INDUSTRY NEWS

The solution In the realm of AODD pumps, Wilden® AODD Pumps, the operating principle of which was invented by Jim Wilden 65 years ago, has long set the standard in efficient, effective and safe TiO2 pumping. Today, Wilden offers a full range of diaphragm pumps that are ideally equipped for use in paint and coatings production.

old-school diaphragms, though Chem-Fuse life spans that can be up to 10 times more than normal have also been observed. Finally, the encapsulation of the outer piston in the diaphragm material allows Chem-Fuse diaphragms to handle higher inlet pressures than standard two-piece diaphragms. This performance improvement makes the Chem-Fuse diaphragm unparalleled for use in difficult applications like TiO2 pumping. Chem-Fuse diaphragms are constructed of Wil-Flex™, which makes them 50% less expensive than laminated models. They can also be used in all Pro-Flo and ProFlo SHIFT Series 1" to 3" plastic and metal pumps from Wilden, which allows them to fit into any application.
