Sulzer sheds light on equipment maintenance with OEMs

Plant owners are increasingly opting to outsource the major elements of equipment maintenance to Original Equipment Manufacturers (OEMs) in an attempt to improve reliability and limit downtime. Pipes, Pumps and Valves Africa spoke to the team at Sulzer, a leader in pump design and manufacture, to find out more.

David Landsberg - Head of Service

Richard Morris - Segment Manager

There is no disputing that time is money. No matter what the industry, around the world operators are under pressure to reduce unexpected down-time of equipment, increase the lifecycle and perform more effectively. According to David Landsberg, Sulzer Head of Services, while many owners and operators in the past have preferred to take responsibility for the maintenance of their equipment or to outsource it to a third party, they are increasingly looking at retaining the OEM for the service and maintenance instead. “Accepting a long-term service agreement which involves all of the maintenance operations being completed by the OEM offers financial stability, technical expertise and continuous monitoring and diagnostics of their equipment.” Also considering the tough local economic environment most of industry are not investing any new capital into existing plants, he says, but rather maintaining output to weather the storm. “The local market are more and more opting to invest in its existing company equipment extend the life cycle to the maximum and with that has come a return to the OEM influence to maintenance.” Robert Blignaut, Head of Sales, says not only do OEMs 4

Robert Blignaut - Head of Sales

have the in-depth knowledge and technical expertise to maintain equipment optimally, but they also have the experience. “Proper installation is critical if pump reliability is to be achieved. Furthermore operator knowledge and process control are necessary to maximize pump life,” he says. “With the OEM responsible for the service and maintenance of the equipment this is monitored closely and it becomes far more of a pro-active approach instead of being re-active.” Whether it is avoiding improper pump operation such as system upsets, the loss of suction pressure, or even just running at less than minimum flow, high bearing or oil temperature, or improper starts and stops by opting for Sulzer’s full-service team pump downtime is reduced. Not only does it assist with operation training on site, but operation expectancy of the pump equipment is met. According to Richard Morris, Segment Manager Retrofits, the ongoing evolving of technology is another reason to consider using the OEM for maintenance and servicing instead. “The ever-increasing demands of industry has led to OEM investing in ongoing research and development. “The OEM has the ability to increase the efficiency of a pump by


introducing the new technology that we have access to.” It also keeps the equipment to OEM standards at all times which does reduce the overall cost of ownership over a period of time. “As the reliability of the pump increases, the operational expenditure decreases,” he explains. These maintenance and service contracts also hold the added benefit of extended warrantees for the equipment, says Blignaut. “Improving the maintenance process requires much planning, not only in terms of the capacity to do the work, but also to have the right parts available at the right time.”

says Landsberg. “These facilities truly ensure maximum efficiency in delivering high-quality repairs with minimal downtime. It is about being faster, more responsive and closer to our customers.” Ultimately, he says, by choosing Sulzer as maintenance partner equipment owners can improv their project management, repairs become more cost effective, productivity is improved, all while providing a far more fixed cost. The satellite workshops are supported from the main centre in Johannesburg. Opting to retrofit

Sulzer’s bespoke approach allows them to plan with clients what exactly the requirements and needs are including where stock is kept in the supply chain be it the OEM or the customer themselves.

Sulzer are advising clients to consider retrofitting pumps. “That does not mean removing it to replace it with a new one, but rather to upgrade components of the pump and improve the efficiency,” says Morris.

“The aim is to implement strategies for clients that reduce disruption and return a plant to normal operation as soon as possible,” he says.

This involves a site visit to understand the operational requirements. “The aim is to not interfere too much with the installation of the pump and to not make the process too complex. The goal is really to upgrade the pump and increase its lifespan as cost effectively as possible.”

Adds Landsberg, “We always consider the total cost of maintenance of a plant before making offering a costeffective solution to client. This approach starts with the sale of a piece of equipment ensuring clients understand what they can do from a total life cycle management point of view.”

He says this evaluation – and subsequent upgrade of the pump - allows the Sulzer team to come up with the best solutions for the plant owner to ensure that their service requirements are met in the most efficient way possible.

Faster delivery In an effort to meet client needs faster and more efficiently Sulzer have opted to open several field service workshops around the country. Situated in George, Durban, Lephalale, Kakamas and Welkom these workshops are equipped with the necessary lift capacity, repair technologies and equipment to help provide fast-paced, turnkey repairs. “Not only do we have a much shorter response time to clients, but it also allows clients in rural and remote areas to access a much wider range of services from Sulzer,”

Public, private sector must collaborate in the face of Joburg water crisis With the ongoing heatwave pushing water consumption to a record high, the City of Johannesburg has implemented Stage 2 water restrictions. The situation is exacerbated by falling dam levels due to low rainfall, and a planned shutdown of the Lesotho Highlands Water Project (LHWP) tunnel system for inspection and maintenance.

Infrastructure delivery company AECOM has extensive expertise in water resource management; conveyance, reservoirs and distribution; dams and hydropower; water and wastewater treatment; and water resilience and security. Its experience includes planning, designing, and managing clients’ water resources. Here it provides modelling, mapping, engineering, and scientific investigation. AECOM is highly knowledgeable in watershed planning and management, water rights studies, analysis of alternative supply sources, and the development of water supplies, raw water conveyance, conjunctive use, and related issues. Its specialists analyse the impact of potential strategies, ranging from ecological to regulatory and socio-economic, as well as from the standpoint of engineering feasibility. By applying adaptive management principles in the planning and design process, AECOM integrates science and management, delivering the most targeted solution possible. For example, it was approached by various private companies to provide professional services to improve their resilience in response to water-supply interruptions during the so-called ‘Day Zero’ crisis in October 2017, when the

City of Cape Town predicted it would effectively run out of water by March 2018. “We need to educate the people. Cape Town had a water crisis, from which its experience and successes must be shared, and the public made aware of,” Hanine van Deventer (Pr Eng), Senior Engineer, Water, Africa at AECOM comments. “It is a case where public and private entities need to collaborate to better manage water, a precious commodity, and serve the ever-growing population to promote economic growth.” Private property owners can become more resilient against water-stress conditions by reviewing their commercial and insurance obligations in terms of maintaining water supply; reducing their overall water dependency and consumption; familiarising themselves with the national and provincial legislation, regulations, and restrictions in terms of water use, and the development of alternative water sources and systems; engaging with their local Water Service Authority (WSA) on the local application and management of the national mandates according to local bylaws, restrictions, and standards; and even considering local private-public

Pipes, Pumps and Valves Africa - Nov/Dec 2019

partnerships in developing alternative water sources. “Early stakeholder engagement can clarify many uncertainties, and expedite procedures to establish a realistic and viable resilience plan,” van Deventer argues. WSAs must review the security, contribution, and sensitivity of their water resources respective to drought conditions. Importantly, this includes pollution-control measures in terms of acid mine drainage, wastewater, and poorlytreated effluent.

“It is a fact that South Africa is a water-scarce country. We need to evolve accordingly and manage water wisely. Everyone must work together to improve our state of water resilience,” van Deventer concludes. A registered professional civil engineer with 15 years’ experience in the civil engineering industry, she manages water projects for AECOM.

Ease-of-access to all legislative regulations that govern and facilitate water use for end users is vital. Here WSAs need to provide appropriate guidelines to ensure that technical and public leaders have a good understanding to enable them to direct and facilitate any queries. Bylaws must be sufficiently flexible for the needs of the private sector, including well-defined emergency conditions that may have to be accommodated.


WSAs also need to have a realistic water resiliency plan that needs to be communicated properly to the public to facilitate its implementation. The capability and readiness of bulk water infrastructure to operate intermittently at reduced flows and/or pressures must be assessed, in hand with contingency plans and interventions to reduce or control non-revenue water.

Cash flow and commercial strategy for water restrictions must also be implemented, as the revenue stream for WSAs dries up when the water supply reduces. However, overheads and maintenance costs could increase potentially. Here options for public-private partnership opportunities within stakeholder forums can be considered. Bulk water users can be given incentives to increase their resiliency and reduce their dependency on WSAs during water-stress times.

The responsibilities, delegation of authority, and decisionmaking forums in the national, provincial, and managerial governance environment under which all WSAs operate must be clearly defined and understood, to avoid any conflicts in attending to water management issues during water-stress periods. These forums should be vertically and horizontally aligned to adjacent and related governance and management structures – such as environmental, procurement, agriculture, and sanitation, among others. WSAs have to reach out and educate the various endusers in different spheres such as industrial, commercial and retail, government entities, and schools. They must facilitate stakeholder forums and partner with end-users in developing their water resiliency measures. Here different media can be used to keep the public and end-users up-todate, such as social media platforms and radio campaigns.

Innovative pump technology offers operational and water savings to mines PUMPS

While gross domestic product (GDP) gains from mining in South Africa decreased slightly to R227 291.33 in Q4-18 (from R229 490.48 for Q3-18), the sector remains a key economic contributor in the country. However, the sector is facing one of the toughest operating environments, to date; with revolving regulatory changes, geopolitical, civil and social pressures. Added to this, with growing water scarcity across the country, the impact of mining on the natural environment – and in particular around water use and management – are at the forefront of sustainability discussions within energy and mining resource industries. At the core of its operations; mining is about turning base ore into a purified mineral – and at profit. There are two distinct phases in this process: extraction of the ore from the orebody and concentration of the recovered ore into the desired mineral. The use of water has always been fundamental to the processing operation. Where often the demands for process water result in additional investment in water treatment and re-processing facilities, further increasing the initial cost of any projects – not to mention the resulting impact on the natural environment. However, in both phases, using novel techniques, focusing on the efficiency and the associated operational costs will yield the optimum return for the miner. For instance, emerging technology - like peristaltic or hose pumps – can significantly contribute to enhancing returns in processing operations where the crushed ore is turned into slurry (by adding water) and the slurry is treated and filtered to liberate the precious mineral from the valueless waste (or gangue). The same technology also has benefits in eliminating or reducing some of the consequential negative impacts from mining. Peristaltic pumping technology is an emerging technology that has evolved from familiar lower pressure, low flow medical devices into heavy duty, medium pressure industrial pumping solutions. These mimic the well proven principle of peristalsis found in the human body. Hose pumps are an essentially simple technology, using a specially designed, re-enforced rubber hose that is repeatedly compressed by a rotating pressing shoe and then allowed to relax, or respite. This action results in a simple positive displacement pumping mechanism with a powerful, high vacuum suction, dry priming action. Hose pumps have a number of attractions for process industries including a gentle pumping action, ability to pump high specific gravity (SG) liquids with significant solid contents, dry running capabilities, low in-situ infrequent maintenance requirements allied to abrasion resistance to provide an innovative solution to mining pumping problems. Specifically, by allowing higher SG slurries to be pumped, a hose pump can reduce process 10

water needs and deliver significant water savings. This innovative technology offers a number of advantages for mining applications, including that these pumps; • Are cost effective and require less initial investment, as well as less overall maintenance costs and downtime – providing mines a higher return on capital and easier operations • Promote the use of less water, as pumps can save (dilution) water • Use less space and power, than other conventional pumps • Pose less risk of chemical leakages, by eliminating leaking seals, which also means there is less chemical waste or damage and thereby less pollution and waste impacting the natural environment As Government, industries and society increasingly recognise the importance of and advocate for the sustainable management of resources – and especially freshwater resources - we applaud the existing efforts by mines to reduce their reliance on water and encourage them to seek out solutions that apply support to their endeavours in every phase of their activities. Solutions that can promise a reduction in water, space and power use, chemical waste, leakage and pollution, as well as risk – while reducing capital investment and thereby increasing overall project returnon-investment. These are the types of solutions that are worth investing in, don’t you think? Verder Pumps, +27 (0) 11 704 7500, info@verder.co.za, www.verderliquids.com/za/en/

Vesconite Hilube performs in challenging Nile River conditions

A Turkish OEM that supplied a Nile River project with one of its pumps that had been fitted with Vesconite Hilube polymer components in late 2018 reports that the line shaft bushings continue to operate well.


The OEM uses Vesconite Hilube in many of its most challenging projects, and this is why it elected to use the polymer bushing material in a project to pump river water from the Nile River. The project is associated with abrasive water with a large proportion of sand particles, which hard-wearing Vesconite Hilube would be ideal for, says Vesconite Bearings technical sales representative Phillip de Villiers. Also, since Vesconite Hilube is chemically inert and does not react with mild acid or alkaline chemi-cals, it would be useful in the Nile which, while it has acceptable water quality, is known to be pol-luted with agricultural, industrial and household waste, he comments.

Becker relays cable theft detection & motor protection PUMPS

Becker Mining South Africa’s Proloc and ProBeck electronic protection and control relays have been designed for motor protection, as well as cable theft detection, in diverse industries, including mining and quarrying, electrification, municipalities, water and wastewater, chemical, petrochemical and general engineering. “Becker’s low voltage relays, with advanced technologies for dependable protection of electric motors used on pumps, fans, conveyors and compressors, can also be used as highly effective stand-alone cable protection systems, to guard against cable theft,” says Nico de Lange, Vice President: Operations & Systems, Becker Mining South Africa. “Becker relays are programmed to detect cable theft by identifying a change in impedance of cable up to 1 100 V connected to a motor or pump. “In the event of cable tampering, the unit sends an SMS, or activates an emergency alarm or siren. This system is capable of SCADA visualisation and is able to communicate relevant information to a control room via an existing PLC. “The Becker cable theft detection system, with real time and date, is able to log up to 1 400 events, providing critical information, including when the alarm was activated and how long it took for someone to respond. The system needs to be re-set at the location of the alarm in order to confirm response by security. When the re-set facility is activated, the unit logs the date and time of the response.” This protection system, which requires only 220 V or 110 V to power the unit, can also be used as stand-alone units to monitor cable without power. A battery back up facility for SMS communication provides power back-up for up to eight hours. Proloc and ProBeck electronic relays for motors (380 V, 400 V, 525 V, 950 V and 1100V – 3,3 kV and 6,6 kV) have features for thermal overload protection, earth insulation lockout, frozen or vacuum contact failure and earth leakage protection. Other use-selectable features include short

circuit, frequency and power factor measurement, as well as minimum load, over voltage and under voltage protection. Becker protection relays are also used to control pumps and motors based on water levels, valve position, temperature sensors, time of day and moisture content of the soil. 14

Pipes, Pumps and Valves Africa - Nov/Dec 2019

These devices, which are able to detect dry run in boreholes, tanks and dams, can be programmed to automatically restart pumps after a specified time or set level. An important advantage of this system is a door mounted infra-red link that enables a laptop, with Proloc software, to manage all settings and downloads, without having to open the panel door and expose personnel to dangerous live equipment. This safety feature is a critical requirement in the OHSA Act. (No special licenses are necessary for the software.)

Local is lekker


APE Pumps and Mather + Platt are more than just a leading name in the pump manufacturing industry. This proudly South African company is a true testament of local manufacturing capability, showcasing the resilience, tenacity and ability to find solutions in the most difficult conditions that the country is renowned for. Pipes, Pumps and Valves Africa spoke to GM John Montgomery.

Go to any business and they will tell you, 2019 has not been easy. Operating in extremely challenging economic times with a fluctuating currency and political uncertainty has been difficult across industries. Consumer and business confidence remains low. Also Montgomery says it has been a tough year and that 2020 might not necessarily bring much relief. “Manufacturing has been under pressure with more and more goods being imported. On top of that there are no new business developments. We need to create new developments and opportunities if we want to boost local production.” One can’t, however, help but think of the saying that tough times might not last, but tough people do, when looking at APE Pumps and Mather + Platt. Founded in 1952 it has been an innovator and leader in the pump engineering industry, not just standing the test of time, but going from strength to strength. “I have never retrenched any of our staff,” says Montgomery. “We continue to invest in research and development making sure we stay at the forefront of innovation and the market.” It is accompany where the focus has always been 16

Pipes, Pumps and Valves Africa - Nov/Dec 2019

on its employees. One of the only pump companies in the country that owns its own pattern shop and is registered for training apprentices in the pumping field, investment in its workforce is ongoing. “Training and development remains at the core of this business no matter how tough the operating environment,” says Montgomery. In addition to pattern and mould-makers it also trains apprentices for qualification as boilermakers, fitters and turners and several other trades. Proud to be South African Whilst the company is owned by India-based multinational pump manufacturer WPIL it is a local manufacturer through and through. “Our products are designed, cast and assembled in South Africa and we are 100% compliant,” says Montgomery. More so, nothing is imported for its manufacturing process. “If one is encouraging others to buy local it only makes sense that we do as well.” More so, local sourcing and manufacture delivers far quicker lead times to clients and it is cost effective as there are no shipping costs to factor in.

“Another challenge when buying internationally is that pump designs change and many companies do not keep the old patterns,” he says. “A pump is sold and a couple of years on a new impeller is needed, but the manufacturer no

longer has the pattern and no spares are available. A new design might be available, but that comes with a new pump meaning one has to retrofit the pipes from site, the base plates and instead of just a spare being replaced, one is suddenly dealing with a complex overhaul.” At APE Pumps and Mather + Platt designs and patterns are never thrown away. With one of the most comprehensive vaults in the country it still has every single design from the first day it opened its doors.

In May this year the group opted to become members of the Proudly South African brand – a move they say underscores their commitment to local industry. With 9.6-million unemployed South Africans manufacturing is arguably the biggest driver for economic growth and job creation.


“We have people asking for spares for pumps installed 40 or more years ago and we can give them exactly what they want because we designed and produced it then and still have the designs and patterns,” says Montgomery.

“Our people in this business is by far our greatest asset,” says Montgomery. “We are a close-knit team with a very solid approach.” Quality products Constant industry engagement has resulted in APE Pumps and Mather + Plat developing a range of products that meets the exact needs of its clients. “OEMs continue to invest in research and development,” says Montgomery. “It has enabled us to create products that meet requirements and needs in the field, while we have also developed the ability to purpose-build, customise and retrofit.” At the heart of all of this is a quality product. “Our products have stood the test of time. They meet the needs of the African landscape as they are robust and reliable. We don’t cut corners.” According to Montgomery there is a definite move back towards OEM products. “When economies are slow there is always a tendency to move towards the cheapest products, but the trend is definitely shifting back to the OEMs not just for the sale, but the installation and maintenance of the pump.” Not only does the company have the history of delivering quality products, but it has the inhouse experience, knowledge and capacity to deliver exceptional results. “Especially in the project sector our ability to deliver turnkey solutions is something we are very proud of. We are always finding innovative ways to improve performance and supply and reduce costs with advances techniques.” Ultimately, says Montgomery, it is about providing the right type of pump to industry, pumps that are efficient and reliable no matter where they are operating even in some of the most challenging pumping applications in the world.

The effects of harsh environment on equipment


Protecting equipment and machinery is crucial for any kind of harsh industrial environment where parts are often worn out by abrasion, erosion, chemical attack, corrosion, and mechanical damage. Protecting equipment against conditions that cause premature wear, fatigue and eventual failure can significantly reduce the expensive replacement of parts. Loren Nauss, Business Development Manager, Maintenance Chemicals at Henkel explains more.


Protecting equipment and machinery is crucial for any kind of harsh industrial environment where parts are often worn out by abrasion, erosion, chemical attack, corrosion, and mechanical damage. Protecting equipment against conditions that cause premature wear, fatigue and eventual failure can significantly reduce the expensive replacement of parts. Loren Nauss, Business Development Manager, Maintenance Chemicals at Henkel explains more. Not protecting equipment properly can be a costly exercise. More so, it impacts on the reliability of equipment and the safety thereof. According to Nauss coating plays a significant role in durability. “It is about ensuring that equipment works better and lasts longer,” he says. Before choosing a coating solution, Nauss advises pump operators to make sure they understand the features and benefits of wear, abrasion, and chemical resistant coating solutions. Knowing how to select the right product for the right equipment is just as important as the correct method of application. “Increasing harsh-environment equipment through proper coating selections increases the longevity and efficiency of your equipment. It also saves costs and increases profits. The solutions available can be used in everyday maintenance

practices to reduce and eliminate downtime.” Know what you are dealing with Pumps wear over time, says Nauss, and as they do critical tolerances are reduced. The pump becomes more inefficient and ultimately stops performing at premium levels requiring either new parts to be installed or sometimes even a brandnew pump. Coating, says Nauss, simply help protect against the damage caused by wear-prone applications. Equipment can suffer from several physical and mechanical problems,


“Wear is the loss of material of the surface of a solid body through contact and movement of a solid, liquid or gaseous opposing body,” he explains. “The most important wear mechanisms are abrasion, erosion and cavitation. Corrosion and chemical attack on metal surfaces accelerate the effect of the wear mechanism. Corrosion on the surface weakens the surface and allows that abrasion and erosion to happen even faster.” Nauss says abrasion can be two or three-component wear when solid surfaces act against each other with a load and a relative motion. Erosion is wearing due to mechanical interaction between the surface and gas or a fluid, while cavitation is a form of erosion causing the material to wear by the action of vapour bubbles in a very turbulent liquid and rapid changes in pressure. Preparation is important There is no denying the benefit of equipment reliability and longevity that coatings give, says Nauss. It remains one of the most effective ways to reduce the loss of equipment performance. These solutions are designed to be wear-resistant, reduce friction, protect against caustic or acidic materials and cleaning agents, as well as increase line efficiencies. But, says Nauss, it is not a matter of just painting a coating on. Surface preparation is critical. “Before applying a coating solution equipment must be cleaned and pre-treated. To achieve a properly prepared surface for durable repair and coating equipment must be free of contaminations, of loose particles and critical residues.” He says the goal is to create a surface that is conducive to boding this allows for the best adhesion and strength. According to Nauss after the first cleaning, it is advisable to do an abrasive blasting followed by another cleaning after which the first coat of solution should be applied. “It is often necessary to control the application environment to ensure that there is no contamination to the equipment after the cleaning, but before the coating solution going on.” He also advises that one should avoid condensing humidity during coating application. The coating solution says Nauss can be applied by brush or sprayed on. One can also use a roller if preferred. “We recommend that it is best to use a brushable grade as a primary coat for good surface contact.” He also advises that one makes sure to use the right solution for the correct surface engineering needs. “With a wide range of products available this is not difficult to do.” Advantages of coating According to Nauss protective coatings and compounds increase the reliability of worn parts by restoring them to a serviceable condition. Ultimately this increases a pumps efficiency factor and flow rate. “Also, the equipment is more reliable. Higher reliability of devices results in an increase in mean time between failure from four to six years.” Another benefit, he says, is that of saving time by minimizing downtime and extending part life.

“Downtimes are much shorter as parts are being repaired instead of replaced. There is also no complex equipment needed for these coatings that ultimately result in extended part life with excellent corrosion and wear protection.” Another benefit is reduced cost as coatings and compounds allow for less part replacement, but also increased equipment efficiency. Nauss says it is also more cost-effective a solution as it not only improves the performance of the pump thanks to the new condition also from a maintenance wme_quarter but page_ad_FINAL.pdf 1 2019/10/31 point 12:37 of view there are advantages due to coatings often requiring minimal maintenance.

Facts about spring loaded pressure relief valves VALVES

The safety of chemical plants to people and environment is of paramount importance. Overpressures can occur in liquid or gas systems of which the causes can be many things either in the system itself or by external factors.


Overpressures can occur in liquid or gas systems of which the causes can be many things either in the system itself or by external factors. Since there is a wide range of different types of chemicals in the chemical industry, some chemicals may not be discharged into the atmosphere due to their toxicity to the environment or to any form of life in the proximity. For environment-friendly chemicals such as air, water, among others, the pressure can be relieved directly into the atmosphere, whereas for toxic chemicals, a relieved chemical is directed to a designated location where it can be reused or destructed into other forms before going off to the atmosphere. The most simple and widely used type of pressure safety valve (PSV) is conventional spring loaded. There are other types such as pilot-operated and burst disc PSVs which are usually used for special relieving cases. How it works A spring loaded PSV uses a spring to establish the required set-point. It is mounted directly on the vessel or pipeline it is meant to protect. The PSV is set at a pressure higher than operating pressure. The margin between the set-pressure and operating pressure is sufficient to avoid unnecessary opening of the PSV. The PSV only opens as soon as the pressure in the system reaches the set-pressure of the valve. As soon as the overpressure is relieved from the system as a result of the medium exiting the system, the PSV recloses and the process continues normally. Usually, if there is a sufficient back pressure (at least 10% of the set-pressure for gases and 2,5% for liquids) in the location where the PSV relieves, an option of balanced bellows is considered, which happens to cancel the effect of back pressure during relief. Balanced bellows are also used when the medium to be relived is corrosive. This prevents a corrosive medium to reach the internal parts of the PSV which are responsible for its proper operation. Sizes and selection of the PSV The standard widely used for PSV sizing is API 520, which also covers selection and installation of PSV’s in the chemical industry. The main objective of the relief sizing calculation is basically to determine the required relief area of the PSV. Tai Milano’s smallest available size is 3/4” inlet and 1” outlet, with an orifice type D and the biggest size is 8” inlet and 10” outlet, with an orifice type T1. The set-pressure range for Tai Milano PSV’s is from 40 kPa to 400 kPa. The body material is mostly available carbon steel (A216WCB) and stainless steel (A351-CF8M). The valve trim (disc, Pipes, Pumps and Valves Africa - Nov/Dec 2019

nozzle and adjusting ring) are usually made of more special materials which are compatible to the medium. In order to ensure a proper operation of the valve, the tests are carried out on each valve: Hydrostatic pressure test on the nozzle, body and bonnet at ambient temperature and pressure of 1,5 times design pressure. Tightness test with air under water in accordance with API 527 standard. Energas Technologies, +27 (0) 11 397 6809, laetitia@energas.co.za, www.energas.co.za

Invincible Valves remains positive VALVES

Nothing gets the team at Invincible Valves down. Not the wait-and-see approach brought on by the election this year, nor the slow economy, the country’s large fiscal debt or the policy uncertainty. Here, when the going gets tough, the tough get going. And it starts with managing director Pam du Plessis. Pipes, Pumps and Valves Africa sat down with her to find out more. Right of the bat, Du Plessis admits 2019 has not been an easy year. “There has been a definite slow down and companies like ours have had to mitigate the risks in our business. As a whole the risk is much higher than ever before,” she says. Despite this Invincible Valves has continued to go from strength to strength. Du Plessis attributes it to the company culture that she says is intrinsic to its success. “It starts with me every day. Culture is not something on paper that we aspire to or try to get right. It is what drives this business. It is a matter of living the company’s culture,” she says. “When I walk through the doors in the morning I am here, I am present and I engage with employees on an equal footing. This is our business and we all work towards its success. We also all share in that success.” Research has proved productivity in companies with a healthy corporate culture increases. This is often attributed to the positive morale of workers in these establishments that translates into efficiencies and effectiveness. Du Plessis says it is vital that the company culture be authentic. Not only does it have to represent the needs and values of employees, but it needs to be consistent. “Transparency creates that consistency,” she says. “Culture is a choice. We choose to be transparent and allow our employees a certain amount of freedom. We do not operate in a cloak and dagger way, not even in disciplinary situations.” That does not mean that there is always agreement. Conversations can be robust and staff don’t always see eye to eye not with each other or with management. “But we are always honest and there is a deep sense of trust within the organisation. Driving that consistently is very important.” The culture is also not just about benefiting the company, explains Du Plessis. It takes the people, its greatest asset, into consideration all the time. Training and skills development along with personal development is integral in the company’s culture. “It is not my business, it is our business. That is our ethos and it guides our culture,” she says. With an in-house training centre as well as several external training providers, knowledge and skills transfer is of utmost importance. “At Invincible Valves, we train. We make sure our people are on the top of their game and are always able – if they


Pipes, Pumps and Valves Africa - Nov/Dec 2019

choose – to learn and be extended more.” Ultimately, says Du Plessis, it is about having a workplace where staff are happy and know they are valued. Tackling challenges Du Plessis has always considered a challenge as a positive. “If there is a challenge, then there is an opportunity. The goal is not to be overcome by the challenge, but to rather take the time and find the opportunity that it is presenting.” With the South African economy under pressure, the team have increasingly been focused on exports. Rather than worry about the lack of local sales, they chased business elsewhere and the increased export volumes tell their own story. “We have seen good growth in several African markets. Especially in Ghana, we have been very successful,” says Du Plessis. Having opened an agency growth is realised yearon-year, as is the agency in the DRC. “Our products are very well received in these markets and

there is increasing demand for our valves.” According to Du Plessis quality remains the critical element in the business. “There is trust in our product thanks to our strong track record that we have built over many decades in the industry,” she says. “We compete daily with companies importing products from the East for half the price. Despite that, we are managing to hold our own and we attribute that to the quality of our valves.”

This year Du Plessis was awarded the International Women’s Entrepreneurial Challenge (IWEC) award in New Delhi, India. The awards and accolades are a proud reflection of Invincible Valves, says Du Plessis. “As much as it is an award for what I am doing, it is also a showcase of whom I am doing it with.”


That does not mean the company does not import from the East. It’s a stringent quality test, however, ensures that what is on its books is the best the industry can get whether it is imported from elsewhere or manufactured in their own factory. “We go out and visit the foundries, we look at the manufacturing processes and we make sure that every supplier meets our standards before we make any commitment to take on a product.” Building relationships

In 2017 she received an award as part of the Enterprising Woman of the Year Awards in Fort Lauderdale in the United States and in 2018 she was named Africa’s Most Influential Businesswoman in the engineering sector.

Highly regarded by her peers Du Plessis is a firm believer in relationships with people – be it her staff, her suppliers or her customers. “There is no threshold that can ever be reached. We are always moving the goal post and that requires us to work on our relationships all the time whether they are existing or new.” This is no one-man (or woman) game, but rather solid relationships at play. Her innovative approach to what is arguably one of the most male-dominated industries has seen her win several awards.

Getting the job done Globalisation has made it possible for multinationals to mass-produce valves, sourcing parts from around the world in a bid to remain competitive. Unfortunately, global manufacturing operations are normally slow to react to aftersales service requests. In South Africa, this problem is exacerbated by the fact that many process plants are over 40 years old which means that the OEM may not even manufacture spare parts for the valves which are in service. In their quest to maximise profits, many valve companies have moved their manufacturing plants to countries in the East; detrimental to product safety and quality.

Enserve, as one of the leading valve reconditioning companies in South Africa, has risen to the challenge and successfully entered into agency agreements with 2 of the leading valve manufacturers in the USA and now offer their customers service with the following benefits: • Components and complete valves which are 100% interchangeable with most leading valve brands. • Quotations within 2 – 5 days. • Lead times of 10% to 50% of what the OEMs currently offer. • Prices 20% to 50% of what is currently being charged by the OEMs. • Replacement parts for valves that have long been discontinued. • Comfort in the knowledge that all forging, casting and machining is sourced in the USA and Canada. Enserve also offers a countrywide, one-stop control, safety and manual valve reconditioning service both on and off-site.

BMG Interapp Desponia & Bianca butterfly valves VALVES

BMG’s Fluid Technology division supplies and supports an extensive range of components for fluid technology systems and general industrial applications.


These products include valves, hydraulic hoses and fittings, accumulators, cylinders, heat exchangers, hydraulic motors and hydraulic plumbing, as well as pumps and reservoir accessories. Important valves in BMG’s portfolio include InterApp Bianca and Desponia butterfly valves, which are recommended for high efficiency and safe use in demanding industrial flow control applications. “Robust butterfly valves are designed for dependable shut-off and control of corrosive fluids, as well as highpurity applications,” says Willie Lamprecht, BMG’s Business Unit Manager, Fluid Technology Low Pressure. “Compact butterfly valves, with good flow characteristics and low maintenance requirements, are extremely versatile and ensure dependable operation, even in the toughest environments. “Unlike a ball valve, the discs of butterfly valves are always present in the passageway within the flow. This means a pressure drop is induced in the flow, regardless of the position of the valve. Ball valves should only be used for isolation, whereas butterfly valves can be safely used for isolation and control of flow. “An advantage of using quarter turn butterfly valves rather than any other type of valve, is the simple, wafer-shaped design, with fewer parts, for easy repair and minimal maintenance.” BMG’s InterApp Bianca centric butterfly valves, with durable PTFE liners, are built for long service-life and are suitable for aggressive and corrosive fluids and for applications where absolute purity is essential. These high-performance valves, which are available in sizes between DN 32 and DN 900, are manufactured with a ductile iron, carbon steel or Stainless Steel body, to suit the requirements of all industries. Bianca butterfly valves can

Pipes, Pumps and Valves Africa - Nov/Dec 2019

be individually configured by BMG to ensure dependable operation and optimum safety in specific applications. For example, FDA compliant Bianca valves (DN 50 – DN 200) with mirror-polished Stainless Steel discs and highpurity PTFE liners, ensure safety for the production of active pharmaceutical ingredients. Bianca valves with PFA-coated discs and PTFE liners are recommended for use in highly corrosive, chemical applications. Valves in this range, with specially-selected conductive disc and liner materials, also conform with the explosion protection directive ATEX 94/9EG, ensuring safe operation in explosive environments. Notable features of the Bianca series include a high liner collar, a PFA disc over-moulding on the shaft, as well as a life-time pre-loaded safety shaft sealing, ensure reliable primary and long-lasting secondary shaft sealing, even for


demanding operating cycles and at high temperatures. The chambered liner prevents cold flow at the flange sealing surface for increased service life and the PTFE liner, in combination with the PFA-overmoulded disc, ensures low friction, thus longer life of the system. Other features include an external shaft sealing mechanism to protect the valve neck hole and a robust self-lubricating and maintenance-free bushing. A Stainless Steel valve label enables full traceability. BMG stocks a wide range of semi-finished components to offer short delivery times, even on large sizes of the Bianca series up to DN 900. Typical applications for Bianca butterfly valves are in mining and slurries for the extraction of acids and solvents; for the processing of additives in the oil and gas sector and for highly corrosive processes in the steel industry. This series is also suitable for use in water treatment where the smallest impurities need to be avoided. BMG’s multi-purpose InterApp Desponia and Desponia Plus centric butterfly valves, with a tough body and robust elastomer liners, are designed for safe and reliable regulation of liquids and gases in diverse sectors. Desponia valves, which are available in sizes from DN 25 to DN 1600 and pressures up to 16 bar, are suitable for various industrial applications. This range can be supplied with a cast iron and ductile iron body. The Desponia Plus range comes in sizes between DN 25 and DN600, with high-pressure applications up to 20 bar and is

suitable for high-temperature or vacuum applications, as well as process automation. This range is available with a body made of ductile iron, cast iron or Stainless Steel. The liners and discs of this series play a crucial role in elastomer-lined butterfly valves, as they are the only two parts that are in contact with the fluid. FlucastŽ liners are suitable for abrasive applications and also meet FDA and EU regulations. Notable features of this range include an external shaft sealing mechanism which protects the valve neck hole and a long neck design that allows pipe insulation. A retaining washer offers blow-out protection and O-rings that are built in the shaft passage, form part of the reliable shaft sealing system. Sealing lips on the flange face offer perfect tightness and the optimised liner shape ensures a precise grip to the body. The square driven disc offers effective and durable torque transmission and polished disc edges minimise friction. The Desponia range ensures safe operation in water treatment processes, as well as in power generation and for demanding chemical processing applications. These valves can also withstand operation in the steel industry, where shut-off valves used to gas molten steel, are exposed to harsh conditions. These valves, with specially-coated discs, are also suitable for mining and slurries, for use in extraction processes which require valves with the highest abrasion and corrosion-resistance. BMG’s strategy to enhance its fluid technology services to meet growing market demand, encompasses the introduction of new products, with the latest developments in design technologies, materials and coatings. Fluid technology services also cover project engineering and consulting, cylinder design and manufacture, training, repair and testing, as well as on-site container services.

To Refurbish or not to refurbish


This is the question asked by many valve end users. Wayne Arnold, of Valve Hospital clears the much-asked question up.


“A company sitting with an old, worn out valve, has two choices”, Arnold says, “first choice, is to spend the money on buying a new valve, the second choice, on the other hand, is to refurbish the existing valve. Both choices, have the same end result, a fully functional “new” valve. However,” he attests, “the biggest difference, is the significant financial cost of buying a new valve versus a refurbished one”. Arnold goes on to say, “refurbished does not mean substandard, but is rather indicative of a quality-controlled remake of an existing valve that is returned to OEM standards with the same performance criteria as a new valve”. “It’s not just about the direct cost, there is more to it,” he says, “a refurbished valve in fact reduces the overall cost of ownership by reducing valve costs, lead time and improves downtime”. There is no waiting for stock to arrive, refurbishments offer a quick turnaround time, getting the plant up and running much quicker. Added to this, It is important to note that every refurbished valve is tested and issued with its own test certificate, whereas, new valves are simply tested through a sample test method, therefore a batch test certificate is supplied.

Consumers must educate themselves As a consumer, customers need to ensure that the valve refurbishment supplier they are using meets specified industry standards in order to ensure that the valve refurbishment is meets OEM requirements. Every valve must be tested to international standards such as API, ISO, BS and ANSI standards. Consumers must also ensure that the test pressure done is in accordance with the design rating of the valve rather than the working pressure of the valve. Valve Hospital Valve Hospital offers a complete refurbishment service on valves and pumps. Wayne’s philosophy and company mottos is “here, refurbishment approaches new”, indicating that their refurbishment service provides exactly the same warranties and guarantees as that of a new product. Valve Hospital, with full ISO accreditation, carries out essential equipment evaluations to ensure refurbishments meet the required OEM standards. With a comprehensive work instruction process, standardized work principals, full stripping and shot blasting capabilities and an extensive range of machine

tools, customers are reassured that Valve Hospital can turn any size valve from a “ready for scrap” item into a completely refurbished, “ready to use” product. Valve Hospital, Wayne Arnold, +27 (0) 11 421 8170, +27 (0) 83 703 1559, wayne@valvehospital.co.za

Rexus - making a difference through innovation VALVES

Rexus is one of the prominent local designers, manufacturers and suppliers of Valves, Couplings and Fittings for the Water and Wastewater industry.


Starting back in 2010, the company deliberately and diligently focussed on innovation, local manufacture and the development of an export market. Rexus’ first major success was in the acceptance of its patented AirFlo range of Variable Orifice air valves after vigorous 3rd party testing in 2012. The 2012 testing was followed in 2013 by the most comprehensive 3rd party performance and comparative testing ever conducted in the air valve industry. These tests allowed Rexus’ clients to confidently specify its valves and also assisted the company to grow its local presence and to establish a sound foothold in the African and Middle Eastern markets and develop a budding North American market. The AirFlo air valve design incorporates a Variable Orifice that automatically and infinitely controls the discharge of air thereby reducing the potential for surge and water hammer in pipelines. Thus the sole protection for the largest pipeline (in diameter) ever constructed in South Africa and, some of the largest pipelines commissioned in South Africa since 2012, is the AirFlo Variable Orifice technology. Rexus’ CheckFlo range of high-performance Nozzle Check, Silent Check and Tilting Disc non-return valves were developed in parallel with the AirFlo air valves as the two product ranges complement each other. These type of non-return valves also prevent surge and water hammer and; the Nozzle Check valve design also, reduces energy consumption and maintenance requirements. Currently, Rexus manufactures the largest range of both air valves and non-return (check) valves in South Africa in size, pressure rating and performance range. The traction gained by Rexus for its products in both the local and international market is based on the fact that Rexus meets and exceeds the most stringent performance and technical parameters. Further, Rexus provides the shortest

Pipes, Pumps and Valves Africa - Nov/Dec 2019


lead times in the industry. The company has for example delivered for export and in full compliance to all test and material requirement, air valves in sizes of up to DN300 and pressure rating of PN63 in less than three weeks and large diameter Nozzle Check Valves of up to DN900 in less than six weeks. Whilst Rexus is best known for its manufacture of valves, the company is also one of the largest suppliers of Ductile iron pipe, PVC and HDPE pipes and manufacturers of pipe fittings and couplings in South Africa. Rexus is the first coupling manufacturer to manufacture its complete range of couplings, flange adaptors and dismantling joints 100% locally. Built into their KII range of couplings are several innovations that allow for ease of installation and better sealing and performance in comparison to other designs. Rexus has built fit for purpose machinery to reduce the lead times of all its products. This foresight has often been the reason for Rexus being the first port of call for assisting municipalities and metropoles across the country to provide bespoke couplings for emergency pipe breaks as they are one of few if not the only entity that can provide virtually any bespoke coupling or flange adaptor of any size in less than 24 hours.

Longer wear life at Africa’s top copper operation


Kansanshi mine has significantly reduced costs and improved productivity by applying Weir Minerals’ Linatex® premium rubber lining solutions. Kansanshi, Africa’s largest copper mine, is located near Solwezi in Zambia. The mine site is very remote, so getting parts and replacement material to site is time consuming and costly. Of particular concern for the operation was excessive wear in the tailings lines, as well as the overflow tank in the continuous counter-current decantation (CCD) circuit. There is approximately 8km of tailings pipes running from the plant to the tailings dam. The mine had previously lined their pipes with a combination of HDPE liners and alumina ceramic tiles. These, however, only achieved a wear life of approximately nine months. Kansanshi approached Weir Minerals Africa for an alternative solution and the company, who has a longstanding relationship with the mine, specified Linatex® premium rubber to line the tailings pipeline. Known for its outstanding wet abrasion properties, Linatex® rubber also requires a considerably shorter time for lining installation when compared to alumina ceramic tiles. The lining was completed well within the allotted time, saving Kansanshi unnecessary and costly plant downtime. After 36 months in operation the Linatex® lining showed minimal signs of wear, and the installation has reduced the mine’s total ownership cost by over R1,6 million per annum. Kansanshi also needed a more cost effective wear solution for the overflow tank in the CCD circuit. This had previously been lined with alumina ceramic tiles, which only lasted

between 60 and 90 days. The tiles were wearing away quickly due to the high impact and abrasion of the stones and sand flowing through the tank. Washout between the tiles was preventing the tiles from adhering to the metal substrate and the subsequent damage to the tank required repair work. In response, the Weir Minerals team specified Linagard® nitrile-based rubber (NBR). The expected cost savings from the increased production and reduced maintenance offset the installation costs. Underpinning the company’s reputation for customer support, the Weir Minerals technical lining manager was on site for the duration of the tank re-lining to provide technical assistance to Kansanshi’s maintenance team. Since installation, the Linagard® NBR 30 has lasted 36 months without any visible signs of wear. This represents 18 times longer wear life than the previously installed alumina ceramic tiles and eliminated the need to repair the tank every two to three months. Kansanshi has experienced significantly reduced downtime and increased productivity since the installation of the Linatex® solutions, and mine maintenance personnel can focus on other areas of the mine. Combined the mine’s costs have been reduced by R10,4 million per annum with Weir Minerals’ Linatex® solutions. Weir Minerals Africa, rajen.govender@mail.weir, www.minerals.weir

BT Industrial is transforming the industrial landscape in South Africa PIPES

Built from start-up, BT Industrial – a new-generation, black-owned, high-energy business driven by innovation, international standards, and service excellence – is transforming the industrial landscape in South Africa.

As a manufacturer of HDPE pipes, BT Industrial conforms to the local content requirement of the new Mining Charter, meaning that every R1 spend translates into in a R1.28 Broad-Based Black Economic Empowerment (B-BBEE) benefit for its mining clients. “Our clients cite this as being crucial for their B-BBEE scores,” Founder and Managing Director Kgomotso Lekola comments. BT Industrial recently received a prestigious CEO Circle Entrepreneurs 2019 Award, awarded by a panel consisting of Discovery CEO Adrian Gore as Chairman, Investec CEO Fani Titi, Vodacom CEO Shameel Joosub, and Sasol CEO Bongani Ngqababa. It was selected as one of seven medium-sized black-owned and managed businesses, from an initial tally of 140, to be transformed into national champions over the next five years. The seven businesses selected currently all have revenues between R50 million and R100 million and will be nurtured over the next five years to have a value of over R500 million. Not only does BT Industrial manufacture its HDPE pipes to the highest standards, but its high-capacity plant in Roodekop, Germiston allows it to achieve unmatched production efficiencies. As a result, it can offer superior price-performance to its customers, which gives it a major competitive edge in the industry. In terms of track record, BT Industrial has executed several critical mining and infrastructure piping projects, and in all cases, it has outperformed expectations. BT Industrial is ISO 38

Pipes, Pumps and Valves Africa - Nov/Dec 2019

9001-accredited and is one of the very few manufacturers with SABS accreditation. It supplies HDPE pipes to the mining and oil and gas industries, power stations, process plants, and telecoms companies. Applications include freshwater and wastewater conveyance, water and chemicals used in industrial processes, petroleum products, and even fibre-optic ducting. Ancillary services include HDPE pipe design, installation and commissioning, quantity surveying and project management for the mining industry, engineering project management, and also the import and export of polymers, specialised machinery and chemicals. With innovation as its key driver, BT Industrial has developed an array of proprietary technologies in collaboration with top universities in the field of engineering. Its proprietary developments in piping systems and solutions include a unique solution to manage the problem of corrosion at pipe supports in process plants, statistically the most common cause of external piping failure due to corrosion. “Our solution allows plants to maximise their hours of operation while carrying out critical inspection and maintenance of corroded carbon steel pipes,” Lekola highlights. These are common components of steel-frame structures at most plants, where pipes are required to be supported on metal I-beams.

Apart from product and technology innovations, BT Industrial has also invested significantly in a sophisticated ERP system that will make it easier to scale-up its operations for future expansion. This gives it strict control over its production, from the raw materials inputted at the beginning to the rate of production, any issues on the production line, and the quantity of scrap that results. “Operationally this takes us to the next level, as we have a direct line of sight into our daily operations,” Lekola stresses. His involvement with the mining industry began with his acquisition and further strategic development of AfricaWeather, a leader in weather-risk management for the mining industry. Here the key value proposition was safety and work planning according to weather conditions using technology developed to track storms, monitor lightning strikes (cloudto-cloud and cloud-to-ground), and generating accurate bespoke seven- to 14-day forecasts based on the mine’s unique operational requirements. This paved the way to develop more technological solutions for mines, and hence BT Industrial was established. “This gave me direct exposure to the mining industry in terms of both its business risks and opportunities,” Lekola adds, who holds both a BSc and MBA.

Robots already replacing workers There is a technology that is disrupting the workplace, it’s called Robotic Process Automation (RPA). Using software ‘robots’ to mimic repetitive human interactions with computers, this technology can do these tasks much faster, without any rest and no errors that human are prone to making.

FIRtech Holdings COO Fanie Botha says although this technology is not brand new, the last two years have seen an unprecedented adoption by many companies where repetitive tasks are now being automated and performed by robots. “Many consider this a threat, but companies see it as a great opportunity to create new high-quality jobs that require human intelligence and creativity.” The tail-end of the third industrial revolution saw the introduction of mass industrial automation and robotics. The microprocessor revolutionised manufacturing and countries that embraced and adopted this revolutionary technology, were the beneficiaries of sustainable manufacturing industries. They still maintain a competitive advantage in the 21st century. Similarly, in this industrial revolution, businesses and countries that embrace and adopt 4IR technologies (including RPA) are going to be the global beneficiaries of agility, efficiency and cost. RPA has specifically been designed to streamline repetitive business tasks, increase accuracy, save time and reduce costs. These are the tedious manual repetitive tasks that don’t add any value to employee knowledge. “It’s not about removing people, but rather about using them for vital processes and tasks that require intelligence, imagination, contextualisation and creativity. These new jobs will also bring new 40

Pipes, Pumps and Valves Africa - Nov/Dec 2019

opportunities for learning and allow employees to develop themselves with more creative work elsewhere,” he explains. According to Gartner, finance departments can save thousands of hours of avoidable repetitive tasks and rework caused by human errors - simply by deploying RPA in their financial reporting processes. The survey found that the average amount of repetition and avoidable rework in accounting departments can take up to 30% of a full-time employee’s overall time. Examples of these “time-wasting tasks” include: • Navigating through accounting/ERP system screens

between value-adding activities

• Repetitive searching for financial information, copying and pasting values into reports •And even painstakingly trawling through hundreds of transactions to find mismatches which cause Balance Sheet imbalances For an organisation with about 40 full-time accounting staff, this equates to savings of 25,000 hours per year or put differently, about R6-million saving. The survey says those departments that have experimented with RPA in their reporting processes, have reported a series of additional benefits, from less staff time fixing mistakes and more time allocated to analysis and decision support work. RPA can already handle much more involved processes such as matching large volumes of transactions; certifying account reconciliations or even collecting and compiling complicated financial reports. Robots will arguably do a better job than human beings, they don’t need to take breaks and they don’t make mistakes that workers frequently do when tasks are prolonged and mundane. Botha says managers usually think that their staff can attend to both the repetitive tasks (such as compiling reports) and the value-adding tasks of interpreting them. “However, on closer inspection, it often becomes clear that staff struggle to even just get through the repetitive tasks and make a considerable amount of errors in the process.” “The other side of that coin is that Robots cannot, and should not, interpret the reports they have created. There will always be exceptions that do not follow the norm of the business process, which will still need the human workers to investigate and resolve,” he adds. IDC forecasts the worldwide RPA software market will grow at a 49.3% compound annual growth rate (CAGR) for 2017-2022 to reach US$3.7 billion, which is much faster than the overall cognitive and AI technologies markets that will represent a 37.3% CAGR during the same forecast period. RPA is defining the future of work, the rapid adoption of this technology is helping drive business outcomes such as improved customer experiences and improved service delivery. Outside the finance department, RPA

Other examples include customer on-boarding and account opening procedures that are simplified and accelerated with RPA. There are huge cost savings as a result of productivity improvements or even fraud detection with insurance and expense claims. In a world where KYC procedures are mandatory, these processes must be followed to the letter of the procedure and not just the spirit of the procedure. This typically happens in a high-volume customer environment that is managed exclusively by humans. IDC predicts that by 2024, half of structured, repeatable tasks will be automated and 20% of workers in knowledge-intensive tasks will have AI-infused software or other digitally connected technology as a ‘co-worker’.


• Tediously finding the correct codes to use and to prepare financial journals

reduces the time to resolve queries and complaints - it makes specific processes available 24x7 and ensures more efficient processing.

These kinds of statistics can understandably be worrying to individuals who can identify repetitive tasks as part of their normal daily jobs. There is a real need however to change this perception both on the part of people who implement RPA, as well as the companies and the individuals who are the receivers and benefactors of this technology. When spreadsheet applications were introduced, there were certainly some nervous accountants who saw this software as a real threat to their jobs. However, today every person working in finance or accounting use spreadsheet applications in almost every task they deal with. He says companies that resist automation, risk being left behind. “Their competitors can now create more efficient cost structures with RPA and also deliver better services and customer experiences. It is therefore no longer an option, companies need to start exploring the benefits of intelligent automation technologies.” “They also need to take stock of their future skills requirements and how to reskill and redeploy their staff to a more high level and rewarding tasks. More importantly, to create an environment that fosters innovation and human-machine collaboration,” he concludes. FIRtech, +27 (0) 82 451-5593, www.firtech.co.za

Three myths of lubrication that need busting

As specialists in lubrication reliability solutions, the team at Lubrication Engineers (LE) South Africa frequently comes up against myths relating to lubricants.

“People believe things or are taught things about oils and greases that are not necessarily true, and by implementing this bad advice or outdated practices, they risk compromising their equipment,” says Callum Ford, National Marketing Manager at LE South Africa. “We try to educate the market about the best practice to help raise the bar and fight misinformation.” These are the three most common myths the company comes up against: 1. The colour of a lubricant affects its efficacy “We often have people phoning us up and saying things like, ‘I want the red lubricant because it’s the best.’ In truth, the colour of a lubricant is normally something that is added as a marketing tactic or to differentiate it from other products – it has no bearing on the effectiveness of the lubricant itself,” says Ford. “The most important aspect of lubrication choice is selecting a product that is best suited for your particular application.” Ford explains that LE South Africa uses colour in its products to differentiate between product types. Edible lubricants are white; lithium-based lubricants are yellow; open-gear lubricants are purple and lubricants for cars and trucks (especially oils) are red. Some companies, on the other hand, will colour lubricants to match their brand colours. 2. Grease it until it leaks Ford says that this line of thinking holds that greasing machinery with more lubricant means you will have to reapply the product less often. However, overlubricating can create problems instead of resolving them. “Overgreasing equipment will mean the lubricant begins to work against itself, causing internal friction,” he explains. “This can lead to temperatures rising in the machine, seals collapsing, and even eventual equipment failure. 42

Pipes, Pumps and Valves Africa - Nov/Dec 2019

For optimal performance, you need the right lubricant applied at the right frequency and in the right dosage. This is why lubrication schedules are important, and why many companies are moving to single-point lubrication systems, which automatically dispense lubrication into machinery in optimal quantities at set intervals.” 3. Grease is a grease Not all greases are created equal. Some are the consistency of honey; others of peanut butter; still others of toffee. Naturally, these greases will behave differently. “When it comes to grease viscosity, there’s a scale created by the National Grease Lubricating Institute (NLGI) ranging from 000 to 6, representing very low to very high viscosity greases,” says Ford. “Equipment manufacturers will specify the NLGI grade required on the equipment. If it specifies NLGI 002 and you’re using NLGI 3, you’re going to run into problems, because the grease penetration is different.” Furthermore, even greases with the same NLGI rating will behave differently depending on the base and additives with which they are made. “For example, I use a test machine we call a ‘rat trap’ to show clients how two lubricants with the same NLGI grade react to the same force or pressure over time. The one lubricant disperses from the joint where it’s been applied much quicker than the other, loses its tackiness and heats up far more quickly. This is why we take the time to understand what the specific lubrication application is, and what a customer needs before we recommend a product. Each of our unique, proprietary additives has been designed to yield specific benefits.” Lubrication Engineers South Africa, +27 (0) 11 464 1735, info@lubricationengineers.co.za, www.lubricationengineers.co.za
