Rely Precision Castings: driving change with innovation and expertise

Fueled by its new shareholders and a bold strategic overhaul, Rely Precision Castings is set to redefine the manufacturing industry. The company is committed to cuttingedge technology, sustainable practices, and unparalleled quality and is ready to tackle new challenges and seize emerging opportunities. Pipes, Pumps and Valves Africa finds out more.

It has been a busy few months at Rely Precision Castings, a company that has operated since the 1950s. Renowned for producing high integrity precision castings producing highintegrity castings to exact specifications, it is a business that has stood the test of time.

This resilience has been proven once again as the company survived 14 months of business rescue, thanks to the unwavering support of its clients and suppliers. This challenging period culminated in a successful buyout by a consortium of successful investors. The takeover by the new group of shareholders has placed the casting company on a new trajectory course.

Remarkably, all of this was accomplished within an election year in South Africa, which is historically challenging for business.

“Over the past 12 months, there has been a lot of change at Rely, and we have managed to emerge stronger than ever,” says Giancarlo Carrozzo, Director of Strategy and Commercialisation. “The journey to date has reaffirmed our resilience and proven that even when faced with challenges, this company delivers quality and reliability to its customers.”

Rely is one of the three investment casting foundries in South Africa. Situated in Boksburg, Gauteng, the foundry was originally established as a sand casting facility in the fifties. In 1973, investment casting capabilities were added.

According to Ian Barratt-Gibson, Production Director, the company is the largest precision casting manufacturer in Africa and the Southern Hemisphere, in terms of weight thanks to its ability to cast anything weighing only a few grams up to castings of 84kg.

“We are ISO 9001: 2015 SHEQ accredited, and we specialise in manufacturing investment castings produced according to individual customer requirements. All grades of air-melted alloys, including steel, copper, nickel, cobalt, aluminium, stainlees steel and other non-ferrous metals are poured in our foundry.”

Delivering success

According to Carrozzo, following the takeover, the company has embarked on a market expansion drive. “Growing our footprint is at the top of the agenda. We have a strategy in place that will see us invest not only in our facilities and technology but also in our staff. Skills development is important, and we continue to invest heavily in training, making sure we have the best team on board to service our customers.”

The company services a wide variety of industries, including transport, logistics, mining, power generation, water and sanitation, and general engineering. Its goal is to be a leading manufacturer in South Africa and the continent and to expand to the United States and Europe.

According to Barratt-Gibson, much of the company’s strength lies in its investment casting capabilities. “The benefits of investment casting are well-documented,” he says. “Not only can it be used to cast various ferrous

and non-ferrous alloys, but the parts require minimal if any, machining after finishing. We also achieve excellent surface finishes and can produce highly complex designs. Additionally, we can incorporate intricate design features such as logos.

“While slightly more cost-intensive upfront, investment casting proves more cost-effective in the long run. Yet, many companies still don’t realise its benefits. This process begins with a wax pattern coated in a refractory ceramic material. After drying and hardening the ceramic coating, we melt out the wax, leaving an internal cavity shaped like the final product, after which we pour in the chosen material. Once solidified we knock off the casting and perform minor fettling to create the finished product,” he explains. “Investment casting produces precise components with minimal material waste and energy consumption, virtually eliminating the need for machining.

“Moreover, we can rapidly develop prototypes that don’t require the upfront cost of a die and manufacture any quantity of components—from just a few to thousands— as per customer requirements. Not only do we work with various air-melted alloys, but we meet international standards.”

Wealth of knowledge

While investment casting minimises the need for machining, Rely prides itself on its advanced range of service offerings including machining, painting, heat treatment and polishing. “Our team is highly trained and skilled, capable of delivering bespoke solutions that meet every customer’s needs,” says Carrozzo.

The in-depth knowledge of the investment casting process is complimented by the team’s extensive application

experience and above average metallurgical applications expertise.

“Our technical team boasts over 120 years of combined knowledge, supported by a collection of over 6000 dies in our foundry.”

Ongoing investments in skills and technology underscore Rely’s commitment to establishing the foundry as a worldclass facility. “Our processes are efficient and reliable,” Barratt-Gibson emphasises. “While it takes six to eight weeks to initiate production, once underway, customers can order any quantity of their product weekly. We are not limited by production capacity in terms of personnel or volume.”

Quality remains paramount at Rely, with everything in our foundry meets world-class standards. “Our facility’s scalability allows us to adjust output as needed,” adds Carrozzo, highlighting how this flexibility benefits customers by minimising stock requirements. “We collaborate closely with each customer, delivering tailored solutions that precisely meet their requirements rather than offering a one-size-fits-all approach.”

Carrozzo encourages clients to engage directly with the Rely team regarding their needs. “As a flexible business, our agile approach enables us to deliver solutions that align with the customer’s requirements.”

Seal-less pumps for reverse osmosis water treatment

Demand for effective water treatment points to reverse osmosis.

Water is an essential substance to sustain life and one of the most valuable resources a nation can possess. Most of what is available, however, is of little use in its natural state. Water seems readily obtainable since it covers more than 70 percent of the Earth’s surface, but clean, fresh drinking water comprises barely a fraction of all available water. In fact, 97.5 percent of the world’s water is saline. Of the remaining 2.5 percent, 70 percent is locked up in the polar ice caps, and 30 percent resides in underground aquifers.

Demand for fresh water increases steadily, and researchers including Surendra N. Kulshreshtha of the University of Saskatchewan predict that half the world’s population could face water vulnerability by 2025 [1]. It is no surprise that the United Nations devotes much attention to the issue of safe, fresh water, particularly in places that have been underserved in the past. The UN released a new report in March 2009, Water in a Changing World, which is the third in series.

Equally concerning is ensuring that harmful toxins and contaminants are removed from water that manufacturing processes release in the environment. Wastewater from factory production often has levels of chemicals, pharmaceutical byproducts and other pollutants that can pose a significant risk to human beings and other life. Water and other liquids can be filtered and purified in many ways. One of the most effective methods is simple and straightforward: reverse osmosis (RO) filtration.

Design Principle

In RO filtration, liquid is forced through a semi-permeable membrane at high pressure, producing purified liquid. The contaminants are concentrated in a portion of the liquid that does not pass through the membrane and are discharged in a reject stream. Efficient RO systems employ positive displacement diaphragm pumps with a seal-less design and high pressure capability to purify large volumes of water or liquid at a time. The seal-less principle is

appealing because of its design simplicity, low maintenance and operating efficiency. Bill Wanner, CEO of Wanner Engineering, Inc. (Minneapolis, Minn.), explained how this design simplicity makes these pumps easy to operate and inexpensive to maintain. A seal-less design “removes the most maintenance intensive element compared to many other type pumps,” he said. “This not only permits the pump to operate in severe environments such as chemical treatment, but allows it to run dry indefinitely without damage, thereby avoiding a situation where operator error causes an equipment breakdown.”

Wanner added that the relatively small footprint of these RO membrane pumps is a tremendous advantage in mobile water treatment systems, such as those used by emergency management teams, offshore oil platforms and even in submarines, where space is at a premium. Due to its unique design, the seal-less, high pressure pump boasts a far more compact package than can be achieved with other pump technologies, such as multistage centrifugal pumps.

Energy Consumption

Energy usage is a major factor in the operational cost of water purification systems, so companies and organizations that rely on water treatment are extremely conscious of efficiency. It is not only important to keep costs low, but electrical power is also extremely coveted in certain environments. Oil platforms, desert desalinization plants and mobile treatment facilities are prime examples of how remote locations rely on efficient energy usage.

Manufacturers are likewise under increasing pressure to find efficiencies in energy usage, not only from their accountants, but from the general public. Going “green” is not just sensible for the bottom line, but is also smart PR. “We engineered [our pump] to operate so that a customer can use a smaller, lower wattage motor to acquire the same treatment capacity as other, less efficient types of pumps,” said Wanner. Wanner points to a number of

case studies demonstrating energy savings. In one such example, a single 12 kW seal-less PD pump replaced a pair of multistage centrifugal pumps totalling more than 18 kW, but with the same pumping capacity. The total energy savings was more than 50,000 kWh/year. Proportionate savings were shown in smaller applications, as well.

Since the seal-less, high pressure pump for RO is a positive displacement system, the flow rate remains constant even as pressure increases. This reduces the cost-per-gallon of water, the critical measuring stick when gauging efficiency. To stretch efficiency further, many customers are now incorporating energy recovery devices as well.

Reliability and Longevity

Approximately 80 percent of typical pump maintenance, according to Wanner, involves the replacement of leaking seals and packing. A seal-less design is an advantage in maintenance and downtime. In addition, these high pressure RO pumps feature a hydraulically-balanced diaphragm, so they are capable of handling virtually all particulates. According to Wanner, the pumps can handle solids of up to 500 microns, while other pump types may require the expense of a filter to prevent particulates larger than 10 microns from damaging the pump.

“We always tell our customers our Hydra-Cell positive displacement pumps handle the really miserable fluids and abrasives that destroy other pumps,” he said. “Our design enables charged and dirty liquids to be processed without the need for fine filtration to protect the pump. This reduces maintenance and allows the pump to operate continuously at high pressure.”

Wanner notes that most of these RO pumps can operate at any pressure from less than 40 psi up to at least 1,000 psi, with some models capable of operating at up to 2,500 psi. By comparison, rotodynamic pumps need to be started with 750 psi of pressure to avoid damaging the pump. When compared to piston and plunger pumps, seal-less RO pumps offer total separation of the pumped liquid from the lubricating oil, extending the life of the oil by a factor of four and reducing breakdowns.

“Axial piston pumps internally driven by water need five microns of absolute fine filtration,” Wanner added. “The filters typically cost around $500, and the elements, which should be changed every 15 days, cost about $180 each,” he said. “Those maintenance costs add up quickly, and failure to maintain the filter means very costly breakdowns.”

Maintenance cost is not the only concern. When one pump goes down for maintenance, it reduces the overall

treatment capacity. This means that additional pumps are required in large treatment facilities for redundancy. In smaller applications, it means two pumps are required when one maintenance free pump would have sufficed.

Application Flexibility

Although we tend to associate RO with water desalinization plants, it is also being used for innumerable applications in industries worldwide:

• Treatment of wastewater streams from food plants and industrial plants

• Treatment of waste solvent streams from chemical and pharmaceutical plants

• Treatment of recycled water for reuse

• Treatment of water used in boiler feed applications to prolong system life and efficiency

• Treatment of final rinse water in carwashes and in cleaning processes to aid drying and improve final result

• Disaster management water purification

Since pump seals deteriorate in the presence of corrosive chemicals, a seal-less design is often considered a necessity in everything from normal to severe-duty applications.

The Tides of Need and Demand to Rise

As the need for fresh water continues to rise and more laws regulating the treatment of wastewater are enacted, the demand for economical, energy efficient water treatment will increase. Part of this trend, driven by the rising cost of fresh water is toward localized treatment plants and units. Given the significant advantages of reverse osmosis filtration, it is no surprise that Wanner predicts this market will grow by 68 percent during the next five years.

Sulzer brings motors back online and minimizes lost production

Carrying out routine maintenance can be a chore, but failing to complete regular checks on important pieces of machinery can result in unexpected downtime and lost productivity.

Sulzer’s service center in Colton, CA, recently completed an urgent repair on a 700 hp (522 kW) motor, caused by a failed bearing, that could have been easily avoided.

A minerals processing company in the USA relies on many large motors to power essential pieces of equipment such as water pumps, pulverizers and vacuum pumps. To minimize the spares inventory, they use similar motors where possible to minimize downtime.

Keeping spares on-hand

For example, seven pieces of equipment are powered by 700 hp medium voltage motors that are now around 20 years old. Aside from the essential spare parts, there is also a complete motor that is used to replace assets that are removed for overhauls every three or four years. However, some of the maintenance routines are a little sporadic.

Sulzer has regularly carried out planned maintenance and overhauls of rotating equipment for the minerals company, including the 700 hp motors, which are interchangeable between different applications. When one of the motors failed unexpectedly, it was removed from service and sent to Sulzer’s Colton Service Center for inspection and repair.

When the motor was disassembled, the inspection showed the drive-end bearing had overheated and failed, allowing the rotor to contact the stator, which damaged the windings in both the stator and the rotor as well as the bearing cap. The motor had been overhauled by Sulzer three years previous, so all the technical details of the asset were on record. This made ordering new windings much quicker, expediting the repair process.

Repeat failure

In the meantime, the rotor and stator were stripped out before checking for any defects in the laminations. In this case, some minor machining enabled any hot spots to be removed and the core loss tests achieved a satisfactory result. At the same time, a new bearing cap was manufactured in-house, ready for reassembly.

Gary Patton, Colton SC Manager, explains: “Under normal circumstances, the minerals company would have installed the spare motor and production would have continued unaffected. However, in this case, the spare had recently been shipped to us for repairs following a premature bearing failure, caused by a problem in the application”.

Unfortunately, in this case, the lamination stacks of the rotor and the stator could not be saved, so additional parts would be required, and this repair would have a longer lead time. This dual outage had a significant effect on the production volumes of the minerals processed, which dropped by 25 percent. It was essential that the latest failure was repaired as quickly as possible.

Saving a week in project time

Once the new coils were installed, along with new bearings and seals, the motor was reassembled and run on Sulzer’s in-house testbed before being returned to the customer. The expected project time was five weeks, but by expediting the coils and working two shifts, Sulzer was able to reduce this by a whole week.

Patton concludes: “On this site, we found that the vacuum pumps are located beneath another process, which means that the motor cooling ducts can become blocked with debris. Unless this is cleared regularly, the motor and bearings can start to overheat, as happened recently in this case. A simple maintenance process could have prevented repeated failures of these motors and saved time and money for the business.”

Industrial applications such as this need reliable equipment, but any repairs need to be of a high quality and delivered quickly, especially when productivity is reduced due to an equipment failure.

Sulzer has suggested the addition of a shelter for the motors to reduce the build-up of debris and enable the motors to operate reliably between planned overhauls. The addition of bearing temperature sensors could also alert maintenance staff to the issue before the bearing fails. In the meantime, Sulzer’s quick response and outstanding service has ensured that the motors have been returned to service at the earliest opportunity.

Flow switches for pump protection

“We recently introduced the FF type series flow switch which has applications specifically suited to the water, oils, gas, food and beverage sectors as well as in general industry where pump protection is required. Its 200-bar pressure and piston valve seat design makes it a unique flow switch for a variety of industry applications” says Jan Grobler, MD, Senseca SA.

The simple mechanical operating principle of the piston valve seat design is space-saving and can be used and installed economically for high unit counts. The design of the flow meter FF is practically maintenance-free across all applications.

The volume flow raises a piston (fitted with a magnet) out from a valve seat against a spring force. The stroke causes a change in the magnetic field, where a hermetically isolated Reed switch is actuated and an electrical signal is generated. With spring-assisted stabilisation of the piston, use in all installation positions is possible. The vertical positioning of the Reed switch, adjusted at the factory, enables recognition of flow rates from approx 2% to 60% of the recommended maximum volume.

Largest value selection

Jan says the Senseca FF Flow Switch offers the largest switching value selection as well as the widest housing spectrum with a valve seat design. It is a cost effective and low maintenance flow switch which delivers improved system safety. The FF flow switch series consists of housing sizes for nominal pipe widths from DN8 to DN50 and

freely selectable switching values from 0.41 l/m. The swift reaction times of less than 100ms supplies a rapid actuation time for applications. An additional highlight of the flow switch is the high switching value repeat accuracy with a minimal pressure loss of less than 0.1 bar.

High pressure cleaning

“The FF series of flow switches suit high pressure cleaning technology applications as they are available in various housing sizes and are in fact suitable for applications within any sector where water, oils and gas are processed” comments Jan.

The simplistic design of the piston valve seat reduces maintenance substantially making it a preferred choice for applications where flow measurement is required. The FF flow switch offers a space saving solution for high unit counts, high efficiency and has a tamper proof switching value offering high system safety.

Filtration

When applied in process water in industrial systems, frequent contamination situations arise due to sediments and other ordinary content in the water. The filtration is a recommended design feature. The FF flow switch enables horizontal flow through the housing where the vertical functional design is highly resistant to water contaminants. This results in the filtration efficiency of the overall system being supported delivering enhanced safety and functional reliability throughout the application.

“Your order, we adjust”

The flow switch FF can be ordered to meet specific customer requirements. There is no switching value drift with the FF flow monitor, an advantage in flow monitoring for heat exchangers in cleaning technology applications with hot water systems.

“You order, we adjust. Senseca assures you that your application runs exactly the way you want it to. Individual and tamper-proof. Many industrial applications will benefit from the flow switch FF series. It is uniquely flexible, highly accurate with low costings, making it a preferred choice for flow monitoring applications” Jan concludes.

It’s all a question of dose

A new stepper motor-driven pump improves the dosing of aggressive chemicals.

Gentle and low-pulsation dosing of aggressive chemicals without pressure peaks and with minimized dead time. This is made possible by MEMDOS SMART, a new type of stepper motor dosing pump that Lutz-Jesco will be presenting at Achema, the world’s leading trade fair for the process industry, held from 10 to 14 June 2024 (Hall 8, Stand K86). The Industry 4.0-compatible dosing pump can be operated as easily and reliably as a smartphone via its full-colour touch display.

What do wastewater treatment plants, power stations and car washes have in common? They all need to dose aggressive chemicals on a daily basis – wastewater treatment plants have to dose flocculants into the water, power stations have to dose rust inhibitors to their piping and car washes are required to dose detergents to their cleaning brushes. These substances are often introduced via dosing pumps equipped with a diaphragm in its dosing head. The backwards movement of the diaphragm generates negative pressure in the pump head, which draws liquid in. If it moves forwards, the fluid is expelled from the pump head.

It is a simple and reliable principle with just one downside: conventional models available on the market usually work with standard motors running at a constant speed that maintain equal diaphragm stroke times during priming and ejection. This is disadvantageous because fluid delivery stops during the vacuum generation phase. These constant interruptions not only reduce efficiency, but also lead to a phenomenon known as “pulsation”, which can cause pressure fluctuations in the lines that impair the accuracy of the dosing and, in the worst case, result in damage and outages. “Pump operators often have to buy expensive accessories such as pulsation dampers in order to manage this detrimental effect,” says Steffen Roth,

Head of Development at Lutz-Jesco GmbH. “An economical alternative that we will be presenting at Achema 2024 is our new generation of diaphragm dosing pumps called MEMDOS SMART.”

A stepper motor enables the gentle and low-pulsation dosing of aggressive chemicals

At the heart of the new diaphragm dosing pumps from Lutz-Jesco is a drive with a microprocessor-controlled stepper motor. Unlike standard motors, however, the motor can be run asynchronously. In other words, the dosing pump can operate at different speeds for the suction stroke and pressure stroke. This enables operation of the motor at a higher speed during suction, thereby creating negative pressure which draws in the fluid more quickly. The vacuum phase, a dead time with standard motors, is reduced to a minimum. After priming, the stepper motor can then operate at a slower speed to expel the fluid in a controlled and even manner without an abrupt increase in pressure. A slow mode is available for highly viscous media.

“The stepper motor enables an almost constant supply stream, which permits the gentle, low-pulsation dosing of aggressive chemicals without pressure peaks and with minimized dead time,” emphasizes Roth. The repetitive accuracy of the MEMDOS SMART series diaphragm pumps is +-1 per cent across the entire dosing range. “We are convinced that stepper motor-driven diaphragm dosing pumps will dominate the market for high-precision and reproducible industrial dosing applications.”

The MEMDOS SMART is available in eight performance levels, with delivery rates ranging from two litres per hour at a pressure of 20 bar up to 180 litres per hour at four bar. There are also four different versions to cover all market requirements.

Easy to install, Industry 4.0-compatible and as easy to operate as a smartphone via a touch display

Lutz-Jesco has designed the pumps of the MEMDOS SMART series to be so compact that they require minimal installation space and can be integrated into compact dosing systems. For example, the models with delivery rates of between two and 30 litres per hour are just 280 mm long, 130 mm wide and 220 mm high. The pumps have a removable base for quick wall mounting, thereby minimizing the installation effort. The fullcolour 3.5-inch touch display can be integrated into the right-hand, left-hand or rear side of the housing, depending on the version, thereby ensuring flexibility for different installation situations. A version is also available with a ring cable. “Users can mount the cable-connected displays of several pumps next to each other on the wall and control the devices centrally from a single location, thereby saving time” says Roth.

other market players. It makes for significantly faster and less error-prone pump control”. At the same time, users can integrate the devices into a higher-level control system via a BUS interface. “In the Industry 4.0 era, this enables seamless integration of the dosing pump into larger industrial automation systems. If desired, the pumps of the MEMDOS SMART series can even control the entire system with valves, sensors, flow meters and other dosing pumps.”

According to Roth, the operation itself is as intuitive as that of a smartphone. “Users can understand and perform all functions immediately without the need for operating instructions. This combination of a full-colour touch display with operation similar to a smartphone sets us apart from

The difference between RSV Gate valves and Wedge Gate valves

These valves are robust and usually have a long service life. But, they suffer some disadvantages:

• The valve is often over-tightened to ensure a good seal. This makes it difficult to reopen. If leverage poles are used to apply extra force the valve can be damaged.

• The groove in the bottom of the body traps dirt and can stop the valve from closing properly.

• Anti-corrosion coatings near the valve seats are prone to damage, leading to corrosion of the valve body.

The resilient seated gate valve (RSV) was designed to overcome these problems. The gate has a rubber coating which makes for a better seal without needing excessive force or a body seat.

Early RSVs weren’t as good as those available today. Manufacturing quality was poor and the rubber lining sometimes detached from the gates. Today the rubber lining is moulded to the gate at high temperature and pressure leading to an excellent long-term bond. Some manufacturers now offer replacement guarantees of up to 20 years.

The strong bond between the gate and rubber makes the RSV a good choice in scour applications where high velocities might have torn the rubber in the past.

The manufacturing process, and economies of scale, have made these valves both cheaper and more readily avaiable than wedge gate valves. Fusion Bonded Epoxy (FBE) coating applied to the body and bonnet resist corrosion.

Other benefits include:

• Better sealing performance.

• Lower opening and closing torque.

• Resilience to particles in the water. There is no groove at the bottom of the valve to trap dirt.

• Reduction in water hammer due to the rubber absorbing some of the impact of a pressure spike.

The stuff dreams are made of

The booming hydrogen market promises brilliant prospects for environmental protection and investments running into the billions. It will transform the electricity, heat, and mobility sectors, and permanently transform entire industries. Valves, actuators and automation are set to play a key role in this. The innovative components involved support the rapid growth of the H2 industry.

However, the hydrogen market is very demanding. Systems must be able to handle a wide range of pressures, and temperatures as low as minus 253 °C. The high explosiveness requires the highest standards of sealing.

In addition, H2 plant operators expect products from the valve industry that are designed for a long service life and require little maintenance.

The valve industry is also adapting to this: As the hydrogen market scales up, the systems become larger and the pressures involved increase – and thus the dimensions of the valves also change. There’s no doubt about it that companies are facing big challenges...

Solutions for the entire value chain

Challenges for which companies are already offering solutions – along the entire H2 value chain from generation by electrolysis, through storage, transport, and conversion, all the way to the end application. With highquality materials and special geometries, as well as digital and automated products, the valve industry is proving itself to be catalyst for the hydrogen revolution. Leak testing and material suitability tests assure the end user of the safety that is particularly important for H2 systems.

All of this will ensure that hydrogen becomes so much more than the stuff dreams are made of. You can discover the trends and highlights from the valve industry at VALVE WORLD EXPO from 3 to 5 December 2024 in Düsseldorf. www.valveworldexpo.com

Cathode Isolation Valve for fuel cell systems

Reliable sealing of the stack is a top priority for the safe operation of fuel cell systems. The new Cathode Isolation Valve (CIV) from Purem by Eberspaecher meets the strict requirements for seal-tightness and prevents premature aging.

The use of hydrogen as an energy carrier plays a major role in the decarbonization of industry and mobility. Depending on the application, hydrogen-based fuel cell systems are a sustainable operating alternative, for example, for heavy duty commercial vehicles, passenger cars or stationary applications. The heart of a fuel cell is the so-called stack, in which the chemical energy of hydrogen is converted directly into electrical energy through an electrochemical reaction. Balance of Plant components guarantee safe functioning and efficient operation. The special requirements include sealing the cathode path to prevent leakage and therefore premature aging.

Longer service life

The Cathode Isolation Valve (CIV) from Purem by Eberspaecher is used in the cathode air path of the fuel cell system. The reliable sealing concept hermetically isolates

the stack when the entire system is shut down, preventing premature stack wear and extending operating life. At the same time, the conditions inside the fuel cell remain constant, enabling faster restarts. A fail-safe function of the Cathode Isolation Valve guarantees that the fuel cell stack is closed quickly and reliably in the event of a fault within the system.

The component is also adapted to the specific installation spaces of fuel cell systems: Their compact dimensions and customer-specific connections allow them to be designed for different applications.

Advanced material design

With its expertise in the field of materials science, Purem by Eberspaecher has designed the CIV for the specific requirements. The product is made of special materials that are insensitive to hydrogen. Another focus is on the use of suitable alloys that are resistant to attack by ultrapure water, which is a by-product of the chemical reaction and can lead to corrosion of metals.

Continuous control

The electric actuator of the CIV allows the cover position to be continuously adjusted in order to individually regulate the mass flow and pressure within the fuel cell stack and thereby optimize operation. This additional functionality ensures lower counterpressure and has been developed in cooperation with experienced partners. When developing Balance of Plant components, the exhaust and acoustics specialist draws on its Clean Mobility experience in exhaust technology and utilizes synergies from valve development. The Cathode Isolation Valve was tested in close cooperation with existing customers in order to further develop the first sample components for rapid series production.

CCUS supporting clean energy transition

Carbon Capture, Utilization and Storage (CCUS) is the process of capturing carbon dioxide (CO2) formed during power generation and other industrial processes and storing it to avoid emission into the atmosphere.

In cases where it is not utilized at the capture site, the CO2 is compressed and transported for use in a range of applications such as conversion to fuels or chemicals, or injection into depleted oil and gas reservoirs, saline formations, or other geological reservoirs where the CO2 is trapped for permanent storage.

CO2 capture has the potential to grow from 40 Mt CO2 in 2021 to 1.8 Gt CO2 by 2030 and 7.6 Gt CO2 by 2050, according to the International Energy Agency (IEA).

Enza Civils’ crucial role in shaping SA’s infrastructure future

Enza Civils, a division of Enza Construction, is strategically positioning itself to play a pivotal role in addressing South Africa’s pressing infrastructure needs in the water, transport, and energy sectors.

As the country grapples with significant infrastructure challenges, Enza Civils stands at the forefront, ready to provide essential solutions. Coen Naicker, Divisional Director at Enza Construction, along with Civils Contracts Directors Riaz Cassoojee, Ian Ferguson, and new team member John Hopewell, shared key insights into the company’s future, outlining an optimistic long-term outlook.

Together, they provided a comprehensive overview of the civil engineering industry and Enza Civils’ strategic direction, highlighting the company’s readiness to tackle the nation’s infrastructure demands.

In the recent budget announcement, South African Finance Minister Enoch Godongwana committed R943.8 billion to public infrastructure over the next three years. T his investment is poised to rejuvenate and expand the nation’s infrastructure, with allocations of R486.1 billion from state-owned enterprises, R224.8 billion from provincial and national governments, and R213.8 billion from municipalities.

Key focus areas include energy, water and sanitation, transport, digital infrastructure, human settlements, and agriculture. The government’s strategy includes a transformative approach to infrastructure financing and delivery, emphasising public-private partnerships (PPP)

and innovative institutional frameworks to attract private investment. A consolidated entity will streamline the financing, preparation, and execution of large projects, collaborating directly with private financial institutions and various governmental bodies.

Building more than just roads – building a future

Founded with a mission to specialise in bulk earthworks, roadworks, and the installation of essential services such as water and sewerage, Enza Civils has spearheaded numerous large-scale infrastructure projects across South Africa. Under the leadership of Coen Naicker, who joined Enza in 2016, the division has experienced significant growth and diversification, positioning itself as a key player in the industry.

“South Africa’s infrastructure, energy and water challenges are well-documented,” says Coen. “There is quite a lot of concern in the industry about whether or not, as an industry in South Africa, we have the resources and capacity to execute the work that’s coming and the work that is already out there.”

Coen’s deep understanding of these challenges has guided Enza Civils to consistently surpass expectations, ensuring the company is ready to address the nation’s changing infrastructure demands. His strategic vision and dedication to quality have played a crucial role in the division’s

accomplishments, cementing Enza Civils’ reputation as a reliable partner in South Africa’s development efforts.

Tackling water challenges

Starting with the water challenges in South Africa, Coen discussed the ambitious Lesotho Highlands Water Project (LHWP), which involves the construction of the Polihali dam and the connecting tunnel to the Katse dam.

“The LHWP is a monumental endeavour, aiming to create a reservoir on the Senqu and Khubelu rivers to bolster South Africa’s water supply from the Katse Dam to the Integrated Vaal River System, serving Gauteng and its neighbouring regions,” he explains. “Given Lesotho’s limited resources for such a project, much of the needed expertise and materials must be sourced from South Africa and abroad, including Europe and China.”

As part of the LHWP, numerous bridges are being constructed to maintain road access, particularly where existing low-level bridges will be submerged once the Polihali Dam is operational. Among these, the Senqu Bridge project stands out, stretching 825 meters in length and reaching a height of 90 meters. Awarded in August 2022, the construction contract for this bridge was granted to the WRES joint venture (JV), consisting of Webuild S.p.A, a prominent Italian construction firm, in collaboration with South Africa’s Raubex Construction, Lesotho’s Sigma Construction, and Enza Construction.

Roads and infrastructure development

The imperative of maintaining and enhancing South Africa’s road network is widely recognised, with SANRAL embarking on numerous projects, including the upgrade of the N2 / N3 freeways in KZN. While some projects are already in progress, others are yet to be put out for tender.

In October 2016, seven construction sector companies entered into an agreement called the Voluntary Rebuilding Programme (VRP) to drive transformation in the industry.

This initiative entails mentoring and nurturing smaller contractors while contributing to a construction fund for socio-economic development, as part of an industry settlement agreement with the government.

Under the VRP, Raubex committed to mentoring two partners, one of which was Enza Civils, with the objective of helping them reach 25% of Raubex’s South African turnover.

Coen elaborates on the collaboration with Raubex, stating, “Through our partnership, we have successfully completed three road rehabilitation projects in Kimberley, the Bakwena Platinum Corridor Upgrade, which added 32km of carriageway, and the widening of the N4 bridge over the Crocodile River to accommodate a dual carriageway. Additionally, we undertook a 30km partial upgrade of the R23 national road near Standerton in Mpumalanga. This included the construction of 4km of dual carriageway, a pedestrian crossing, traffic circles, and the completion of six bridges and sections of the R23 highway, with the project being delivered on 26 April 2023.”

Riaz, Contracts Director for the project, notes, “Upon commencing work in 2021, we were advised that this project might face challenges due to community concerns. However, SANRAL’s protocol mandated the initial three months of the contract to engage with the community and establish liaison structures. We prioritised transparency and local resourcing wherever feasible, fostering a positive working relationship with the community.”

Future transportation

projects

Looking ahead, Enza Civils is poised to expand its footprint in the transportation sector. John Hopewell highlights the potential opportunities: “Over the next two to three years, we are considering re-entering the road space, depending on SANRAL’s awarding and releasing of tenders. We see huge opportunities in upcoming road projects issued by the KwaZulu-Natal Department of Transport.”

Additionally, Enza Civils is exploring partnerships for large contracts emerging from TRANSNET’s rail infrastructure projects and the Durban Ports Authority.

Large-scale construction in the energy sector

Riaz explains, “Among our significant energy-related endeavours is the second phase construction of the Combustion Waste Facility at Kusile Power Station, a venture secured through a joint venture with Grinaker LTA.”

“The facility spans over 1,080,900 square meters and comprises an HDPE-lined storage area for ash residue from the coal-fired boilers. Our contract encompasses the construction of access roads, drainage systems for both contaminated and clean water, as well as pollution control measures such as dams and drains, in addition to the storage dam.”

Renewable energy ventures

Through its partnership with Tractionel Enterprise, Enza Civils has entered the renewable energy space. Their collaboration is currently focused on the Ummbila Emoyeni Renewable Energy Project in Mpumalanga. Tractionel serves as the EPC contractor for grid connection, while Enza Civils takes charge of civil and building work for the main transmission station. Owned by Seriti Green,

Ummbila Emoyeni represents a commitment to sustainable wind turbine and solar energy solutions. Enza Civils is poised to solidify its position as Seriti Green’s preferred contractor for future projects, marking a significant step toward a greener, more sustainable future.

Growing capability and expertise

Looking ahead, Enza is strategically focusing on various areas of business development, particularly in the energy sector where Tractionel Enterprise plays a leading role. By leveraging Enza Civils’ expertise in engineering and construction, the company aims to excel in energy-related projects. Additionally, Enza is committed to enhancing its presence in the water infrastructure sector. The transportation sector remains another key focus, with a specific emphasis on road and rail projects.

Coen emphasises the value of the Voluntary Rebuilding Programme (VRP) partnership with Raubex, which has diversified Enza’s portfolio, enabling independent tendering for projects. With a CIDB grading of 9CE, Enza can now tender for projects of any size, although it remains prudent and open to joint ventures for larger endeavours.

Unearthing greater efficiency with AI in the African mining sector

The global mining industry is in a state of flux as unprecedented demand for resources clash with ongoing global economic volatility and geopolitical tensions, creating both immense challenges and opportunities.

From record-high gold prices to the stunning growth in renewables driving demand for minerals and the global transition to net-zero, the mining industry is currently in an era of intense reinvention and disruption.

Africa’s mining sector isn’t spared this volatility. The continent has more than half of the world’s reserves of platinum group metals and diamonds, and nearly half of manganese and cobalt reserves, both critical elements in the batteries powering the global transition to cleaner energy.

Searching for greater productivity

In the current business environment, mining companies are under intense pressure to increase efficiencies, reduce costs, and boost productivity.

Autonomous technologies have ushered in a broad range of economic benefits for the mining industry over the past decade. By leveraging automation to perform some of the more hazardous tasks, mining companies have minimised worker exposure to dangerous conditions and bolstered overall safety standards within their operations.

Recently, the emergence of digital technologies such as machine learning and artificial intelligence (AI) has introduced new gains in efficiency and productivity. One market estimate predicts that investment into AI by the mining sector will reach $7.264-billion by 2033, driven by a compound annual growth rate of 22.7%.

The ethics of AI in mining

While it’s undeniable that AI holds immense promise for the mining industry, the introduction of any new technology is typically accompanied by a number of ethical dilemmas.

In the context of mining, fears around AI range from the displacement of human labour by automation and the increased surveillance compromising data privacy and encroachments on autonomous decision-making.

One of the biggest fears of AI’s impact in the mining sector relates to the potential of the technology to displace workers by automating their job roles and essentially making them redundant. In the context of Africa, job fears will remain, especially considering the important historical role that the sector plays in employment creation, especially in markets such as South Africa.

There are also concerns over explainability, that is how AI decisions can be explained in a way that makes sense to human workers. For example, if AI is used in surveillance at mining sites to improve safety and security, questions may arise over how the algorithm determines which actions can be considered safety or security incidents.

Whilst AI has the potential to improve efficiency and safety in mining, its deployment introduces new risks that must be carefully managed. Mining companies, technology developers, and regulatory authorities must collaborate to

establish robust safety protocols, provide comprehensive training, and establish clear lines of accountability to mitigate the risks associated with AI use in mining operations.

Practical use cases

Despie the concerns, AI will unquestionably play a leading role in the mining sector’s success in the coming years. AI lends itself to a myriad of applications across the mining value chain, including:

Exploration

AI-driven prospecting mapping models are emerging that analyse geological, geochemical and geophysical data sets to pinpoint promising areas for mineral exploration. By amalgamating diverse data sources, these AI models can enhance the successful discovery of promising resource deposits.

Geotechnical monitoring

Geotechnical monitoring and analysis are crucial to ensuring ground stability and infrastructure stability at mining operations. Here, AI can be integrated with sensor networks to detect early signs of instability or failure, while predictive models can forecast ground behaviour and assess potential hazards. AI can also be applied to create detailed simulations of rock masses that can help guide the design of tunnels, underground layouts, and slope stability.

Mine planning & optimisation

AI technologies enable dynamic, data-driven decisionmaking to optimise mine plans and production schedules. Mining operations can leverage AI to predict performance

under various conditions, helping decision-makers identify optimal productivity strategies while minimising costs. Predictive maintenance systems can also optimise the performance of mining equipment, reducing downtime and improving overall operational efficiency.

Supply chain management

AI’s benefits extend beyond mining sites to bring improvements to supply chain management. Predictive inventory management leverages AI for a variety of tasks, including reducing inventory planning time, minimising costs, optimising repair schedules, and determining the optimal times for reorders. By using techniques such as time-series analysis and probabilistic modelling, mines can gain real-time visibility over their supply chain. This can help mining operations optimise their logistics operations, including transportation routes and distribution networks.

AI is a transformative force in the mining industry, introducing a broad range of innovative applications to solving complex challenges across various facets of modern mining operations. By embracing AI-driven innovation and collaboration, mining companies can pave the way for a more efficient, sustainable and responsible mining future.

Sigfox S.A. to enable South Africa move to smart water meters on 0G network

Sigfox SA, a robust and exceptionally low-power technology, was selected by the National Treasury as the network to underpin the new smart water meter ecosystem.

The tender, commonly known as “RT29” awarded to various System Integrators, will see existing meters adapted or replaced to become smart meters to improve revenue collection and service delivery. All the new meters will run on the nationwide Sigfox IoT network.

Greg Rood, CEO of Sigfox South Africa, says: “Water is a basic human right, and we are proud to be associated with provision of such essential services, supporting both revenue collections and provision. The fact that the National Treasury has entrusted Sigfox to monitor and support over 15,000,000 smart water meters in the country underlines how robust the technology is. We expect this to be a catalyst to further grow our local IoT and system integrator ecosystem.”

Rood explains that Sigfox was selected to support the smart water meters due to the extensive network coverage, robustness of the technology, low power consumption and the SLAs associated with Sigfox. Sigfox 0G is a preferred technology for utilities around the world, and has an established track record of supporting large commercial utility deployments in South Africa. The superior range and penetration of the advanced Sigfox ultra-narrowband (UNB) signal makes it the ideal connectivity choice to reach meters that are often installed in challenging environments.

“The Sigfox SA network already covers 91% of the South African population. Should there be a need to extend or densify the network, this can be achieved quickly and cost-

effectively,” he says.

Sigfox technology also overcomes potential power challenges – smart water meters typically lack access to external power and rely on batteries. Sigfox’s low power network technology – designed to support IoT at scale –means a device can run on the same battery for over 10 years.

Rood says: “The technology has an extremely low power reliance. The smart meter devices are sealed and waterproof, with batteries built in. Our devices will last for over 10 years at one reading a day, which far exceeds the three-year lifespan stipulated on the tender. Due to this extended lifespan, it’s practically an ‘install and forget’ scenario, which cuts costs and optimises resources. Sigfox’s benefits also include ease of installation, accuracy and reliability. And the fact that the network is independent means there is no reliance on Wi-Fi or fibre in the ground.”

He notes that Sigfox is the only mass coverage network underpinned by an SLA. “This enhances reliability and delivers unprecedented ROI for municipalities,” he says.

“The transition to smart meters supported by Sigfox SA will mean improved collections for municipalities, real-time and accurate billing for customers, and improved management of increasingly scarce water resources,” Rood says.

Getting value from smart water technologies

Smart water management will meet SA’s growing demands for cleaner and cheaper water.

Barcelona is a unique city, blending old monuments and cathedrals with a very modern and bustling metropolis. But it has a few things in common with South Africa’s towns and metros, notably a semi-arid climate with limited access to water. As water stresses increased, Barcelona’s authorities needed to make a plan—and they decided to use smart water technologies. The results have been incredible.

Smart tech to solve water challenges

Water providers across SA are struggling with growing demand, ageing infrastructure, and shifting weather patterns. Experts warn about water shortages as several major cities and towns have already implemented water restrictions. Meanwhile, major water infrastructure is breaking down in large metros such as Johannesburg and eThekwini, buckling under the dual strains of rapid population growth and underinvestment in maintenance. Though the situation looks increasingly dire, water utilities have a big opportunity. Innovation in engineering and digitisation has honed a range of smart water solutions that can help improve existing water systems without

massive replacements, giving sites time and space to scope their future improvements with the help of data-driven insights to improve efficiency, forecasting, and demand prediction.

“Smart water solutions have developed extraordinarily in the past twenty years,” says Chetan Mistry, Strategy and Marketing Manager at Xylem Africa. “They can deliver specific point solutions, large overhauls, or start collecting and analysing rich data for planning. One of the biggest advantages today is that you can tackle a specific problem with a smart solution, then use that investment to tackle the next problem. You can scale effort while keeping costs under control.”

Smart water technologies are fundamentally data-driven. They collect and leverage water performance data to improve results through better management and visibility. Examples include smart sensors that collect various data points, data analytics for planning and efficiency, predictive maintenance, integration of different infrastructures for improved performance, and comprehensive real-time visibility through interactive dashboards (accessible

anywhere via the cloud and an internet connection).

The ROI of Smart Water

These innovations have a lot to offer, and they are costeffective. But, like all infrastructure solutions, there are still investment concerns. What is the value, the return on investment, of a smart water solution? Utilities can jump into smart water systems only to get less return than expected. How can utilities invest in the right smart water technologies and start to get that momentum they can build on and modernise their sites?

The two crucial steps to realising healthy ROI from smart water are embracing a digital modernisation strategy and focusing on value beyond cost. Digital modernisation is neither a mere rip-and-replace strategy nor as simple as installing and linking a few sensors to software. To get good results, the vision must be more specific.

“Water sites already use technologies; they have sensors and software,” says Mistry. “Smart water systems take things to the next level because they enhance what you already have and introduce new methods and insights. This means you rely only on a technical or cost mindset. You should choose smart solutions that work for a site’s strengths and enhance the site’s requirements. Start with a plan, a vision, for the site, then look for specific opportunities to apply smart water solutions.”

For example, a site might already generate useful data, but the overall management tools are isolated. Collecting information requires considerable time before one can predict consumption levels or maintenance demands. In this case, water managers can unify water operations

through cloud platform dashboards that securely consume the data, analyse results, and deliver single-truth insights to authorised personnel wherever they are—on-site, at the office, or even on the road.

Modernisation with a plan delivers results

A municipality could recoup costs by reducing non-revenue water. To do so, they can use smart flow systems to measure water allocation and consumption, identifying where there are losses. They can employ smart leak detection to pinpoint problem areas without shutting down the water pipelines for inspections.

Every site has unique needs and priorities. Smart water succeeds when there is a mindset for modernisation and a strategy to support that vision. These needn’t be massive projects—there are many low-hanging fruits that water utilities can exploit to see quick gains.

With the right planning and partners, smart water delivers great returns on investment. Barcelona reduced overall water usage by a massive 25 percent while still finding more revenue through optimisation, cost savings, and better service to customers.

All of this was accomplished by adding smart technologies to the city’s sprawling (and often antiquated) water systems. Imagine what smart water solutions can do for South Africa’s struggling water infrastructure.

Millions of tons of grease and oil flowing into our waterways annually

Shocking statistics reveal that approximately 50% of lubricants used on industrial machines and equipment eventually makes their way into the environment where just one litre of used oil has the capacity to poison about a million litres of water.

Significantly, the global market for lubricants is rising and in 2019 increased by 2% to more than 45 million tons showing how dire the consequences are becoming. These figures also indicate just how much needs to be done and changes made in order to reduce the amount of pollutants making their way into our water sources every day.

Solutions are hard to find considering the importance of lubricants in machines ranging from cars to tractors, ships and manufacturing equipment, almost every moving application that bears weight or creates friction needs lubrication to avoid abrasion and heat. Bearings, shafts, spindles and gears are just some of the items that keep the wheels of industry “working like a well-oiled machine” but there is hope with newer and better ways that have already been developed to mitigate the need for grease and oils.

At the forefront of these is world-leading motion plastics manufacturer, igus, who has embarked on a decades long development journey to produce thousands of different formulae of polymers that are tribologically designed with built-in lubrication to operate without oils and grease. As a result, polymers such as its iglidur and others are rapidly replacing steel in applications such as bearings, bushings, gears, robotics and is even used in tandem with steel in applications such as shaft linear guides, energy chains and other friction and abrasion applications.

With no requirement for lubrication these developments have quickly found favour in global clean room

applications, food and beverages, pharmaceuticals and other applications, while its applications in heavy industry, earthmoving, agriculture and some of the toughest environments have enjoyed a slower uptake thanks to its initial scepticism over plastic’s ability to withstand tough tasks. However, the skyrocketing cost of lubrication and the ongoing cost of maintenance in recent years has pushed the agenda and thankfully has steadily filtered through to the point where today the use

of plastic bearings is commonplace in the heaviest machines where they have proven to outlast other materials in a wider range of applications.

“One must remember that In earthmoving alone, a small 16-ton excavator uses about 60 litres of grease per year which is mostly destined to end up in the ground and ultimately in our rivers. Larger machines and industrial plants use proportionately much more and can often be replaced by our igus’ motion plastics solutions,” says igus South Africa managing director, Ian Hewat.

He adds that South Africa is rapidly catching up to global benchmarks and the uptake of its motion plastics solutions is gaining pace across applications in heavy engineering, chemical plants, agriculture and other tough environments, never mind the food and beverages and other “clean environments” who already enjoy the benefits if its lubrication-free products. In fact, several high-profile instances of its products outlasting other materials in bearing and anti-abrasion, noise reduction, as well as corrosion resistance applications, have shown local engineers and designers the value of polymers across all applications.

More recently the company even introduced a free-touse App for smartphones that automatically scrutinises photographs of machines or applications uploaded to the application to identify igus solutions to improve performance with solutions that also negate the use of lubricants. igusGO App is a cutting-edge solution that is free for anyone to download and use. Fortunately, wherever more complex solutions are required, igus’ team of polymer experts are at hand to advise users on applications and are able to call on its German and international laboratories and counterparts to find solutions for customers’ unique requirements.
