Rapid response is vital in dewatering Africa’s mines

Availability of the right equipment – and the expertise to ensure ongoing performance – are proving to be important differentiators in the market for Integrated Pump Technology, as it forges further growth in Africa as a dewatering pump specialist for the mining sector.

Good stock levels are crucial in responding to customer’s urgent dewatering needs, says Jordan Marsh, Managing Director at Integrated Pump Technology – and this was once again confirmed at the latest Electra Mining Africa exhibition.

“With visitors to our exhibition stand coming from all over Africa, it was clear mining customers need a dewatering equipment partner who is responsive and has the right equipment in stock,” says Marsh. “They also need quick turnaround times on the larger diesel-powered pumps, which we can achieve with our Godwin units.”

The mining regions in which Integrated Pump Technology operates have some of the wettest mines in the world, where dewatering is essential for safe and efficient operations. With its range of Grindex submersible pumps and Godwin diesel driven pumps, the company has the depth of experience and local expertise to provide the

optimal dewatering solution.

“In one of our recent customer engagements in Zambia, we supplied suitable 90 kW pumps to a contractor who urgently needed to dewater a section of a mine,” he explains. “Due to our deliberate policy of holding extensive stock in-country, we could quickly get the units on site so that the customer could achieve their goal even quicker than they had planned.”

In addition to timeously receiving a quality solution, the customer also has the comfort of Integrated Pump Technology’s distributor’s high level of experience and knowledge of the product – which is further backed up by the company’s field staff who support its distributor network. Marsh highlights that the company’s localisation policy ensures local distributors are carefully chosen for their knowledge of customer needs, their regulatory compliance and their technical resources.

Holding good stock levels of relevant equipment is one aspect of being able to respond quickly to customers’ emergencies. Another important element is being able to put together pumps systems locally, he says.

“With our well-equipped technical facilities in South Africa, we apply our ‘local build’ approach to speed up the supply of the larger self-priming diesel pumps,” he says. “We know that mines can face lead times of 22 to 30 weeks when they order a fully-assembled pump from abroad. We can do the same job in just two to three weeks, all in accordance with original equipment manufacturer (OEM) specifications.”

The long lead times for overseas builds are often due to the

availability of diesel engines in the country of assembly, he points out. By leveraging its local partnerships with diesel engine OEMs, Integrated Pump Technology can rather source its engines in countries like South Africa. This allows the company to bring in only the wet end of the system, to conduct the assembly locally – and closer to the customer.

“With our strong technical capability, we provide the option of trailer or skid mounted diesel driven pumps,” he says. “The customer may also have a preference for a certain make of diesel engine, to suit their on-site skills set; we engage with a range of OEMs and can source various options for the customer.”

Marsh notes that similar priority is placed on the technical capabilities of its distributors, as Integrated Pump Technology regards their distributors’ in-country workshops as an extension of its own facilities. For this reason, these workshops are inspected and accredited, so servicing and repairs can be conducted to OEM standards. Skills development is also a key part of the process.

“When we appointed our distributor in Zambia, for instance, we brought the technical staff to Johannesburg for specialised training in working on our equipment,” he says. “This includes understanding the detailed procedures for stripping and repairing units, which they can practice hands-on in our facility.”

Integrated Pump Technology’s success in southern and central Africa is now opening doors for further expansion into west African countries, he adds. With the confidence of their OEM partners behind them, the company will soon be making its complete offering of Grindex and Godwin

solutions available to the mining and other sectors in this region.

Revolutionizing water reclamation for pump applications

As the global water crisis intensifies and the cost of clean water escalates, efficient water usage has never been more crucial. Water, despite being one of the most vital resources, is often mismanaged, particularly in industrial applications.

However, a new wave of technological advancements is enabling industries to significantly cut their water consumption, offering the potential for near-zero water costs. By harnessing the power of cutting-edge wastewater recycling systems, businesses can now achieve sustainable water usage, even in applications typically reserved for clean water. This innovative approach integrates three key technologies, allowing industries to recycle wastewater for high-pressure applications. Here’s a breakdown of how this transformative system works in four simple steps:

Step 1: Efficient Water Collection

The process begins with the capture of used or wastewater from any underground or above-ground reservoir. A weir skimmer, connected to a Vesta air-operated double diaphragm solids-handling flap valve pump, transfers the water from the source. This robust pump is engineered to handle high-solid-content water, ensuring reliable operation even in the most demanding conditions. For challenging environments like solids separation in wastewater treatment, agriculture, food processing, and industrial applications, the Vaughan Heavy Duty Chopper Pump plays a pivotal role in pumping and conditioning liquids . Known for its CLOG-FREE GUARANTEE, this pump can shred and chop solids before pumping, preventing blockages and ensuring smooth operation, even when handling debris that would typically hinder standard pumps.

Step 2: Advanced Filtration with Läckeby Rotary Drum Screen

Once the water is collected, it moves to the Läckeby rotary drum screen, an advanced filtration device designed to separate solid particles from the liquid. With the capacity to handle up to 435 L/sec and perforations ranging from 0.6 to 10mm, this filtration step effectively removes all solids. The drum’s internal screw conveys these particles into a separate bin, leaving behind conditioned water that is now ready for further processing.

Step 3: Clean Water Collection

After filtration, the conditioned water is collected in a drum or container, making it immediately available for reuse. This crucial step closes the loop, allowing industries to dramatically reduce their reliance on fresh water by continuously recycling water that would otherwise be discarded.

Step 4: Reclaimed Water Applications with Hydra-Cell Pumps

The final step in the process involves the Hydra-Cell diaphragm pump, which uses the filtered water for both general and high-pressure applications, up to 310 bar and flows up to 595 l/min. This seal-less pump is designed to withstand corrosive and abrasive media, including particulates up to 0.8mm without suffering wear or damage and can even run dry indefinitely. Its durability and versatility make it ideal for a wide range of industries, including Water and Wastewater, Mining, Food & Beverage Processing, Wood, Pulp & Paper, Chemical & Petrochemical, and many more. In applications such as gland seal flush, dust suppression, pumping of hot fluids, chemicals, viscous liquids, salt water, ultrapure fluids and more.

The Future of Water Use

By combining these advanced technologies, industries can now run high-pressure pumps at zero water cost, significantly reducing both water consumption and waste. As businesses strive for more sustainable practices, this compact and eco-friendly system provides a solution to one of the most pressing resource challenges of our time. This breakthrough not only benefits industries financially but also represent a major win for environmental sustainability. By reducing the need for fresh water, companies can lower their ecological footprint without sacrificing operational performance. The future of water use is here, and it’s more sustainable than ever.

PUMPS

Sealing Success

In demanding pump applications, air seals are increasingly offering a reliable solution. This innovative technology ensures reliable performance and reduced maintenance, making it ideal for applications involving abrasive slurries and coarse materials, according to Zach Nepa, Regional Manager at Sealing Equipment Products Co (SEPCO). Pipes, Pumps and Valves Africa finds out more.

“Some applications are significantly more challenging to seal than others,” says Nepa, advocating for the growing adoption of air seals, which are establishing new benchmarks in efficiency and durability—especially in equipment handling slurries and coarse materials.

“When these materials come into contact with traditional mechanical seals, they often lead to excessive wear and can even displace the seals, causing misalignment. Air seals, however, are a specialised form of mechanical seal designed to tolerate misalignment and provide effective sealing where conventional methods fall short. They work well in both dry and wet applications, from powders and bulk solids to hydro-pulpers and slurry pumps.”

Understanding the Mechanics

Nepa explains that the simplicity of air seals is one of their key advantages. “The design is quite straightforward. It’s a pneumatic seal that utilises air or gas to create an effective barrier, sealing the product efficiently.”

“From a side view, you can see how air is channelled into the seal, allowing it to build back pressure while feeding into an internal throttle,” Nepa continues, explaining the mechanics behind air seals. “The seal isn’t in contact with the shaft, which is critical. This back pressure prevents any product from escaping, effectively sealing it in.

“Air is fed into the throttle, which then distributes the air evenly around the shaft. This consistent airflow builds the

back pressure that holds back the material being sealed. Additionally, an anti-rotation pin is incorporated into the design. This allows the seal to pivot with the shaft, which is crucial in many mixing applications where shaft runout is common.”

This ability to move with the shaft is key, especially compared to traditional packing and mechanical seals. “When runout occurs with packing or mechanical seals, the shaft can press against the packing. Since packing has no memory to return to its original form, it leaves an open space that can lead to leaks. Over time, this uneven compression also creates friction points, accelerating wear and creating potential leak paths,” Nepa explains. “The flexible nature of air seals allows them to move with the shaft without causing damage, ensuring a longer-lasting, more reliable seal.”

“Air seals come in a variety of configurations, including solid, rotating, or split designs, with the split air seal being the most commonly used,” Nepa explains.

In simpler applications, solid air seals are mounted after the bearing is removed, and they work well in controlled environments. “But in real-world field conditions, installation isn’t always that straightforward,” he continues. “This is where split air seals come into play.”

The split air seal offers a clamshell design, which allows for much easier and quicker installation. “You can remove each part of the seal one by one, slide them together around the shaft, and pull everything into place. The entire process is incredibly simple and can be completed in under an hour, significantly reducing downtime,” Nepa notes. This ease of installation is a major advantage, especially for industries where equipment availability is critical.

Bespoke Solutions

Air seals are also highly customisable, designed to meet the needs of specific applications. “Take hydropulpers in paper mills, for instance,” Nepa continues. “These vertical applications face enormous pressure from paper stock, which can be highly abrasive and full of contaminants. In these cases, the air seal mounts to the bottom of the stuffing box, providing a bottom-entry solution. We can adapt the seal to prevent contaminants from entering the sealing area, ensuring the longevity and effectiveness of the seal even in such challenging environments.” This adaptability makes air seals a versatile and reliable solution across a wide range of industries where traditional sealing methods struggle to perform. One of the critical features of air seals is their ability to withstand extreme temperatures. While materials are typically adjusted to function within

a 500-degree range, innovative solutions have emerged to accommodate temperatures up to 850 degrees. This capacity allows for their use in high-temperature applications without sacrificing performance.

Best Practices

To ensure the proper installation and function of an air seal, there are several critical steps to follow, says Nepa. “Before beginning, make sure that all machine surfaces are free from contamination, dirt, and burrs. This ensures a smooth installation and prevents any damage or interference with the seal’s performance.” He also advises against overtightening bolts, saying this can lead to misalignment and damage the seal, while it is also crucial to keep the internal components of the system free of any sealant, grease, or lubricants.

According to Nepa, air seals are particularly valuable in the mining industry, where they are employed to seal slurries such as copper concentrates. These seals prevent leakage, thereby safeguarding downstream equipment from the cascading effects of seal failure. “With traditional contact seals, equipment often experiences wear and requires ongoing maintenance. In contrast, air seals offer a ‘set it and forget it’ solution, remaining operational throughout the life of the equipment.”

Nepa points out that even during washdowns and planned stoppages, air seals can continue to function effectively. This capability reduces the need for frequent maintenance and ensures ongoing protection of the equipment. “The design of air seals prioritises reliability and durability, allowing them to withstand the rigours of demanding applications,” he says.

Xylem’s Godwin Rig Pump launches in Africa

The new Godwin Rig Pump tackles the hazards, damage, and costs of mining, tunnelling, and quarry dewatering applications. Dewatering is one of the most hazardous tasks when mining, quarrying, or tunnelling.

Personnel such as drill operators are exposed to risk as they enter drilling and blasting areas to prime or move dewatering pumps, avoid trailing electrical cables in wet and obscured conditions, and navigate other hazards.

Dewatering pumps also need frequent attention. They must move often to avoid damage from rock falls or blast zones, and they incur heavy wear from ingesting large objects and shotcrete residue. All these factors add to frequent maintenance, component replacement, and manual interventions—especially for priming and snoring.

Xylem has developed the Godwin Rig Pump to tackle these specific dewatering challenges. This self-priming pump system solves the toughest dewatering challenges in mining by seamlessly integrating with drilling rigs and using state-of-the-art technology. The pump sits at the back of a drilling rig and can be controlled directly from the rig’s cabin. The suction section and front pipe sit near the drilling face, removing the need for a submersible pump. The electric cables remain with the rig and away from the active drilling area or trailing behind the rig.

The Godwin Rig Pump can operate in intermittent flows, avoiding the high wear caused by snoring. It has the unique ability to run dry indefinitely, thanks to its liquid oil bath mechanical seal, solid silicon carbide rotating and stationary elements, and high-abrasion resistant faces.

This pump is equipped with a hard-iron Flygt NC non-clog impeller, enabling it to handle troublesome shotcrete fibres, and the pipeline uses a pan strainer to manage large objects and other clogging hazards.

It incorporates a non-return valve to protect the pump’s prime and avoid problems such as water hammer pressure surges.

Built to last under the harshest conditions, the Godwin Rig Pump sets the benchmark for mine, quarry, and tunnel dewatering:

● Suction connection: 100mm (4in) flange

● Delivery connection: 80mm (3in) flange

● Max capacity: 160 m³/hr (44l/s) (705 USGPM)

● Max impeller diameter: 214mm

● Max operating temperature: 80ºC (176ºF)

● Max pressure: 7 Bar (101 psi)

● Max suction pressure: 2.8 Bar (40 psi)

● Max casing pressure: 10.5 Bar (152 psi)

● Max operating speed: 3560 rpm

The next generation of dewatering pumps, now in Africa Xylem’s Godwin Rig Pump has proven its strength in several major mining markets and is now available to African operators.

Mines, quarries, and anyone with extreme dewatering requirements can integrate these new, easy-to-move compact pump systems that improve performance and reduce site risks.

“Underground and quarry dewatering is very hazardous work, and it’s also very hard on dewatering pumps. Our designers and engineers looked closely at the specific issues that hamper traditional pumps, and worked with our extensive field experience to develop a next-generation dewatering pump that addresses those issues.

The Godwin Rig Pump is not simply a new dewatering solution. It’s superior in every way to previous options, improving safety, performance, efficiency, and lifetime value,” says Chetan Mistry, Strategy and Marketing Manager at Xylem Africa.

The Godwin Rig Pump provides faster and longer drilling without downtime while lowering costs, with anti-clogging features, dry-run protection, and a non-return valve to significantly reduce pump wear and damage. Compact and designed for rig operations, it reduces hazard risks from accessing the drill area or managing electrical trailing cables.

Fit for the digital age

Digital automation helps production run smoothly, precisely, reliably, and protects against unexpected system downtime. This also means that it significantly enhances the competitiveness of the user and helps conserve resources. Data is becoming the new currency of economy and ecology, especially in challenging times like these.

Sensors and measurement technologies collect data from valves and actuators, which is then evaluated to answer the question of whether an automated process is running efficiently.

For example, actuators automatically collect and store process data such as valve position, valve operations, ambient temperature and vibration. The digitally

recorded data allows the plant operator to identify where maintenance is required. Corrective measures can be initiated in good time, avoiding unexpected breakdowns.

Big things in store for the industry

However, digitally driven automation doesn’t only lead to optimised processes, reduced material usage and energy savings; it is also a promising strategy to combat the increasing shortage of skilled labour. From this point of view, the valve industry is providing valuable services, as it makes plant operators fit for the digital age.

But digitalisation is by no means the final chapter in the development of automation. In the future, artificial intelligence will have an increasing impact on processes. It will control systems, without human decision. Machines reacting to machines. There are exciting times ahead for plant operators and the valve industry!

Revolutionizing wastewater management in four cities through water mixing

Wastewater lift stations serve as the backbone of municipal sewage systems, quietly ensuring the seamless movement of wastewater from lower to higher elevations where gravity alone proves insufficient.

Despite their crucial role, these stations grapple with a persistent nemesis: grease buildup. This accumulation poses a significant threat, causing operational disruptions and environmental risks when left unattended.

Historically, lift station operators have turned to chemical treatments as the primary means of managing grease buildup. However, while effective to some extent, these methods carry inherent drawbacks. Environmental concerns, regulatory compliance issues, and the ongoing operational expenses associated with chemical treatments have spurred the quest for more sustainable alternatives.

However, a new technology offers hope for water managers in search of options. The HydraForce Lift Station Agitator, produced by Kasco, offers a transformative approach to grease management, harnessing the power of movement and agitation to combat buildup effectively. By eschewing chemical interventions, HydraForce mitigates environmental impact while alleviating regulatory burdens and reducing long-term operational costs.

Over the past year, HydraForce has been tested in four U.S. communities – and the results have been promising.

Farmers branch: a greasy situation transformed

In Farmers Branch, Texas, Director of Public Works James Ryan Sartor faced mounting grease issues amid rapid urban development. A sustainable remedy was needed.

“We had to upgrade to handle the increased flows,” said Sartor, “and as these new additions to the city were being occupied, we noticed the lift station was developing

a grease issue.” Sartor had recently learned about HydraForce from Axis Construction, a partner organization. Recognizing the need for change, Sartor decided to try the mixing system as an experimental solution.

“After examining its design and construction,” he said, “I talked with Axis about installing the device in a lift station wet well for grease remediation.”

The implementation of the HydraForce Lift Station Agitator yielded transformative outcomes. “By early May, we started to experience amazing results,” Sartor recalled. “The station was staying very clean, the water was clearer, and there was far less odor.” The agitator’s ability to mix and agitate the F.O.G. – fat, oil and grease –proved instrumental in preventing accumulation, ensuring uninterrupted lift station performance.

Moreover, Sartor highlighted the significant cost savings and operational efficiencies achieved by using HydraForce. “Our chemical treatments had been costing us thousands of dollars a year,” he remarked. “We now perform our standard weekly inspections of this site and have yet to experience a need for grease removal since installation.”

Rockwall: From “matting” to maintenance ease

Rockwall, Texas, also confronted enduring issues with grease buildup in its lift stations.

Shon Bellah, Production Technical Supervisor for the city, described the problem of “matting” – fat that congeals in a layer on the surface of wastewater in tanks. The fatty “mats,” which can be several feet thick, pose a severe

clogging risk for water treatment facilities. And they are extremely difficult to remove.

Bellah also opted to try HydraForce as a preventive force against grease development. He noticed an impact immediately.

“Before HydraForce,” he said, “we would treat our sewage with chemicals like Alkegen, and even then we had to vac the matting out every Friday. Not only did we have to pay for the chemicals, there were a lot of additional related time and human costs. It would take four or five people probably two to three hours of work to bring in the utility truck, vac the stuff out, dump it and wash it. But when we got the aeration device in, it helped out a lot.”

Bellah noted agitating the water to eliminate greasing reduced manual labor and enhanced operational efficiency. In fact, the implementation of HydraForce revolutionized Rockwall’s lift station maintenance practices. Bellah highlighted a significant reduction in the need for the weekly cleanings that had previously consumed those valuable resources. He explained, “We installed the HydraForce in September of 2022, and since then, we haven’t needed to vac the system at all. In fact, the first time was vacced it was just this past month – February of 2024. It’s been good, to say the least.”

HydraForce not only alleviated the burden of manual labor but also freed personnel to focus on other essential tasks, streamlining operations and optimizing resource allocation within Rockwall’s wastewater management framework.

“Everything’s running smooth like it’s supposed to. It just takes one big thing off your plate so you can focus more on your daily routine,” Bellah said. “And it frees up the truck in case there is an actual external problem or emergency.”

Keller: Peace of mind and environmental stewardship

Randy Worthen is the Water Operations Supervisor in Keller, Texas, a city of 46,000 that has no fewer than six lift stations – a high number for its size. Worthen had been using chemicals and bacterial treatments to combat greasing. Like his counterpart in Rockwall, Worthen found the frequent need to manually break up matting and remove it from his stations a drain on resources.

Worthen also hailed HydraForce as a game-changer in his city’s wastewater management approach. “I would say with no exaggeration, it’s a 99 percent improvement,” he said. “It’s a major, major improvement.”

HydraForce’s implementation ushered in a new era of efficiency and sustainability for Keller’s wastewater infrastructure. As it had in Rockwall, Worthen noted HydraForce had virtually eliminated the need for chemical treatments and manual cleanings, marking a significant departure from traditional maintenance practices. “We use no chemicals anymore,” he said. “None whatsoever.”

Beyond operational enhancements, Worthen said, HydraForce’s impact extended to environmental stewardship, mitigating the risks associated with lift station failures and overflows. He underscored HydraForce’s pivotal role in safeguarding Keller’s ecosystem and public health. After all, in Keller, more lift stations meant more opportunities for danger to the community or the

environment should any facility experience clogging that shut down operations.

“For me,” Worthen said, “it’s about more than just making our workload easier. It’s about peace of mind.”

Prescott: Dramatic reduction in cleaning frequency

In Prescott, Wisconsin, Matt Holman, a wastewater and water operator in the city’s Public Works/Utilities Department, emphasized the critical role of HydraForce in addressing the buildup of F.O.G., particularly in lift stations serving high-density restaurant areas.

Holman stressed the significance of HydraForce’s impact, stating, “Prescott’s been using the HydraForce diffusers in our main lift station for a couple of months now, and we have seen a drastic change in our use of cleaning services.”

HydraForce’s implementation in Prescott marked a transformative milestone in their wastewater management strategy. Holman underscored the tangible benefits of HydraForce, highlighting its instrumental role in reducing cleaning services and saving valuable time and resources. He noted, “You just pump the lift station down and it probably takes about ten minutes, versus 45 minutes to an hour before.”

The adoption of water agitation treatment not only streamlined operational processes but also ensured uninterrupted wastewater flow, mitigating the risk of potential disruptions.

The new tool is now playing a vital role in Prescott’s wastewater infrastructure, offering an effective solution to combat F.O.G. buildup and uphold operational efficiency in lift stations serving vital community sectors.

These narratives from Farmers Branch, Rockwall, Keller, and Prescott serve as compelling testimonials to the promise an innovative technology like HydraForce has for reshaping conventional wastewater management practices and philosophies.

Through its innovative mixing technology, HydraForce not only mitigates grease buildup but also redefines operational efficiency in lift stations, embodying a sustainable approach to wastewater treatment.

As James Ryan Sartor of Farmers Branch noted, “The HydraForce Lift Station Agitator not only eliminated the need for chemical treatments, it also resulted in significant cost savings and operational efficiencies.”

In an era defined by increasing environmental consciousness and the imperative for sustainable practices, the emergence of such technologies marks a pivotal moment in wastewater management.

As municipalities strive to navigate the complexities of modern infrastructure challenges, tools like HydraForce hold the promise of cleaner, more efficient wastewater systems, now and in the future.

How does a hydraulic system work?

A hydraulic system is a closed system that converts pressurized fluid to mechanical energy. Hydraulic fluid is moved by pumps through control valves and on to mechanical actuators like hydraulic cylinders or motors, which then use the pressure to move implements such as tractor buckets, excavators, and lift cranes.

Components of a Hydraulic System

A hydraulic system comprises various components to keep the fluid under the desired pressure, clean, and moving in the right direction. Below is an overview of those components

Reservoir Tank

The hydraulic tank acts as a reservoir, holding fluid, and is connected directly to the pump. It allows air bubbles to dissipate and contamination particles to settle and the oil to cool while it is not circulating. A vented filter cap controls airflow, and a filter or strainer keeps contaminants from the hydraulic fluid.

Pump and Engine

The hydraulic pump moves liquid from the reservoir tank through the system driven by an engine. Pump designs are typically two-stage, PTO or manual hydraulic, while the engine can be gas, diesel or electric depending on access to power, the horsepower needed and mounting style.

Pressure Gauges and Relief Valve

Once liquid is circulating, gauges can be used virtually anywhere in the system to monitor pressure. In addition, a relief valve controls the fluid pressure that powers the hydraulic cylinder; excess fluid is returned to the reservoir tank. This prevents pressure build-up and potential damage to equipment.

Valve Assembly

The hydraulic valve assembly controls the direction, pressure and flow rate of fluid through a hydraulic circuit. It regulates the speed of motors and movement of cylinders. Directional control valves are most common, controlling fluid flow from the pump to the cylinders and other system components.

Cylinder

A hydraulic cylinder is an actuator that creates linear movement by converting hydraulic energy back to a mechanical movement – so it is the component that drives the work performed by mobile equipment. Cylinders can be used to lift, push, pull and press loads that require exceptional force.

Motor

Similar to cylinders, motors are actuators that converts hydraulic pressure and flow into movement, but it’s converted into torque and angular displacement (rotation) rather than linear motion.

The amount of pressure and displacement of a motor will determine how much torque is produced while the amount of flow will determine the speed.

Flow Control Valve

The purpose of a flow control valve is to regulate the flow rate to motors and cylinders, thereby regulating the speed of those components.

Fluid Cooler

This unit removes the excess heat generated from the hydraulic fluid and helps to keep the temperature within a limited range before returning to the reservoir.

Without proper cooling, the hydraulic system could overheat, causing component damage. Keeping the system properly cooled also extends hydraulic fluid life.

Lower TCO from OEM maintenance

Achieving the best return on their plant investment is a primary goal for mines, and partnering with OEMs like Weir is a strategic way to enhance equipment performance while reducing the total cost of ownership.

The company is at the forefront of helping mines transition from reactive to prescriptive maintenance approaches, ensuring sustainable and safe operations through the optimisation of technology and equipment.

“We have an extensive footprint of equipment around Africa, and focus on adding further value to these assets through the correct maintenance strategy,” says Grant Potgieter, Strategic Services Manager at Weir. “This means a constant monitoring process, where we can track performance while looking for opportunities to raise our customers’ plant availability for greater productivity.”

Plant monitoring will invariably include a regular wear analysis of components, to monitor whether such wear is in line with expectations, explains Potgieter, as well as to predict future wear and component life. Analysing this wear, however, involves a considerable amount of data from the plant operation itself, such as ore characteristics and throughput. “Here is it important to remember that each site will have its own variables, so it is not possible to apply a standard template without understanding the specific plant,” he says. “Operating conditions may also change over time, so the assessment requires close collaboration between our team and the plant personnel on the mine.” This allows a foundation of data to be established, on which to base the relevant corrective

action, whether this is through technology, training or other interventions. Such action may be initially prompted by data that Weir picks up in its procurement process.

“Our years of experience in this market, and our careful documentation of component wear life, including historical and process information, allows us to estimate how long a certain component will last under predefined conditions,” he says. “By generating strategic reports from our procurement system, we can see if a customer is ordering components more frequently than they should be – suggesting that there is wear taking place.”

Technicians from Weir can then visit the site and examine the conditions more closely as part of a root cause analysis. This is most effectively done with a multidisciplinary team including process engineers and mechanical experts, to identify first-hand what the challenge is, and how best to address it.

Potgieter highlights the role of accurate measurement of equipment performance and condition, pointing to the fact that this is not always constant when conducted manually. To provide a platform that would overcome human error, Weir offers its own digital platform to harvest data continuously, accurately and objectively.

“It is significant that we developed our own system to do

this, as we understand our equipment solutions better than anyone,” he explains. “Our digital platform allows us not only to gather and process the data from our equipment, but also generates recommendations which identify the actual cause of anomalies.”

As an example, if a sensor transmits a certain vibration signature from an item of equipment, a trained Weir Minerals condition monitoring expert will be able to verify system notifications.

While technology could be one part of the solution, he says, good communication is also crucial. To avoid any lack of communication through people working in silos, Weir arranges monthly quality meetings with customers – to ensure that all stakeholders are on board.

“This has proved to be a valuable way of getting all players involved and committed to the solutions that are agreed,” he says. “In this round table environment, everybody can be allocated a clear role, with tasks and responsibilities agreed in a transparent and accountable manner.”

This format also brings in all the necessary disciplines –from electrical and instrumentation through to mechanical and process – to reflect on the proposed solutions and ensure that the one selected is optimal.

“The key performance indicator that is shared by everyone in these meetings is cost optimisation, so this is really our focus with our discussion and solution,” he says. “We look

holistically at safety, value and technology to ensure that whatever is spent on an intervention helps to lower the total cost of ownership.”

This often involves considerable change management, says Potgieter, as long term maintenance strategies may require mine personnel to adjust their procedures. Recognised for its expertise in its aftermarket services, Weir is frequently engaged by its customers to work on strategic shifts in their operating practices to optimise aspects such as equipment turnaround time and costs of refurbishment.

“We collaborate with customers as they adjust their own maintenance strategies,” he says. “To optimise the maintenance of rotables, for instance, we are able to provide service exchange units at regular intervals, as the customer removes a unit from service after a predetermined time.”

This avoids the higher cost of running a unit to failure before repairing, and reduces the risk of any unscheduled maintenance for breakdowns. As the OEM, Weir is then also able to refurbish equipment to their original standard, and offer the appropriate warranty.

Innovative financing models drive successful solar transitions for businesses

South Africa’s ongoing energy crisis, characterised by soaring electricity prices and persistent load-shedding, has driven local businesses to explore sustainable and reliable alternatives.

By partnering with the right solar developers, companies can transition seamlessly to solar energy in a financially viable way.

A notable example is the recent completion of BT Industrial Group’s new 1MW solar plant system in Benoni. This project demonstrates how innovative, tailored financing can eliminate the common barriers to solar adoption, ensuring reliable power, reduced electricity costs, and maximised tax benefits.

Energy crisis impact and response

The energy crisis led to operational and financial disruptions at BT Industrial, reducing their productivity by 25%. “To protect our long-term viability, we needed to address the energy uncertainty and the increasing cost of Eskom electricity, which has risen by a compound annual growth rate of 19% over the last four years. This surge almost doubled BT Industrial’s electricity bill from R600,000 to R1,000,000, and with the slated future increases, it’s projected to reach R1.2 - R1.3 million. This is a significant cost increase, squeezing our profit margins, especially in export markets where we cannot pass on these costs to our customers.” says Kgomotso Lekola, Founder and Group Managing Director of BT Industrial Group.

To overcome this, BT Industrial needed a solution that secured energy supply certainty, delivered cost savings, and maximised tax benefits—all without putting undue pressure on its finances.

Finding an optimal financing model

An essential criterion for BT Industrial while choosing the right solar developer was owning the solar asset on their balance sheet without any upfront costs while accessing solar tax benefits. Traditional PPA (Power Purchase Agreement) financing, an off-balance sheet model, did not meet these needs. They also wanted to mitigate performance management risks once the solar plant was operational.

After evaluating several options, they selected a solar financing model from Candi Solar, a leading solar power developer, financier, and operator for the commercial and industrial sectors.

On-balance sheet financing model with no upfront cost Lekola explains, “We chose Candi Solar’s innovative model, which provided the best value without increasing our financial risk. Candi Solar offered a tailored solution that met all our criteria, including long-term energy cost certainty and full performance management.”

Candi Solar’s innovative PLIS (Performance Linked

Instalment Sale) option, an on-balance sheet solar finance model, offered BT Industrial all the financial advantages of a PPA while directly benefiting from the solar tax incentive, making the transition to solar more cost-effective. “The tailored payment structures allowed us to avoid a large capital outlay, ensuring no added financial burden,” adds Richard Flamand, Co-Country Lead for Candi Solar South Africa.

The solar plant, constructed by Nuvo Energy with Changa Energy as project developer, consists of 1,604 solar panels and seven grid-tied inverters, ensuring independence from Eskom. With Eskom proposing further tariff hikes, BT Industrial’s investment in solar will yield significant utility cost reductions. The plant has received approval to export excess electricity back to the grid, which will lead to even greater savings in the future.

Zero-risk, end-to-end solar solutions

BT Industrial also prioritised a low-risk, comprehensive solar solution. “Candi Solar provides full operational and performance management of the solar system, allowing our team to focus on core business activities,” says Lekola. Candi Solar’s end-to-end solution includes everything from construction to asset maintenance, ensuring ongoing performance and reliability.

“We specialise in highly customised, financially attractive and risk-free solar power solutions that are managed end-to-end, meeting all the criteria companies may require – from business continuity to cost savings and tax optimisation, and from no upfront costs to zero risk,” concludes Flamand. “With 145 successful installations across South Africa and India, we are confident we can provide the right solution to empower our commercial and industrial clients to transition to solar energy with confidence and peace of mind.”

Let’s talk about acid mine drainage

A recent report, Remediation potential of mining, agro-industrial, and urban wastes against acid mine drainage highlights the impact of sulfide minerals, a geological byproduct of mining, on the environment; stating that when mixed with oxidising and rainfall conditions it leads to generation of acid mine drainage (AMD), which is commonly associated with serious environmental problems worldwide.

“Acid mine drainage is problematic because of its scale, both in space and time, as it can affect both mining areas and their surroundings over large kilometres for decades or centuries,” notes the report.

The mining sector inadvertently contributes to AMD. The processes involved in mining, such as drilling, blasting, and the use of chemicals for mineral extraction, expose sulfide minerals to the environment. Once exposed, these minerals undergo oxidation reactions, producing sulfuric acid. This acid leaches into the groundwater, contaminating it with dissolved metals like iron, aluminium, and manganese.

The impact of AMD is far reaching. Apart from environmental degradation, it also poses a significant risk to human health – heavy metals such as arsenic and lead, often present in AMD, are toxic and can lead to severe health issues. The cleanup of ADM is also extremely costly.

Like other water and wastewater (WWW) operations, AMD requires effective management to mitigate its impact. For one, contaminated water needs to be treated to neutralise acidity and remove harmful contaminants before releasing it back into the environment.

Complex water treatment plant therefore plays a critical role in managing AMD. These plants are designed to treat contaminated water from mining operations, removing impurities and adjusting the pH to safe levels.

For example, in South Africa, the eMalahleni Water Reclamation Plant - commissioned in 2010 - produces drinking water, with its feedwater coming from four coal mines in the area.

Operational efficiency

From a technological point of view, AMD plants must be managed by advanced management systems that allow for automation, monitoring and control – all vital cogs in

ensuring plants run optimally:

• Industrial automation and control Systems - PLCs (Programmable Logic Controllers), offer precise control and automation of treatment processes. These systems ensure timely and accurate adjustments in response to varying water quality conditions.

• Advanced instrumentation for monitoring water quality, flow rates, and chemical composition is vital. There are several advanced instrumentation solutions available that enable real-time monitoring and control, ensuring the effective treatment of contaminated water.

• IoT-enabled platforms integrate connected products, edge control, and applications, analytics, and services. It facilitates remote monitoring and management of treatment plants, enhancing operational efficiency and ensuring compliance with environmental regulations.

• Reverse osmosis systems – ideal for those or areas require high-quality water purification, reverse osmosis systems are employed to remove dissolved salts and contaminants, producing water that meets stringent drinking standards.

Treated water can also be a valuable commodity; mining companies have the opportunity to purify AMD to potable standards and sell it to municipalities, therefore contributing to local water supplies and generating additional revenue.

AMD is global challenge which is why it requires a concerted effort from all parties concerned. Companies such as Schneider Electric can undoubtedly improve AMD management, providing comprehensive automation and control systems to optimise operations.
