Pump specification is critical to successful mine dewatering (Image source: Integrated Pump Technology)

As mining operations across Africa continue to face increasingly complex water management challenges, the correct specification of dewatering pumps has become one of the most important factors influencing operational efficiency, safety and production continuity

While pumps are often viewed as standalone pieces of equipment, successful dewatering requires a detailed understanding of site conditions, water characteristics, duty requirements and long-term operational objectives.

Incorrectly specified equipment can lead to excessive energy consumption, reduced pump life, frequent breakdowns, production interruptions and significantly higher operating costs.

According to Jordan Marsh, managing director of Integrated Pump Technology, many dewatering challenges experienced by mining operations can be traced back to pumps being selected based solely on flow rate requirements without sufficient consideration of the broader application.

“Effective dewatering is about much more than moving water from one point to another," said Marsh.

“Every application has unique characteristics and unless these are properly assessed, the selected pump may not deliver the required performance or reliability."

He said that factors such as pumping distance, total dynamic head, solids content, water chemistry, seasonal fluctuations, power availability and installation conditions all need to be evaluated during the specification process.

“Two applications may require the same flow rate, but the actual pump solution could be completely different depending on the site conditions. This is why a detailed assessment is critical before any equipment is selected.”

Marsh said that as mining operations move deeper underground and surface mines become larger, dewatering systems are often required to operate over longer distances and against higher heads.

These conditions place additional demands on pumping equipment and require careful consideration of pump design, motor sizing and overall system configuration.

The increasing focus on sustainability is also influencing pump selection decisions.

Mines are under pressure to reduce energy consumption while maintaining production targets, making efficiency an important consideration during the specification phase.

“A correctly specified pump will not only deliver reliable performance but can also significantly reduce energy costs and maintenance requirements over its operational life,” said Marsh.

Integrated Pump Technology works closely with mining customers to evaluate individual site requirements before recommending suitable dewatering solutions.

The company supplies a range of Grindex electric submersible pumps and Godwin diesel-driven pumps designed for demanding mining applications across Africa.

Its dewatering portfolio includes Grindex electric submersible pumps ranging from approximately 1 kW to more than 90 kW, covering drainage, sludge and slurry applications.

Its Godwin diesel-driven pump range incorporates both automatic self-priming and high-head pump technologies with capacities capable of delivering flow rates from a few litres per second to several thousand cubic metres per hour, depending on the application.

This breadth of offering allows the company to match equipment precisely to site conditions, pumping distances, head requirements and water characteristics.

Marsh added that the most successful dewatering projects are those where the pump supplier is involved early in the planning process.

“When pump selection is approached as part of the overall mine water management strategy rather than simply an equipment purchase, operations generally achieve better reliability, lower lifecycle costs and more effective water control,” he noted.

As mining operations continue to contend with groundwater ingress, seasonal rainfall and increasingly demanding production environments, ensuring that pumps are correctly specified from the outset remains a key factor in achieving safe, reliable and cost effective dewatering performance.

Its presence at Electra Mining Africa 2026 confirmed to SEW-EURODRIVE that customers are seeking not only the highest levels of innovation and workmanship, but also comprehensive support throughout the full lifecycle of their drive solutions

This commitment to lifecycle support has been central to SEW-EURODRIVE's evolution in Africa in recent years, including its ambitious Phase 2 development at its headquarters in Aeroton, according to Jonathan McKey, National Sales and Marketing Manager at SEW-EURODRIVE.

"Our objective has been to further strengthen our trusted partnerships by localising more capabilities and supporting customers across the full lifecycle of their equipment," McKey explained.

"Customers know us as a reliable original equipment manufacturer (OEM) and we have now strengthened that relationship through additional engineering services, faster turnaround times, greater quality control and a genuine single-source solution for drivetrain support."

This broader engineering philosophy was demonstrated at Electra Mining Africa, where visitors experienced the company's integrated approach to drivetrain support. SEW-EURODRIVE showcased technologies spanning intelligent drive systems, condition monitoring and digital diagnostics. Its DriveRadar predictive maintenance system attracted particular interest, alongside its energy optimisation tools and medium-voltage motor solutions.

"Rather than presenting these as standalone products, the exhibition allowed us to demonstrate how they integrate into a complete lifecycle support strategy for mining and industrial operations," he said.

"We were able to share our depth of engineering expertise with visitors and demonstrate the extent of our local investment, which enables us to provide the comprehensive lifecycle support they are looking for."

A significant element of SEW-EURODRIVE's strategy is its continued investment in local infrastructure. By bringing more engineering capabilities in-house, the company has reduced its dependence on multiple subcontractors, improving quality assurance while shortening repair lead times. Capabilities within the recently completed Phase 2 development include motor rewinding, steel fabrication, shaft manufacturing, stress relieving, sandblasting and complete load testing.

"This approach gives us tighter control over repair standards and pricing," remarked McKey. "It also gives customers confidence that critical drivetrain assets are restored to OEM specifications."

Complementing these capabilities are the company's Experience Centres, where customers can evaluate proposed solutions through simulations. Willem Strydom, Business Development Electronics Manager at SEW-EURODRIVE, explains that many customers want to pursue productivity improvements and greater energy efficiency, but cannot simply stop production to test new technologies.

"We have therefore invested in Experience Centres where we can replicate real applications," Strydom says. "Here, we can compare existing equipment with proposed solutions and allow customers to see the results before making an investment decision."

Applications such as conveyors and automation systems can be replicated, enabling customers to test SEW-EURODRIVE's software, hardware and energy optimisation strategies before implementation.

"This significantly reduces implementation risk for operations that cannot afford unplanned downtime," he stated. "Visitors to our exhibition stands at Electra Mining Africa responded very positively to this practical demonstration capability."

McKey emphasises that these investments have been made with a clear focus on improving both equipment performance and customer sustainability.

"Customers come to us for solutions, so we focus on engineering the complete package," he commented. "This starts with selecting the correct equipment and extends to supporting the installation, programming and lifecycle management that ensures it delivers the expected performance."

Importantly, these services are offered not only for SEW-EURODRIVE equipment but also for drive-related assets from other OEMs. The company's expanded engineering capability enables it to develop technical solutions for a wide range of brands and components.

He also highlights the value of SEW-EURODRIVE's consultative engineering approach.

"This means we begin engaging well before a purchase decision is made," McKey said. "Our engineering teams review a customer's initial specification and analyse the application to determine whether a more efficient solution is available."

Using detailed energy assessments and application studies, engineers can frequently identify opportunities to optimise drive sizing, reduce installed power and lower operating costs without compromising production performance.

"These engineering interventions improve both energy efficiency and total cost of ownership, while helping customers meet increasingly demanding sustainability targets," he explains.

Strydom notes that digitalisation is becoming an increasingly important component of SEW-EURODRIVE's strategy. Intelligent condition monitoring enables maintenance teams to identify developing problems long before they become critical failures, allowing planned intervention rather than costly emergency repairs.

"Our DriveRadar demonstrations at Electra Mining Africa showed visitors how remote asset monitoring enables plant managers to oversee equipment performance across multiple operations from laptops, tablets or mobile devices," he stated. "By providing real-time asset condition data, maintenance teams can prioritise interventions based on actual equipment health rather than fixed maintenance schedules, improving equipment availability while reducing unnecessary maintenance expenditure."

McKey believes that a fundamental shift in maintenance philosophy is underway, with technology playing a central role in eliminating unwanted surprises from plant operations while helping customers work smarter.

"We believe that digital technologies enhance skills rather than replace people," he commented.

Training therefore remains a cornerstone of SEW-EURODRIVE's partnership model. Its expanded DriveAcademy provides training for artisans, technicians, engineers, foremen, reliability specialists and management teams, with programmes tailored to specific operational requirements. The curriculum extends beyond mechanical equipment to include electronics, automation, programming, condition monitoring and modern drive technologies.

The rental market offers a solution to costly machinery purchases (Image source: SkyJacks)

With rental solutions available, you do not necessarily need to own expensive equipment anymore — that is the core message from SkyJacks, as it highlights the shift from ‘ownership’ to ‘access’ with expanded equipment solutions at Electra Mining 2026

As mining, construction and industrial businesses continue to navigate changing project demands, rising operational costs and the need for greater flexibility, the traditional approach of owning every piece of equipment is evolving, the company believes.

At Electra Mining 2026, SkyJacks will showcase how businesses can gain access to world-class equipment through flexible rental solutions, enabling them to adapt quickly while reducing the financial pressure associated with asset ownership.

“Businesses today need flexibility as much as they need reliable equipment,” said Darryn Jacobs, managing director at SkyJacks.

“While purchasing remains the right option for many organisations, rental provides an alternative approach that allows companies to access the equipment they need without being locked into assets that may no longer align with changing operational requirements.”

A leading provider of powered access, material handling and lifting equipment across South Africa and the broader SADC region, SkyJacks will showcase its expanded portfolio at the Johannesburg Expo Centre, Nasrec.

Alongside its established range of globally recognised OEM brands, including Dingli, Faresin, Jekko, GEDA and ALR, the company will introduce two new additions to its offering: Hyundai Forklifts and MACH industrial cleaning solutions.

The expanded portfolio reinforces its position as a comprehensive equipment partner, providing solutions that support safety, productivity and efficiency across mining, construction, industrial maintenance and logistics environments.

According to Jacobs, rental provides businesses with the ability to adapt as project scopes change.

“A company may start a project requiring a 20-metre access machine but later discover that it needs equipment capable of reaching 40 metres. With rental, they can return the existing machine and transition to a solution that better meets their requirements,” he said.

“When equipment is purchased outright, businesses can find themselves committed to an asset that may no longer provide the right capability, creating unnecessary costs and limiting flexibility.”

Beyond providing access to specialised equipment, rental solutions also help customers manage the ongoing costs associated with ownership.Maintenance, servicing and equipment support are included as part of the rental offering, allowing businesses to focus on operations rather than managing additional asset-related expenses.

“Customers are looking for predictable costs and reliable uptime,” said Jacobs.“With rental, they have access to professionally maintained equipment without the additional burden of maintenance, repairs and replacement costs. This allows them to focus on productivity while knowing their equipment is supported throughout its lifecycle.”

Technology group Wärtsilä will provide five Wärtsilä 32 engines for a 14 MW captive power plant being developed for the Diamba Sud Gold Project in Senegal

The dedicated power plant will provide the reliable electricity supply required for the mine’s operations. Located in a remote area, the Diamba Sud project will rely entirely on the captive facility for its power requirements.

The order was placed by Africa Power Services (APS), the France-based engineering, procurement and construction (EPC) contractor responsible for the power plant, on behalf of Fortuna Mining. Wärtsilä recorded the order as order intake during the second quarter of 2026.

Wärtsilä 32 engines to power remote Senegal mine

The Wärtsilä 32 generating set has been in successful operation for 30 years and has supplied more than 8,000 MW of energy to customers globally. Its fast-starting capability also allows engine-based power systems to incorporate variable renewable sources, including solar and wind, by providing flexibility for balancing power supply and demand.

Fortuna Mining has plans to introduce renewable energy into the mine’s microgrid in the future, with the Wärtsilä engines providing the flexibility required to complement intermittent renewable generation.

“Operating a remote, off-grid mine requires reliable power, as any unscheduled downtime carries financial and operational risks. Wärtsilä’s engines deliver the continuous performance required for such demanding conditions. Selecting them for Diamba Sud ensures we mitigate operational risks from day one, while building a power foundation that can seamlessly integrate renewable energy assets as the mine evolves,” says Cedric Fernandez, Managing Director at APS.

Wärtsilä’s contract extends beyond the supply of the engine generating sets. Its scope includes basic engineering, engine-specific auxiliary equipment and the engine control and monitoring system. The company will also provide advisory services during installation and commissioning.

The use of multiple engine-generating sets is intended to provide the power plant with greater flexibility to respond to changing mine loads while maintaining efficient operation. The configuration will also provide the operational flexibility needed to accommodate renewable generation as the microgrid develops.

“This repeat order from APS reinforces Wärtsilä’s position as a trusted and reliable solution provider for the mining industry’s power needs,” commented Marc Thiriet, energy business director, Africa at Wärtsilä Energy.

“Mining operations are under dual pressure to maintain maximum uptime while actively charting a path toward decarbonisation. By deploying multiple smaller engine-generating sets instead of a single large unit, we enable the plant to match fluctuating load demands with high precision, maximizing fuel efficiency and reducing emissions. Critically, these engines feature the starting flexibility required to balance the intermittent nature of solar or wind power, thereby complimenting Fortuna Mining’s future plans to introduce renewables to this microgrid strengthening the mines operational stability.”

Diamba Sud power plant targets 2027 operation

Delivery of the Wärtsilä equipment is scheduled for March 2027, while the captive power plant is expected to begin operations by the end of 2027.

The project is being developed for Fortuna Mining, a Canadian mining company advancing the Diamba Sud Gold Project in Senegal. Fortuna acquired the project in September 2023.

Diamba Sud is situated within the Kenieba–Koudougou Inlier, a geologically important region extending across eastern Senegal and western Mali. The area hosts several major gold deposits.

The dedicated 14 MW power plant will form a critical part of the mine’s infrastructure, providing the electricity required for operations at the remote site while establishing a foundation for the future integration of renewable energy into the project’s microgrid.
