Grindex pumps prove tough in copperbelt mines

Integrated Pump Technology is recording increased demand for its Grindex submersible dewatering pumps across Zambia’s Copperbelt, where the equipment is delivering reliable performance in some of the region’s most challenging mining environments

Designed for harsh underground environments, the pumps combine rugged construction, operational flexibility and strong local technical support to deliver consistent performance.

According to Alfred Kelsey, sales manager at Integrated Pump Technology, Grindex pumps have demonstrated notable success in specialist applications such as the cleaning of underground dams. One recent project, carried out through the company’s Kitwe based distributor IES, involved the deployment of a 14 kW Grindex Bravo 400 to address severe sludge build up that had compromised dam capacity.

“Our customer faced a serious challenge, with sediment accumulation drastically reducing the capacity of their underground dams,” Kelsey explained.

“Conventional dewatering pumps aren’t designed for handling this slurry density, but the submersible Grindex Bravo 400 proved ideal.”

Built with hard iron components for high abrasion resistance and fitted with an integrated agitator, the Bravo 400 is able to re suspend settled material, enabling efficient removal of dense sludge. The pump is also rated to IP68, allowing safe operation at depths of up to 20 metres.

Kelsey notes that interest in Grindex dewatering pumps is increasing rapidly across the Copperbelt as mines look for reliable long term solutions.

“The reliability and quality of Grindex pumps are major drawcards, complemented by the integrated smart systems on the 2.2 kW to 18 kW models, offering genuine plug-and-play functionality,” Kelsey noted.

“This feature allows for fully automatic operation with comprehensive built-in protections.”

For larger duty requirements, Integrated Pump Technology supplies Grindex pumps in the 25 kW to 90 kW range, supported by external control and monitoring panels. The product range can also be tailored to suit different abrasive conditions through material options.

“Customers can specify nitrile rubber or polyurethane linings to handle highly abrasive environments,” he added. “A popular choice is internal polyurethane inserts paired with a lightweight, corrosion-resistant stainless steel casing.”

The stainless steel design significantly reduces pump weight, an important advantage in underground settings where equipment is frequently moved by hand. A split handle configuration further improves ease of transport, allowing two people to carry the unit safely.

“Our rapid response capability sets us apart in the Copperbelt region,” Kelsey emphasised. “Through our close partnership with IES, we ensure technicians remain highly skilled, aligned with OEM standards and equipped with a first-class workshop.”

This local support model enables quick turnaround on repairs, whether for full overhauls, smaller cable fixes or on site technical assistance. Kelsey adds that carefully managed local stock levels ensure critical spare parts are readily available, helping mines minimise downtime and maintain operational continuity.
