South Africa-based Integrated Pump Technology supplies Grindex submersible dewatering pumps to mining operations in Zambia's Copperbelt, aimed at meeting the needs of tough sludge and slurry removal applications. 

Highlighting the capabilities of Grindex submersible pumps, Integrated Pump Technology sales manager Alfred Kelsey notes the units’ success in applications such as dislodging underground dams. 

Demand for Grindex submersible dewatering pumps is rising sharply across the Copperbelt, notes Kelsey.

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

The Grindex Bravo 400 pump features robust hard-iron construction, abrasion resistance and an integrated agitator. It re-suspends settled material, allowing efficient pumping out of sludge and has an IP68 ingress protection that enables safe operation at depths of up to 20 m.

For higher-capacity Grindex units ranging from 25 kW to 90 kW, the company supplies external control and monitoring panels. Kelsey highlights the pump range's versatility in addressing varying abrasive conditions.

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

The stainless steel construction helps reduce weight which is an advantage for underground operations where pumps often need manual transport and handling. The split handle design also enhances portability, enabling two-person carrying.
