PUMPS & VALVES
KSB Pumps and Valves hosted a unique live display of its latest slurry pump technology at Electra Mining Africa 2026 with a fully monitored and adjustable MDX pump circuit that was in operation at regular intervals throughout the duration of the event. Advanced slurry pump demonstration for Electra Mining Africa 2026
The advanced slurry pump display at Electra Mining Africa 2026.
T he demonstration showed how advanced monitoring and adjustment technologies can transform the way slurry pumps are operated and maintained using a live GIW MDX with KSB’s proprietary SLYsight and RAMSL technology that provides the operator with live monitoring data and the ability to set the pump’s liner parameters for optimum performance in the space of minutes rather than hours it would take to perform the same setting on traditional slurry pumps. According to KSB Pumps and Valves market area manager for mining, Jacques Pretorius, the heavyweight unit was brought to South Africa from GIW’s operation in Grovetown, USA in two 20-foot containers and operated using water containing small urethane cylinders to simulate the characteristics of slurry. This allowed visitors to see the pump operating through the transparent piping and heard the particles moving through the pump while also viewing the live data as the settings were
changed. “We wanted to demonstrate to the sub-Saharan African mining industry what technology can achieve, how it can improve performance as well as how it can prolong the lifespan and extend service intervals of pumps in the field. It was the first time that we showed our MDX slurry pump using RAMSL technology which enables quick adjustment of the suction liner to maintain the optimum clearance or “nose gap” between the stationary liner and rotating impeller. This is critical to slurry pump performance as wear can change the gap between it and the impeller as it increases which allows slurry to recirculate around the front of the impeller instead of moving efficiently through the pump. The result is usually reduced hydraulic efficiency and premature component failure. Slurry pumps operate in some of the most demanding environments in the minerals processing chain with abrasive and often highly variable
