Weir Minerals Africa reported a Warman MCR 450 pump increased the throughput and reduced energy consumption in the secondary mill circuit at Anglo American Platinum's Mogalakwena mine. Weir originally proposed the pump solution, equipped with a rubber lining and metal impeller, because it offered a higher volumetric capacity. The larger impeller allows lower pump speeds. The rubber liner is lighter, and the hydraulic design has improved efficiency and wear characteristics, Weir reported.
