  • Less and More : Why You Should Pump Slurries with a Peristaltic Pump

    LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a ...
