The Influence of Flow Rate on Slurry Pump Selection


Release time:

May 11,2015

The most direct consequence of reduced flow is a decline in the slurry pump’s efficiency and an increase in motor power consumption. Centrifugal pumps are typically designed so that their peak efficiency occurs near the rated operating point.

The most direct consequence of reduced flow is a decline in the slurry pump’s efficiency and an increase in motor power consumption. Centrifugal pumps are typically designed so that their peak efficiency occurs near the rated operating point. When a centrifugal pump operates at a low-flow condition, its efficiency drops rapidly; in general, the lower the flow for a given pump, the lower the efficiency, making operation at low flow highly uneconomical. Under such conditions, it is usually necessary to select and install a suitably sized, high-efficiency small slurry pump.
