Type HS heavy duty slurry pumps are designed for slurry services. Clean liquid compatible to system liquid is flushed through the inlet port at the back of the motor to prevent the ingress of slurry into the motor area with back flushing line arrangement. The function of this arrangement is to prevent the slurry entering into the rotor chamber. This also lubricates the bearings. An auxiliary impeller located at fore end of the rotor circulates the flushing fluid through an integral heat exchanger to minimize frictional and electrical loss. The back flushing arrangement enables the pump to operate in process fluids with solid continent up to 5%.The back flush should be started at least one minute before switching on the pump and should be allowed to continue for a minute after shutting down the pump.
