A typical self-priming centrifugal pump is generally comprised of a large housing which has several internal chambers and communicating flow passages. Forged Steel Valves Such a housing is constructed to define a suction chamber or reservoir connected to a suction inlet pipe, and a pressure or discharge chamber connected to an outlet pipe.Water Pump Control Valves A volute scroll which defines an impeller chamber including a cutwater is also provided in the housing. An impeller is rotatable within the scroll to establish a suction flow of liquid into the suction chamber through an intake check valve and to force the liquid past the cutwater into the discharge chamber and out of the pump at the desired flow rate and head. WATER POWER CONTROL VALVEAn annular wear plate which defines an internal port is mounted adjacent the impeller, and the liquid is forced through the wear plate port into the eye of the impeller during operation of the pump.
