What is a Self-priming Pump

A Self-Priming pump is designed to be able to lift fluid from below its suction without the need of a foot valve, or hydraulic column of fluid in the suction line. The pump operates with the aid of fluid in the pump volute. The self-priming pump uses an intelligent internal design that recirculates the existing water in the volute which evacuates the air out the discharge or the air release valve.

This continually creates a low pressure zone at the eye of the impeller which draws the fluid up the suction line until eventually the suction line and pump volute are full of the fluid. When they are full of fluid, which then allows the pump to work in dynamic operation similar to a standard centrifugal pump principle.
