The pump operates with the aid of fluid in the pump volute. The Food grade 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 principal.

Applications for Self-Priming Pumps

Self-priming electric water pumps are used in petrochemical, mining, water management, effluent and sewage processing, agricultural and industrial wastewater applications.

Types of Self Priming Pumps

Centrifugal Pump

Dosing Pump

Positive Displacement Pump

Centrifugal Pump

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.

Common uses include water, sewage, agriculture, petroleum and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.
