What Is Pump Priming And Self Priming Pump In Details And
A selfpriming pump is designed to increase the water pressure in your home and garden by pumping enough air to suck water through the rotation of the impeller prompting the pump to function A selfpriming pump unlike other centrifugal pumps does not need a gravity feed of water Click here to see Recommended SelfPriming Pumps
A selfpriming centrifugal pump has two phases of operation priming mode and pumping mode In its priming mode the pump essentially acts as a liquidring pump The rotating impeller generates a vacuum at the impellers eye which draws air into the pump from the suction line
The main difference between selfpriming pump and centrifugal pump is that the inlet pipe of selfpriming pump can suck up the water without filling the bottom valve for the first time and no further water is needed later
Standard nonselfpriming centrifugal pumps come in many types When they operate on flooded suction lines or in submersible applications the impeller is surrounded by enough water to create the pressure differential and thus to pump water Air is the main enemy of a standard nonselfpriming centrifugal pump
