    How does a Self-Priming Centrifugal Pump Work?

    A self-priming centrifugal pump has two phases of operation: priming mode and pumping mode. In its priming mode, the pump essentially acts as a liquid-ring pumpChina Pump controllers manufacturers. The rotating impeller generates a vacuum at the impeller’s ‘eye’ which draws air into the pump from th... Read in detail
