Self Priming Centrifugal Water Pump
Product Description
A self-priming centrifugal pump is a type of centrifugal pump that eliminates the need for priming before its initial use. This remarkable pump can effortlessly remove any gas present in the suction pipe and continue efficiently transferring liquids without requiring priming whenever it is restarted.
The pump incorporates an additional suction chamber positioned at the inlet, with the suction pipe located above the impeller's center line. Even after the pump is switched off, some of the liquid remains trapped in the suction chamber. When the pump is restarted, the liquid present in the suction chamber circulates within the pump and effectively draws in any gas present in the pipeline. As the impeller operates, the gas and liquid are mixed either internally within the impeller or externally at the impeller outlet. They subsequently enter a gas-liquid separation chamber installed at the outlet to effectively separate the gas from the liquid. The separated gas is then expelled from the pump, while the liquid flows back into the suction chamber until the suction pipe is entirely filled with liquid. This process ensures the normal delivery of liquid. Remarkably, the self-priming process can be accomplished in a matter of seconds, with the self-priming capacity boasting an impressive capability of surpassing 9 meters in water column height.
