Working Principle: The self-priming pump is an external-mixing self-priming pump. The pump body is provided with a liquid storage chamber (a chamber) , a gas-water Separation Chamber (B Chamber) and a reflux hole. When the pump works, the impeller uses the liquid in the liquid storage chamber to suck the gas in the pump inlet pipeline and separate the gas and water in the gas and water separation chamber. The gas is discharged through the pump outlet. When the pump inlet pipe to a certain degree of vacuum when both the liquid suction up. The pump adopts the back-off structure, no need to remove the pump inlet and outlet pipeline during maintenance. Impeller balance hole to balance the axial force, axial seal can be used packing seal, can also be used a variety of single, double-face mechanical seal.
