fill the pump casing with water before starting the pump (or water in the pump casing itself). After the start, the impeller rotates at high speed to make the water in the impeller channel flow toward the volute. At this time, the inlet forms a vacuum so that the inlet water stops the door, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. The self-priming pump is a self-priming centrifugal pump with advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life，, and strong self-priming capability. The pipeline does not need to be installed with a bottom valve. It is only necessary to ensure that the pump body has a quantitative liquid before storage. Different materials can be self-priming pumps of different materials.
