The self-priming pump
The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming capacity. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that there is a certain amount of liquid in the pump. Self priming pumps of different materials can be used for different liquids.
The working principle of self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before starting the pump. After startup, the high-speed rotation of the impeller causes the water in the impeller channel to flow to the volute. At this time, a vacuum is formed at the inlet to open the inlet check valve. The air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
