What is Self-Priming Peripheral Pumps?

Self-Priming Peripheral Pumps are self-priming centrifugal pumps, which have the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, just make sure that there is a quantitative liquid in the pump body before work. Different liquids can use different material self-priming pumps.

The working principle of Self-Priming Peripheral Pumps is to fill the pump casing with water before starting the pump (or there is water in the pump casing itself). After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, so that the water inlet check door opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
