Self-suction pump

Self-suction pump is a self-priming centrifugal pump, which has 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, and only need to ensure that the pump body has a quantitative priming liquid before work. Different liquids can use self-priming pumps of different materials.
The working principle of the self-priming pump 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 a 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.
