The self-priming 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 it is only necessary to ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use self-priming pumps of different materials.
The working principle of the self-priming pump is that the pump casing is filled with water (or there is water in the pump casing itself) before the pump is started. 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, which makes the water inlet check door open, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
Application range of self-priming pump:
1. Equipped with a rocker-type sprinkler head, the water can be flushed into the air and scattered into fine raindrops for spraying. It is a good machine for farms, nurseries, orchards, and vegetable gardens.
2. The self-priming pump is suitable for clean water, seawater, chemical medium liquid with acid and alkalinity and slurry with general paste (media viscosity <100 centipoise, solid content up to 30%).
3. The self-priming pump can be used with any type and specification of the filter press, and it is an ideal matching pump for the filter press when the slurry is sent to the filter press.
