Can the pressure switch of domestic self-priming pump be adjusted?

Yes, there are spring screws on the surface of the pressure box of the self-priming pump, which can adjust the required outlet pressure according to the pressure gauge.

Brief introduction of self-priming pump:

Self-priming pump is a kind of self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life and strong self-priming ability. There is no need to install a bottom valve in the pipeline, just ensure that there is a fixed amount of liquid in the pump body to work. Self-priming pumps of different materials can be used for different liquids. The working principle of self-priming pump is to fill the pump shell with water before the pump starts (or the pump shell itself has water). After starting, the impeller rotates at high speed, so that the water in the impeller channel flows to the volute. At this time, a vacuum is formed at the inlet to open the inlet check valve, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
