Understand the main structural features of sanitary self-priming pumps in a few minutes

The sanitary self-priming pump is an efficient and economical centrifugal pump, which meets the sanitary requirements during the processing process, is gentle and does not damage the material, and has chemical resistance
.

Its standard configuration includes housing and pump feet
.

Sanitary self-priming pump is a high-pressure pump designed on the basis of standard centrifugal pump, suitable for high inlet pressure occasions
.

The main structural features of the sanitary self-priming pump are as follows: 1.
There is a rubber valve plate between the water inlet joint and the pump body, which automatically closes when it stops to keep the pump full of liquid for the last introduction
.

2.
The pump is composed of pump body, impeller, shaft, frame, motor and other components, with precise structure and convenient movement
.

3.
Rubber sealing rings are used at the liquid outlet and liquid inlet, and mechanical seals are used for sealing on the rotating shaft
.

4.
The inlet of the pump is equipped with a liquid discharge port.
Twist the cover of the liquid port to open the liquid port, and the liquid material in the pump can be drained
.

5.
There is a gas-water separation chamber in the pump body, which is the same as the outlet, and the water storage chamber is communicated with the return valve
.

When self-priming, the return valve is automatically opened, and the back-flow valve body is equipped with a conical nozzle facing the impeller, which helps to improve the self-priming speed during self-priming
