self priming water pump

Self priming water pump is a type of pump.
The principle is that the pump is filled with water before the pump starts (or there is water in the pump casing).
After the start, the impeller rotates at a high speed to make the water in the impeller channel flow toward the volute.

Description

Self priming water pump is a type of pump. The principle is that the pump is filled with water before the pump starts (or there is water in the pump casing). After the start, the impeller rotates at a high speed to make the water in the impeller channel flow toward the volute. At this time, the inlet forms a vacuum, so that the inlet water stops the door, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. Through repeated cycles, the air in the suction line is gradually drained, and the water enters the pump to complete the self-priming process.

Application

1.self priming water pump is suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, dye, printing and dyeing, brewing, electric power, electroplating, papermaking, industrial and mining washing, equipment cooling and so on.

2. Install the rocker-type nozzle, and then spray the water into the air, and then spray it into small raindrops. It is a good tool for farms, nurseries, orchards and tea gardens.

3. It is suitable for clean water, sea water and chemical medium liquid with acidity and alkalinity and slurry with general paste (media viscosity ≤100 centipoise, solid content up to 30%).

4. It can be used with any type and specification of filter press, and it is the most ideal pump for the filter press to send the slurry to the filter press.
