Self priming pumps do not require water injection, which is the origin of self-priming pumps. Self suction principle of self-priming pump: Due to the special design of the pump casing. Its sealing performance is higher than that of ordinary centrifugal pumps, and the water in the pump casing will not automatically drain after the power is stopped. The power drives the turbine to rotate at high speed, quickly creating negative pressure (vacuum) inside the pump. Utilize atmospheric pressure to pressurize the pump casing, and then centrifuge the head. Suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, dye, printing and dyeing, brewing, electricity, electroplating, papermaking, petroleum, mining, equipment cooling, oil tanker unloading, etc.

Self priming pumps have the advantages of fast power start, smooth operation, low vibration, low fuel consumption, small size, compact structure, stable and reliable ignition. The main uses of self-priming pumps are: automatic booster pumps are used for automatic booster water supply in households with insufficient water pressure, hotels, canteens and high-rise buildings, water towers, solar water heaters, well water and pool water intake, industrial equipment liquid booster circulation, garden watering, and vehicle washing.

Scope of use: flood prevention and drought resistance, road drainage, garden maintenance, greening engineering, irrigation engineering, marine pumping, factory backup, warehouse drainage, etc;

The purpose of a water pump is to transport water from one place to another, or to increase pressure and convert kinetic mechanical energy into liquid energy.

Working principle of water pump: After turning on the water pump, the impeller rotates at high speed inside the pump body (the pump body should be filled with liquid before turning on the water pump). The liquid in the pump body rotates together with the impeller, and under the action of centrifugal force, the liquid is thrown out by the impeller at the outlet. The speed of the thrown out liquid gradually slows down in the diffusion chamber of the pump body. After the liquid is thrown out, a vacuum low-pressure zone is formed at the center of the impeller. The liquid in the liquid pool flows into the water pump through the suction pipe under the action of external atmospheric pressure. The volume of the diffusion chamber of the pump body is constant. As the amount of liquid thrown out increases, the pressure gradually increases and is then discharged from the outlet of the water pump. The liquid is continuously sucked up from the pool and then continuously discharged from the pump outlet
