PW series full-automatic vortex self- -priming pump is mainly composed of motor, water pump, seal and control system. The motor is an asynchronous motor, and the electric pump impeller structure is a vortex type, with the characteristics of small flow, high lift and good self-priming. The electric pump is equipped with a control system to realize the automatic operation of the electric pump according to the change of water pressure or water flow, that is, open the valve, the electric pump operates automatically, close
the valve, and the electric pump stops automatically without manually turning off the power supply. This series has the function of
stabilizing water supply.
The electric pump has the advantages of small volume, light weight,compact structure, simple and convenient installation. It is an ideal household electric pump with high efficiency, energy saving and safety. It is used to transport clean water without abrasive particles and other liquids similar to water.
