ZWL Self priming sewage wastewater pump

The pump body of ZWL self-priming sewage wastewater pump is built with a liquid storage chamber, which is communicated with the working chamber of the sewage pump through the upper reflux hole and the lower circulation hole, forming the axial reflux external mixing system of the pump. After the sewage pump stops working, there is a certain volume of liquid stored in the pump chamber. When the sewage pump starts, the liquid storage in the pump under the action of the impeller, entrainment of air is thrown up, liquid gas-liquid separation pipe is backflow to the working chamber, the gas is discharged from the sewage pump, so that a certain vacuum degree is formed in the pump to achieve the performance of self-priming.
Features:
The sewage pump need not install check valve on outline pipeline and foot valve/bottom valve onto inlet pipeline. Before the pump works, it is ok for some liquids to store into pump body. ZWL sewage wastewater pump is easy for installation and maintenance.
The anti-winding and non blocked impeller with big flow channel can pass the fluids with solid particles or fiber impurities etc and pump is not clogged.
Compact structure, horizontal pump and motor is directly connected to have, beautiful appearance, less floor area. Compared with the ordinary self-priming sewage pump, the floor area is reduced by 30%
Smooth operation, low noise, high concentricity of components. The direct connection between the motor and the pump simplifies the intermediate structure and increases the stability of operation. The impeller has excellent static and static balance, no vibration during operation, low noise, prolongs the service life of the bearing and improves the service environment.
3. Advanced hydraulic model is adopted, featuring high efficiency and good performance.
Advantages:
Compact structure, less vibration, good self-imbibition performance, strong sewage capacity, high efficiency and energy saving, easy to use and maintain
ZWL Self priming sewage wastewater pump is used to transport the liquids with big solid particle, long fiber, sediment, impurities etc
