ZWL direct-coupled self priming non clogging sewage drainage pump

ZWL type direct-coupled self-priming sewage pump is a new structure pump developed on the base of ZW self priming sewage pump. The pump has the performance of self-priming and non-clogged sewage drainage and is directed coupled to the motor.

Self priming structure is for the axial back mixing type and through the unique design of the pump body and impeller flow channel.

The pump can be like general self-priming centrifugal pump. It does not need to install the bottom valve and irrigation water diversion and it can suck and discharge the liquids which contains larger particles, solid or long fiber etc. impurities.

ZWL self priming sewage pump can be widely used in municipal drainage project, studied the breeding, light industry, papermaking, textile, food, chemical, electric power, chemical media such as fiber, paste and mixed suspension etc. impurity pump.

Compared with similar domestic ZW self priming sewage pump, ZWL pump adopts a direct connection structure, which has the advantages of simple and compact structure, less vibration, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy to use and maintain.

Operating conditions

1, chemical pump environment humidity 50℃, medium temperature 80℃, special requirements up to 200℃.

2. The PH value of the medium is 6-9 for cast iron and 2-13 for stainless steel.

3. The medium weight shall not exceed 1240 kg/m3.

4. The self-priming height shall not exceed the specified value of 4.5-5.5m, and the length of the suction tube shall be 10m.

5. The diameter of suspended particles is 60% of the pump diameter and the fiber length is 5 times of the pump diameter.


1. Compact structure. This series of horizontal direct-coupled self-priming pump is for horizontal structure, machine pump integration, beautiful appearance, less floor area, compared with the ordinary self-priming pump, reduce the floor area by 30%.If IP54 outdoor motor is used, no pump room is required and can be used outdoors.

2. Stable operation, low noise and high concentricity of components. The direct connection between motor and pump simplifies the intermediate structure and increases the smoothness of operation. The impeller has excellent static and static balance, no vibration during operation, low noise, prolonging the service life of the bearing and improving the service environment.

3. The shaft seal is made of high-quality mechanical seal, and the dynamic and static rings are made of hard alloy, which are wear-resistant, leak-free and have a long service life.

4. Advanced hydraulic model is adopted with high efficiency and good performance.

5. Easy installation, use and maintenance. It does not need to install check valve in the discharge line, and no need to install bottom valve in the suction line, thus simplifying the pipeline system and improving the working conditions.

6. Unique structure and good self-priming performance, only need to ensure that there is quantitative priming fluid stored in the pump body before work.
