product description

WQ type non-clogging submersible sewage system is a new generation of pump products successfully developed on the basis of introducing foreign advanced technology and combining the characteristics of domestic water pumps. It has remarkable energy-saving effects, anti-winding, non-clogging, automatic installation and automatic control, etc. features. It has a unique effect in discharging solid particles and long fiber waste.

This series of pumps adopts a unique impeller structure and a new type of mechanical seal, which can effectively transport media containing solids and long fibers. Compared with the traditional impeller, the impeller of the pump adopts the form of single flow channel or double flow channel, which is similar to an elbow with the same cross-sectional size and has very good flow performance. With a reasonable volute chamber, the pump has high efficiency. The height and the impeller have passed the dynamic and static balance test, so that the pump has no vibration during operation.

The hydraulic performance of the pump is advanced and mature. After testing, all performance indicators of the product have reached the relevant standards.


1. The anti-clogging hydraulic component design with large flow channel greatly improves the passing capacity of dirt, and can effectively pass through fibrous materials 5 times the diameter of the pump and solid particles whose diameter is about 50% of the pump diameter.

2. Reasonable design, reasonable supporting motor, high efficiency and remarkable energy saving effect.

3. The mechanical seal adopts double-channel series seal, and the material is hard corrosion-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can make the pump run safely and continuously for more than 8000 hours.

4. The pump is compact in structure, small in size, easy to move, easy to install, no need to build a pump room, and can work when submerged in water, which greatly reduces the project cost.

5. There is an oil-water probe in the pump oil chamber. When the mechanical seal on the pump side is damaged and water enters the oil chamber, the probe generates a signal to protect the pump.

6. According to the needs of users, it can be equipped with a fully automatic safety protection control cabinet to monitor the water leakage, electric leakage, overload and over temperature of the pump to ensure the reliable and safe operation of the pump.

7. The double guide rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump, and people do not have to go in and out of the sewage pit for this.

8. The float switch can automatically control the stop and start of the pump according to the required water level change, without special supervision.

9. Ensure that the motor is not overloaded within the range of use head.

10. According to the application occasion, the motor can adopt a water-jacketed external circulation cooling system, which can ensure the safe operation of the electric pump in an anhydrous (dry) state.

11. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage occasions.

Suitable place

1. The discharge of seriously polluted wastewater from factories and businesses.

2. Drainage system of urban sewage treatment plant.

3. Sewage drainage stations in residential areas.

4. Civil air defense system drainage station.

5. Sewage discharge from hospitals and hotels.

6. Municipal engineering and construction sites.

7. Exploration and mining auxiliary machines.

8. Rural biogas digesters for farmland irrigation.

9. The water supply device of the waterworks.
