Product Overview

WQ type non clogging submersible sewage pump is a new generation of pump product successfully developed on the basis of introducing foreign advanced technology and combining the use characteristics of domestic pumps. It has the characteristics of significant energy-saving effect, anti winding, non clogging, automatic installation and automatic control. It has unique effect in discharging solid particles and long fiber garbage.

This series of pumps adopts a unique impeller structure and a new type of mechanical seal, which can effectively transport solids and long fibers. Compared with the traditional impeller, the impeller of the pump is in the form of single channel or double channel, which is similar to a bend with the same section size, and has very good flow passing performance. With a reasonable volute chamber, the pump has high efficiency, and the impeller has passed the dynamic and static balance test, so that the pump has no vibration in operation.

The hydraulic performance of the pump is advanced and mature, and all performance indicators of the product have reached the relevant standards after testing. After the product is put on the market, it is welcomed and praised by the majority of users for its unique efficacy, reliable performance and stable quality.

1. The design of anti clogging hydraulic components with large flow passage is adopted, which greatly improves the passing capacity of dirt, and can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump mouth.

2. The design is reasonable, the supporting motor is reasonable, the efficiency is high, and the energy-saving effect is remarkable.

3. The mechanical seal adopts double channel tandem seal, and the material is hard corrosion resistant tungsten carbide. It is durable and wear-resistant, 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 and install. It can work underwater without building a pump room, greatly reducing the project cost.

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

6. Full automatic safety protection control cabinet can be equipped according to the user's needs to monitor the water leakage, electric leakage, overload and overtemperature of the pump, so as 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 need to enter and exit the sump for this purpose.

8. The float switch can automatically control the stop and start of the pump according to the required water level change, without the need for special personnel to take care of it.

9. Ensure that the motor runs without overload within the range of use lift.

10. The water jacket external circulation cooling system can be used for the motor according to the application situation, which can ensure the safe operation of the electric pump in the anhydrous (dry) state.

11. The installation methods include fixed automatic coupling installation and mobile free installation, which can meet different application occasions.
