: Product Overview :


    QW (WQ) non-blocking submersible sewage pump is a new generation of pump products developed on the basis of the introduction of foreign advanced technology and the use of domestic water pumps. It has significant energy-saving effects, anti-winding, non-blocking, automatic installation and Features such as automatic control. Unique effect in discharging solid particles and long-fiber waste.
This series of pumps adopt unique impeller structure and new mechanical seals, which can effectively transport solids and long fibers. Compared with the traditional impeller, the impeller adopts the form of single flow passage or double flow passage. It is similar to a curved pipe with the same cross-section size. It has very good flow characteristics and is equipped with a reasonable volute to make the pump efficient. The dynamic and static balance tests of the high and impellers make the pump vibration-free during operation.     
   1. The unique single-plate or double-blade impeller structure greatly improves the ability of dirt to pass, and can effectively pass 5 times the fiber diameter of the pump and solid particles with a diameter of about 50% of the pump diameter.

2 . The mechanical seal adopts new hard and corrosion-resistant tungsten tungsten material, which can make the pump run continuously for more than 8000 hours .

3. The overall structure is compact, small in size, low in noise, significant in energy-saving effects, convenient for maintenance, no need to build a pump room, and it can work when submerged in water, greatly reducing project cost.

4. The pump sealed oil chamber is provided with a high-precision anti-interference water leakage detection sensor, and a thermal element is embedded in the stator winding to automatically protect the pump motor.
5. Can be equipped with a full-automatic control cabinet according to the user's needs to automatically protect the pump from leakage, leakage, overload and over-temperature, which improves the safety and reliability of the product
6. The float switch can automatically control the start and stop of the pump according to the required liquid level change. It does not require special supervision and is extremely convenient to use.
7. The QW (WQ) series can be equipped with a dual-rail automatic coupling installation system according to user needs, which brings greater convenience to installation and maintenance, and people do not have to enter the sewage pit for this purpose.
8. It can be used in full head without any overload of the motor.
9. There are two different installation methods, a fixed automatic coupling installation system and a mobile free installation system.
Second, the main purpose:

Suitable for chemical industry, petroleum, pharmaceutical, mining, papermaking industry, cement plant, steel plant, power plant, coal processing industry, and urban sewage treatment plant drainage system, municipal engineering, construction site and other industries. Also used for pumping clean water and corrosive media.
