QW submersible sewage pump

The WQ (QW) series submersible non clogging sewage pump has been successfully developed through the joint efforts of our research personnel and extensive solicitation of opinions from domestic water pump experts. After multiple improvements, its performance indicators have reached the level of similar products through testing.
Flow rate: 7-2400m3/h, head: 7-60m, etc., designed and manufactured into WL, YW, GW series products with the same energy parameters according to different media and installation methods.

Product Features
1. By adopting a unique single or double disc wheel structure, the ability of dirt to pass through is greatly improved, which can effectively pass through the fiber material with a diameter of about 50% of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump.
3. The overall structure is compact, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and there is no need to build a pump room. It can work by diving in, greatly reducing the project cost.
4. The pump is equipped with a high-precision interference leakage detection sensor in the sealed oil chamber, and a thermal sensor is embedded in the stator winding to automatically protect the water pump motor.
5. According to user needs, a fully automatic control cabinet can be equipped to automatically protect the pump from water leakage, electric leakage, overload, and overheating, improving 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 changes, without the need for special supervision, making it extremely convenient to use.
7. The 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.
8. It can be used within the full head without overloading the motor.
There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.

Main purpose
Suitable for conveying granular sewage and waste in industries such as chemical, petroleum, pharmaceutical, mining, papermaking, cement plants, steel mills, power plants, coal processing, as well as drainage systems of urban sewage treatment plants, municipal engineering, construction sites, etc. It can also be used for pumping clean water and corrosive media.
