product overview
The WQ type non clogging submersible sewage pump is a new generation of pump products developed based on the introduction of advanced foreign technology and the characteristics of domestic water pump usage. It has significant energy-saving effects, anti entanglement, non clogging, automatic installation and automatic control. The effect is significant in the discharge of 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 traditional impellers, the impeller of this pump adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has very good flow characteristics. Coupled with a reasonable volute chamber, the pump has high efficiency and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration.

Product Features
1. Adopting a unique single or double blade impeller structure greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material 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 for more than 8000 hours.
3. The overall structure is compact, small in size, low in noise, and has significant energy-saving effects. It is easy to maintain and does not require the construction of a pump room. It can work underwater, greatly reducing project costs.
4. The pump is equipped with a high-precision anti-interference water 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. A fully automatic control cabinet can be equipped according to user needs to automatically protect the pump from water leakage, 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. 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.

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