1.The impeller structure with unique single -or dual- blade, which greatly improving the dirt capacity, can effectively by five times the fiber material and pump diameter pump diameter of about 50% solids .

2, the mechanical seal with anticorrosive hard tungsten titanium material enable secure more than 8000 hours of continuous operation .

3, the overall structure is compact , small size , low noise, energy-saving effect is remarkable , easy maintenance, no need to build pumping stations, dive into the water to work , greatly reducing the construction cost.

4, QW (WQ) type non-clogging submersible sewage pump seal oil chamber with high precision interference leakage detection sensors embedded in the stator windings of the thermal components, the pump motor automatically protected.

5 , It can be equipped with automatic control cabinet according to user needs, the pump leak , leakage overload and overtemperature automatic protection , improved product safety and reliability

6, the float switch can change according to the required level , automatic control of pump start and stop , without special care , extremely easy to use .

7, QW (WQ) type non- clog submersible sewage pumps can be fitted with automatic coupling installation requires a dual rail system , it gives installation and maintenance to bring greater convenience , may not have to get into the sump .

8 , it is possible to use the whole head , and ensure the motor is not overloaded .

9 , there are two types of installation , fixed automatic coupling installation system, mobile free installation system
