Submersible sewage pump features: 1. Sewage pump with a unique single or double vane impeller structure, greatly improving the ability of sewage through the pump diameter can be 5 times the fiber material and the diameter of the pump diameter of about 50% of the solid Granules. 2. Sewage pump mechanical seal with a new type of titanium carbide hard corrosion, pump safe and continuous operation of more than 8000 hours. 3. The overall structure of the sewage pump is compact, small size, small noise, significant energy-saving effect, easy maintenance, without the need to build pump room, dive into the water to work, greatly reducing project costs. 4.Sewage pump seal oil chamber is equipped with high-precision anti-interference leakage detection sensor, stator winding embedded in the thermal components, automatic protection of the pump motor. 5.Sewage pump can be equipped with automatic control cabinet according to user needs, the pump leakage, leakage overload and over-temperature automatic protection, improve product safety and reliability. 6. Float switch can be based on the desired level changes, automatic control of pump start and stop, without special care, the use of extremely convenient. Imported pump Castel wine valve 7.WQ series can be equipped with double rail automatic coupling installation system according to user needs, it brings greater convenience to installation and maintenance, people do not have to enter the sewage pit for this purpose. 8. Sewage pump can be used in the whole head, and to ensure that the motor will not be overloaded. Sewage pump has two different installation methods, fixed automatic coupling installation system, mobile free installation system. ???????
