QW.WQ submersible sewage pump features: 1 using a unique single-leaf or double-leaf structure of the wheel, which greatly improved the living through the ability to effectively pump 5 times the diameter of the fiber material and the diameter of the pump diameter of about 50 % Of solid particles 2. Mechanical seal with a new hard corrosion of tungsten carbide material, the pump can run safely for more than 8000 hours. 3. The overall structure is compact, small size, low noise, significant energy-saving effect, easy maintenance, without building a pump, poured into the water to work, greatly reducing the project cost 4. The pump seal oil chamber is equipped with high precision anti-interference leakage Detection sensors, stator windings embedded in the thermal components, automatic protection of the pump motor. 5. According to user needs with automatic control cabinet, 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. 7.WQ series can be equipped with double 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 sump for this purpose. 8. Can be used in the whole head, and to ensure that the motor will not be overloaded. There are two different installation methods, fixed automatic coupling installation system, mobile free installation system. QW.WQ submersible sewage pump conditions: 1, the medium temperature does not exceed 60 ℃; medium weight 1 ~ 1.3kg / dm3. 2, no self-circulation cooling system of the pump, the motor can not afford to reveal the surface level of 1/3. 3, the use of cast iron material This PH5 ~ 9. 4,1 Cr18Ni9Ti stainless steel is so corrosive medium. 5, the use of the environment Altitude not exceeding 1000 meters, more than the time of order should be made in order to provide you with more reliable products.
