WQ
WQ high-power sewage submersible electric pump, implement GB / T24674 standard. The electric pump is composed of water pump, seal and motor. Motor upper the pump, which is three-phase instep motor; the pump is located in the lower part of the pump, which is the flow channel impeller-volute structure; between the pump and motor, double end mechanical seal and single end mechanical seal, and "O" oil-resistant rubber seal ring to ensure the reliability of the electric pump. The rotor shaft of the electric pump uses 45 # steel to ensure that the shaft has a more reliable mechanical strength.
Application
This series of electric pump is widely used in industry, agriculture, mining, civil construction, municipal environmental protection and other places, is the ideal equipment for pumping sediment, ash water, domestic waste water, sewage feces and urine and containing short fiber, paper scraps, sediment and other solid particles and rural drainage and irrigation, river pond dredging.
