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.
