single-phase iron sewage pumps,dirty water pump, surmesible pump,waste water pump

WQ(D) Application

WQ(D) Submersible sewage pump is composed of motor,water pump and sealing part.The water pump has impeller-volute structure, and it is under the single or three phase asynchronous motor.Mechanical seal is used as the motive seal between motor and water pump,and oil reasisting rubber O ring works as the static seal for the rabbet.Thus,the reliability of our machine is ensured.Meanwhile,the rotor shaft is made of stainless steel,so reliable machanical strength of the shaft is obtained,and the abrasion resistance and corrosion resistance of the shaft are both improved.

Also,it facilitates the disassembly and maintenance of impeller.
