Production introduction:
QDX type submersible pump consists of pump, mechanical seal and motor. Pump is at the bottom part of motor pump, which adopts centrifugal impeller. Motor is at the upper part of motor pump and is a single-phase asynchronous motor or 3-phase motor. Mechanical seal is between pump and motor, and it is one kind of double end mechanical seal, "O" rings are applied to all static joints of the submersible pump. Inner-installed protector prevents the pump from the damages due to abnormal power, clog and overload etc.
