Installation and Application
QG type submersible screw pump is mainly composed by three
parts: pump mechanical seals and motor. Pump is at the upper part
of motor pump, which consists by stator and rotator. Motor is at
the lower part of motor pump and is a single-phase or three-phase
asynchronous motor. Mechanical seals is between pump and
motor and it is a kind of double end mechanical seal "O"rings
are oil install static joints of the submersible pump. Inner-
installed protector prevents the pump from damages due to
abnormal power, clog and overload etc.
