Submersible deep water suction pump

Product Application

QJ series deep well pump is directly connected with motor, which applies to groundwater extraction from deep wells. It can also be used in rivers, reservoirs, canals and other water projects. It's mainly used for irrigation and the mountain plateau drinking water and also for the cities, factories, railways, mines, construction sites for drainage and water supply.

Main Features

a) Submersible motor adapts water-filled wet structure, internal chamber was filled with water for cooling the motor and lubricating the bearing.
b)For preventing the sand getting into the motor, the sand-preventing unit including sand slinger and skeleton oil-sealed was installed in the upper part of motor, the whole motor was sealed tightly.
c) There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part.
d) There are thrust bearing and thrust collar, mainly for sustaining remnant axial force of pump and the empty weight of motors rotor.
e) The winding of motor stator adopts water-proof electromagnetic wire with good insulating and water-proof functions and rotor adopts squirrel-cage structure.
