Motor regulating sleeve:rubber.

Structure feature


Pump:The pump is installed on the upper part of the pump units.It's centrifugal and has water lubricated bearing mounted with the motor shaft by a joint.


There is a check valve on top of the pump which could prevent rapaid inverse rotation from backword flow.The pump unit should be immersed below the dynamic water lever when in using.


Motor:The motor is installed under the pump.


It is a water filled in hermatical structure.The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.


The motor bearing is water-lubricated.The inner motor contains clean water to cool the water body and the bearing.


The rubber diaphgram adjusts the pressure change caused when temperature rises.

There is a sand resistance system in the upper part of the motor.
