Product Introduction:

 

QGD Screw Submersible Pump

 

The electric pump is composed of three parts: water pump with screw stem and rubber stator, mechanical seal and a three-phase or single -phase asynchronous motor.
The water pump is installed at upper of the electric pump; the motor is set at bottom of the electric pump; the mechanical seal with double terminal face is between
the water pump and motor. “O” rings are applied in all static joints of the electric pump.

 

 

Applications:

 

The electric pump with multi-stage impellers and high head, is applied to farmland’s irrigation, garden and park’s spraying, pump water from the deep well and drainage, it’s widely used in agriculture, construction, industrial enterprises, mine and environment protection.

 

 

 

 

Work Conditions:

 

The temperature shall not be beyond 40°C, Ph should be between 6.5-8.5.

The volume ratio of solid partial content should be within 0.1% and the size of solid partial must be below 0.2mm.

The power should be 220V (single-phase), 330V (three-phase) and 50Hz, and voltage is allowed to fluctuate between 0.9 to 1.1 times of its rated voltage.

The pump should be fully submerged into water with submerged depth of less than 3.0m and max depth of 5.0m. The pump should be mini 0.5m over the water bottom and not inserted.
