QG Series Screw Pump

Brief introduction and structure

This screw pump is a sand-proof small size submersible screw pump that is a patented product of our company.

The main technical performances of the screw pump approached the level of developed country.

The main advantages of the screw pump are as following:

1.High head: the screw pump is provided with wide application range because of its high head.

2.High efficiency: the efficiency of screw pump unit is higher than the centrifugal submersible pump 5% within the rated head range. The obvious effect is saving energy.

3.Small diameter of the screw pump casing is convenient for customer application. QG series sand-proof small size screw pump is widely used for far distance transport water, Irrigation, Spray, High building, factory. Mine and family as water supply pump. Also for cultivation, refrigeration and industry field.

Structure description

QG series of a sand-proof small size screw pump mainly is consisted of submersible motor, single screw pump and seal, single phase or three phase asynchronous motor is dry type or oil-filling type construction. The motor is positioned under the screw pump and submerged in water, so the heat dissipation effect is very good.

The single phase screw pump is consisted of a single helix resilience rubber stator and creates a continuously forming cavity as it rotates.

The motor adopts 0 sealing ring and double end face mechanical steal. Function of seal is reliable and long working life.
