FUNCTION AND FEATURES

QG series of sandproof small size submersible screw pump

is mainly 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 pump and submerged in water, so

the heat dissipation effect is very good.The single screw

pump is consisted of a single helix resilience rubber stator

and creates continuously forming cavity as it rotates.This

cavity which carrying pumped liquid from inlet progresses

towards the discharge end. The motor adopts" o" sealing

ring and double end face mechanical seal. Function of

seal is reliable and long working life.
