Application QGD 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 a 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.
