Screw Pump

1. Brief introduction and structure The main technical performances of the pump approached the advanced level of develop countuy tor same kind products 1. High efficiency the efficiency of pump unit is higher than the centrifugal submersible pump 5% within the rated head range. The obvious effect is saving energy. 2 Small diameter of the pump casing is convenient for customer application. OG series sand-proof small size submersible 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. 2. Structure description OG series of a sand-proof small size submersible 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 pump and submerged in water, so the heat dissipation effect is very good.
