Technical Information

China HDN Series Single Screw Pump:

The Single-screw pump, a type of rotary positive-displacement pump with internal gearing,is mainly composed of a stator with dual spiral chambers and a rotor engaged with the stator in the shaft sleeve. When the rotor is making planet turning movement by circling the axial line of the stator in the stator chamber,the sealed chamber formed between the rotor and stator will make axial displacement along the spiral line of the rotor, which will convey the liquid evenly,continuously and constantly from the suction to the discharge side.
