The working principle of stainless steel screw pump is single spiral rotor stator stator hole of the double helix axis as a planet revolving, sealed cavity is formed between the rotor, stator, deputy continuous, uniform and constant volume will be from the suction end to the extrusion end of medium.

    This  stainless steel pump can transport neutral or corrosive liquid, clean or grinding fluid, containing gas or air bubbles generating liquid, high viscosity and low viscosity liquid, including liquid containing fiber content and software.

    It is a new kind of internal toothing rotary displacement pump.With strong self-priming capacity, the advantages of wide scope of application, for a variety of difficult to transport the pump to transport medium are available. Therefore, stainless steel screw pump in a foreign country is called the universal pump.
