Overview

Direct-connected screw pump depends on the screw meshing with the liner on the discharge and suction cavity to convey liquid volume change. It is a method of pressurized screw pump, a central working part by bushing has a double helix cavity (stator) and the stator cavity and its meshing single-head screw (rotor).

Advantage

slight wear and long life;
slight vibration and low noise;
high pressure and efficiency;
Simple structure, easy disassemble and assembly;
small volume and lightweight;
