Working Principle

The 3G Series Screw Pump operates through intermeshing screw rotors rotating inside the pump casing. As the screws rotate, sealed chambers are formed and move continuously along the axial direction, transporting the liquid smoothly from the suction port to the discharge port. This process ensures stable pressure output and gentle fluid handling with low shear force.
