Choosing Between Liquid Ring Vacuum & Dry Screw Pumps .

Design & Operation. Dry screw and liquid ring vacuum pumps are rotating positive displacement pumps, but they have differences. The dry vacuum pump does not use fluids to create a vacuum, while the liquid ring does. Dry screw pumps create a vacuum through the rotation of two screw rotors, arranged in parallel, rotating in opposite directions.
