The working principle of the liquid ring vacuum pump is to achieve gas suction and compression through the interaction between the rotor and the liquid ring, using centrifugal force and the sealing of the liquid ring. This pump has a wide range of applications and important industrial value.

Double-suction pumps have been widely used and recognized in the engineering field for their unique double impeller design, horizontally split pump casing, smooth operation, compact structure, and high-quality seals and bearings.
