Water ring vacuum pumps are high vacuum pumps used in industries for many applications. A water ring is formed inside the chamber due to rotation of a rotor mounted on the eccentric shaft. These pumps are economical as well as easy in operation and have a long operational life. These pumps are available in the following versions:

| Working Principle |
|
A dynamically balanced cylindrical rotor with a hollow hub and a series of curved blades is rotated freely in the eccentric casing. The sufficient sealing water / liquid forms a solid ring on the periphery of the casing, due to the centrifugal force, the rotor is rotated in the eccentric casing, the rotating blade creates working spaces whose volume increases as the rotor rotates from lower to upper vertex and decreases as the rotor rotates from upper vertex to lower vertex. The uniform distribution of working spaces on rotor periphery results in continuous suction and exhaust of gases. |
