Liquid ring vacuum pump consists of discharge connection, operating liquid port, inlet connection, impeller, housing, inlet and discharge port and operating liquid. In a liquid ring vacuum pump, the pumped gas or vapour is sucked through the inlet connection into the pump-motor. This is then pushed out through the discharge connection. The impeller is located in the cylindrical housing and is arranged eccentrically concerned to the housing. The housing also consists of the operating liquid. This liquid is then fed in through the operating liquid port and put out with the pumped gases through the discharge connection.

The working stages of this pump are as follows At the upper vertex, the liquid ring pump fills the impeller cells with the operating liquid. During the first half rotation, the ring lifts the impeller hub. This increases the space in the cells resulting in the sucking of pumped gases through the inlet port. This will continue till the impeller moves to the lower vertex. During the second half of the rotation, the liquid ring reaches the hub again. Now the space in the cells reduces resulting in compression of pumped gases and is then pushed out through the discharge port.
