Application of Liquid Ring Vacuum Pump

Vacuum is very much a part of industrial life today and it is difficult to conceive of any chemical or process plants where vacuum is not used to increase the efficiency of the process. The applications of vacuum are increasing daily with advances in technology.

In some of the operations vacuum is used so that the reaction can be carried out at a lower temperature with beneficial effects on the end products while in other operations vacuum is used to provide the necessary difference in pressure to carry out the operation.
