US VACUUM™ LRH & LRV SERIES

Coupled Liquid Ring Vacuum Pumps

Two Stage: 15-840 cfm / Single Stage: 32-500 cfm  

 

Liquid Ring vacuum pumps are non-pulsating, centrifugal type pumps available in both Single-Stage and Two-Stage designs, capable of pumping wet process gases and while obtaining pressures down to 25 torr (29″Hg) using water as a seal fluid.

Vacuum to 5 torr obtainable with the addition of an atmospheric air ejector. Link

In the pump, a continuous supply of service liquid, usually water, is required by the pump to carry away the heat of compression and to maintain the liquid ring as some of the service liquid is discharged with the gas through the pump discharge port. Pumps are provided with threaded connections for service liquid, pump draining and vacuum relief valve. Once-thru and full recovery sealant system are available along with Air or Water cooling. Optional items include inlet check valve, vacuum relief valve, flow control, solenoid valve, vacuum and temperature gauges. Various seal liquids may be used depending on the application.
