U.S. Vacuum LRH “K” series pumps are dual stage liquid ring vacuum pumps capable of producing a vacuum to 29” Hg. 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. 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. Call US Vacuum for assistance.
