LC 25WR lubricated rotary vane vacuum pump has the same features as LC 25 pump, but it is equipped with a device which split oil and water condensate, being the latter expelled when the pump is stopped. As a result of this construction it is possible to use LC 25WR in applications where very high concentrations of water vapour might be present, and where standard pumps could not be used. The LC 25WR is suitable for continuous suction within a pressure range from 400 to 4 mbar (Abs.)
