NEW Leybold WAU-501 Standard Series Roots Blower Vacuum Pump, 3-Phase, 208-230/460 VAC 60 Hz NEMA Motor, Requires LV 100 Standard Oil, LV PN 11731
The Leybold WAU 501 WAU-501 HYRDOCARBON OIL standard series Root's blower vacuum pumps are driven by air cooled motors. They have shaft seal feedthrough to the atmosphere and the pump is coupled to the air cooled motor . The WAU pumps are easy to operate! They include a pressure differential valve that allows them to be started at the same time as the roughing pump.
In the event of an excessively high pressure difference between the flanges, the valve will open. Then a part of the pumped gas will flow
through this line back to the intake flange. Therefore the pump may be
switched on together with the backing pump at atmospheric pressure.
This increases the pumping speed of the pump combination also at high intake pressures.
