NEW HYDROCARBON OIL Oerlikon Leybold RuVac WSU-251 WSU 251 Blower Booster Vacuum Pump, HYDROCARBON LVO-100 OIL, PN 11723
The Oerlikon Leybold WSU 251 WSU-251 HYRDOCARBON OIL standard series Root&＃39;s blower vacuum pumps are driven by air cooled motors. They have no shaft feedthrough to the atmosphere, thus the Oerlikon Leybold WSU 251 WSU-251 is particularly leaktight. In the canned motor, rotor and stator pack are separated by a vacuum-tight can made of a nonmagnetic material. The rotor operates on the drive shaft of the pump in the vacuum, so that a shaft seal which would be subject to wear is not required. The WSU 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. These Oerlikon Leybold WSU 251 WSU-251 ?are chemical series pumps being prepare from the factory with HYDROCARBON LVO-100 standard vacuum pump oil. These blowers are stock items and typically can ship instantly from our warehouse and have Oerlikon Leybold part number 11723.
The price for the pump listed is for a Oerlikon Leybold WSU 251 WSU-251 blower booster HYDROCARBON standard LVO-100 oil prepared vacuum pump only, backing pumps are extra. We also sell mechanical and blower vacuum pump systems. Please call (505) 872-0037 for more information.?
