The Leybold Sogevac SV300 SV 300 single stage oil sealed vacuum pump is designed for continuous operation over the working pressure range from atmosphere to less than 1 Torr.The Oerlikon Leybold WSU 501 WSU-501 Root's blower vacuum pumps are driven by an air-cooled canned motor, the term canned means that the blower's electric motor operates inside the pump's vacuum region. In the canned motor design, the motor's rotor operates on the drive shaft of the pump inside a vacuum-tight can made of a nonmagnetic material. The motor's stator slides over the outside of the vacuum tight can and operates in air. This canned electric motor design allows the WSU blowers to be particularly leak tight and operate without the need for shaft seal which would be subject to wear. For these reasons the Oerlikon Leybold WSU blower vacuum pumps are often used in vacuum processes which require evacuation of chemical process gases. 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. When pumping at high pressures near atmosphere excessive pressure will build across the blower, this will cause the differential pressure valve to open, and part of the pumped gas will cycle back to the intake flange. This allows for improved pumping speed even at high intake pressures now that the blower and backing pump can operate together over the full pumping range. These Oerlikon Leybold RuVac WSU501 WSU 501 Root's blower booster vacuum pumps have ISO-63 inlet and exhaust flanges, have a pumping speed of 318 cfm, and have been rebuilt for oxygen save and chemical resistant PFPE vacuum pump oils, such as, Fomblin and Kyrtox (chemical resistant LVO-400 oil). The WSU-501 blower was factory oriented to operate with vertical flow. These WSU-501 pumps can be rotated to operate in either directionsthis is one integrated packagePump came out of a working plant that downsized.We can put it on a skid and load to your truck free or for a fee of $35 palletize it and load your common carrierAdditional Prep Fees May Apply
