  • OIL-LUBRICATED VACUUM PUMP WITH IMPROVED OIL SEALING
    Publication number: 20250003427
    Abstract: A vacuum pumping system includes an oil-lubricated rotary vacuum pump, an electric motor driving the pump and a gas ballast arrangement supplying the pump with gas and fluidically coupled with the motor for sucking oil, leaked from the pump into the motor, back into the pump. The fluidic coupling is achieved by means of a leaked oil recovery unit that is housed in a region of an internal chamber of the motor where ballast gas and leaked oil are present and that establishes communication between the region of the internal chamber of the motor and the pumping chamber.

  • VACUUM PUMPING SYSTEM HAVING AN OIL-LUBRICATED VACUUM PUMP
    Publication number: 20220235772
    Abstract: A vacuum pumping system includes an oil-lubricated vacuum pump, including a stationary pump stator and a rotatable pump rotor, and a motor, including a stationary motor stator and a rotatable motor rotor cooperating with each other for driving in rotation the pump rotor. The motor further includes an oil-tight unit including a metal jacket enclosing the motor rotor and forming a container intended to collect and keep inside the motor any oil leaking from the pump.
