Oil-lubricated vacuum pumps

Oil-lubricated vacuum pumps are available form FIPA as rotary vane vacuum pumps.


Compact vacuum generators require minimal installation space, they are suited for applications that handle porous products and they achieve an extremely high vacuum level. The integrated oil recovery system minimizes oil vapours in the vacuum supply. An efficient damping system ensures a reduced sound pressure level.


In continuous operation, oil-lubricated rotary vane vacuum pumps by FIPA, like all other wet-running vacuum pumps, should be operated at full load (minimum vacuum level: 99.8 %) in order to prevent oil leaks.

Oil-lubricated rotary vane vacuum pumps are available with single-phase and three-phase connection. The mounting position is horizontal.


Many of the oil-lubricated vacuum pums can be used in humid or dry areas.
