Lubricated pumps

Pompe lubrificate

Oil lubricated vacuum pumps consist of a rotor with grooves in which vanes are inserted, all placed inside a rotor chamber. As the rotor rotates, the vanes emerge from their seat and lap the chamber, forcing the air into smaller and smaller volumes and thus creating a vacuum.
Unlike dry pumps, there is a ring of oil inside the chamber, food-grade or synthetic depending on the application, which allows the system to be more tightly sealed and therefore provide better vacuum performance, from 0.5 to 400 mbar.
In addition, the presence of oil makes it possible to work in humid environments where water vapours may be sucked in.

The main areas of use are: vacuum packaging, thermoforming, glass and marble processing, medical equipment, food or clay paste extruders.
