U Series
Oil Lubricated Rotary Vane Vacuum Pumps
The robustly constructed rotary vane pumps are suitable for higher pressure differences in vacuum applications. An eccentrically mounted rotor with slots rotates in a cylindrical housing and the precisely fitting sliding vanes move in the slots and separate the individual working chambers. Compared to dry-running rotary vane pumps, oil-lubricated pumps additionally seal the working chambers with the oil that is also transported. The pumps are thus able to generate a fine vacuum and are therefore suitable for applications that require a high vacuum.
Each U Series pump comes standard with:
- Most efficient IE3 motors in the industry
- High efficiency oil separator element
- Oil tank with dual stage oil separation
- Gas ballast valves available
