U4 series

Rotary vane vacuum pumps, oil-lubricated

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 U4 series pump comes standard with:

Most efficient IE3 motors in the industry
Non return valve
High efficiency oil separator element
