Compact, reliable and extremely powerful – these are the stand-out features of SECO dry-running rotary vane vacuum pumps and compressors. Due to their lubricant-free operating principle, they can be used in many industrial applications where rapid, clean vacuum or compressed air is required. The SECO family consists of vacuum pumps, compressors and combined vacuum pumps and compressors.

We have continuously developed and optimized our dry-running rotary vane technology for over 30 years. High levels of availability and improved performance are the benefits of this ongoing product advancement.

SECO vacuum pumps and compressors are characterized by their robust construction and lifetime-lubricated bearings.

Operating principle
Inside a cylindrical housing, a rotor with multiple vanes is mounted eccentrically. As the rotor rotates constantly, the vanes slide out and form chambers between themselves and the housing.

The pumped medium is sucked in and trapped inside these chambers. It is compressed through the ongoing rotation and transported to the outlet. Sealing is achieved by self-lubricating high-performance vanes.
