Description
Operating principle
R5 rotary vane technology is synonymous with a robust and functional construction. In a cylindrical housing, a rotor with three vanes is mounted eccentrically. Due to centrifugal force, these vanes slide out and form chambers between themselves and the housing.
The pumped medium is trapped inside these three chambers. During further rotation, their volume is constantly reduced. Thereby, the pumped medium is compressed and transported to the outlet.
R5 vacuum pumps operate with recirculating oil lubrication. A downstream oil separator segregates sealing oil and pumped medium for efficient reuse of oil.
A non-return valve prevents the pumped medium from flowing back into the process after the vacuum pump is switched off.
R5 RA
- High performance
- Durable construction
- Designed for continuous operation
- Ultimate pressure proofed
- High performance vanes
Benefits of the R5 RA series
R5 RA oil-lubricated rotary vane vacuum pumps are real all-rounders. They have been designed for a wide range of industrial applications, for example vacuum packaging, food processing, pneumatic conveying, plastics processing and many more.
These vacuum pumps are characterized by high pumping speeds even in low pressure ranges and therefore rapid evacuation times.
They feature highly durable high performance vanes as standard, ensuring excellent performance and a long service life.
R5 RA vacuum pumps are designed for continuous operation. An integrated float valve regulates the oil return depending on the oil level.
Vacuum pumps of the RA series are ultimate pressure-proofed. They can be operated continuously at ultimate pressure without overheating.

R5 RD
The new benchmark of rotary vane technology
- Reduced energy consumption
- Reduced heat emission
- Improved cooling air flow
- Fast service routine
- Smooth surface design
- Highly resilient carbon fiber vanes
Benefits of the R5 RD series
R5 RD rotary vane vacuum pumps are the new standard for vacuum packaging. They are also well-established in a variety of other industrial applications.
High efficiency is the outstanding quality of this series. With an up to 30% lower energy consumption compared to conventional rotary vane vacuum pumps.
Heat emission has also been reduced thanks to an improved cooling air flow. Together with an optimized heat discharge, this contributes to a low ambient temperature.
All service relevant components are mounted on one side of the vacuum pump for easier access. Therefore, the service routine becomes significantly faster. And the smooth surface design facilitates cleaning.
The single exhaust filter can be replaced in less than a minute. Moreover, it provides enhanced filtration performance for best-in-class oil separation.
R5 RD vacuum pumps feature hard-wearing carbon fiber vanes as standard, ensuring excellent performance and a long service life.
