SIDE CHANNEL VACUUM PUMPS

Side channel vacuum pumps have had their uses for decades reliability proven in the service area - through convincing performance and almost maintenance free, day in and day out, with virtually no downtime. For years, side channel vacuum pumps quieter than most other vacuum pumps and compressors. We offer a wide range of accessories that are ideally suited to these pumps, thus improving their performance and adapting to the specific needs of customers. The pumps can too installed outside and thanks to their special soundproofing even in sensitive environments, such as schools and residential areas and even hospitals, come into operation.

Gas escapes via the intake port (D) a. The impeller in some pumps is mounted directly on the motor shaft for non-contact compression, resulting in increased durability. When the gas enters the side channel (A) occurs, the rotating impeller (B) spirally accelerated in direction of rotation. The effect of centrifugal force ensures that the gas in the impellers (B) is accelerated radially outwards and the pressure is increased. With each re-entry into the impeller, kinetic energy is fed back to the impeller along the side channel. The cross-section of the side channel decreases at the interrupter, the gas is scraped off by the impeller and leaves the pump through the outlet opening (C). A high degree of operational safety and a long service life, even with high differential pressures, is guaranteed by the arrangement of the bearings outside the compressor chamber.
