SIDE CHANNEL VACUUM PUMPS

Side channel vacuum pumps have proven their reliability in service for many decades, performing flawlessly virtually maintenance free day in and day out with practically no down time. Side channel vacuum pump for years now have had lower noise levels than that of most other vacuum pumps and compressors. We offer a wide range of accessories that are ideally suited for these pumps thus improving and adapting their performance for your specific needs. These pumps can even be installed outside, and due to their special sound protection, they can operate in sensitive environments such as schools, living quarters and even hospitals.

Gas enters through the inlet port (D). The impeller in some pumps in mounted directly on the motor shaft for contact free operation thus furthermore increasing the pumps life span. As the gas enters the side channel (A), the rotating impeller (B) imparts velocity to the gas in the direction of rotation. Centrifugal force in the impeller blades (B) accelerates the gas outward and the pressure rises. Every rotation adds kinetic energy, resulting in further increase of pressure along the side channel. The side channel narrows at the rotor, sweeping the gas off the impeller blades and discharging it through the outlet port (C). Maximum operational reliability and service life, even at high differential pressures, is ensured by the arrangement of the bearings outside the compression chamber.
