Technology and features
Operating principle
Roots vacuum pumps, also known as vacuum boosters, belong to the dry-running vacuum pumps. Together with a backing pump they cover a wide range of applications in which high pumping speeds are required. The two Roots rotors operate entirely without contact and without sealing liquid in the pump chamber; on most models only the timing gears and bearings are oil-lubricated.
The technology page shows the operating principle with an interactive drawing: Roots vacuum pumps.
Features of the series
- Three-phase motor of efficiency class IE3, flange-mounted; without motor on request
- Integrated bypass (pressure equalisation valve): switch-on at atmospheric pressure together with the backing pump, protection against thermal overload
- Air-cooled, no utilities required
- Robust bearing arrangement for smooth running, long maintenance intervals
- Vertical or horizontal gas flow, conversion on site possible
- Dry-running Roots principle: oil-free pump chamber, gear chamber and pump chamber separated by radial shaft seals
