Vacuum Boosters

Vacuum Boosters

Vacuum boosters are dry vacuum pumps that are used together with backing pumps in all rough and fine vacuum applications where large pumping speeds are required. These pumps operate completely contact-free and without sealing fluids such as oil or water in the working chamber.

Within the housing of rotary lobe vacuum boosters, two lobes rotate synchronously. Due to the special profile of the rotating lobes and their precise manufacturing, they do not come into contact with each other or the housing. This allows for pumping without any operating fluids. A pair of gear wheels located on the shaft ends in the gearbox, and separated from the compression chamber, drive the synchronous rotation of the two lobes.

Rotary lobe vacuum boosters are driven by a direct-drive electric motor. They are offered without a mechanical bypass or with mechanical bypass. Without a mechanical bypass, care must be taken that the maximum differential pressure between the inlet and the outlet is kept during vacuum pump operation. In rotary lobe vacuum boosters with a bypass valve, the differential pressure between the inlet and the outlet is automatically restricted.
