3.1.1 Drive
The drive of the vacuum pump is carried out coupling-free in "Cantilever design". Due to the motor de-
sign, the vacuum pump is compact, hermetically sealed and also has a high efficiency. The frequency
converter takes over the control of the vacuum pump and permits the adjustment of the speed to the
actual process requirements (in the valid speed range).
