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).
3.1.2 Cooling
The vacuum pump is equipped with water cooling.
3.1.3 Mounting orientations
The vacuum pump is suitable for vertical direction of flow.
