3.1 Function
The rotary vane pumps on the SmartVane line are single-stage, oil-sealed rotary positive displacement
pumps with air cooling and circulatory lubrication. A non-return valve in the vacuum connection closes
the intake line automatically when the rotary vane pump is switched off and prevents an operating fluid
return flow. The integrated oil mist filter cleans the conveyed gas and prevents the operating fluid mist
from being emitted at the exhaust.
The pumping system is made up of the housing, the eccentrically mounted rotor, and the centrifugally
sliding vanes, which divide the suction chamber into multiple chambers. The volume of each chamber
changes periodically as the rotor rotates. This causes the gas to be continuously drawn in at the vac-
uum connection and compressed in the suction chamber by the rotation of the rotor until the exhaust
valve opens against the atmospheric pressure and the gas leaves the suction chamber.

pumps work.

3.1.1 Drive
The vacuum pump is equipped with a highly efficient synchronous motor with sensor-free control, in ac-
cordance with the patented INFORM procedure according to Prof. Schrödl.
The integrated electronic drive unit permits the control and monitoring of pumping functions via the "re-
mote" interface using a display and control panel.
