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.
3.1.2 Cooling
● Air cooling
The electronic drive unit regulates the cooling capacity of the integrated fan depending on the cooling
requirement.
3.1.3 Shaft bearing
Ball bearing-mounted eccentric shaft. The dry running working chamber of the vacuum pump is separat-
ed hermetically from the shaft bearing.
● 2 x deep groove ball bearings, maintenance-free
3.1.4 Gas ballast
Depending on the pump version, the vacuum pump has a gas ballast system for manual or automated
supply of inert gas to the suction chamber. Gas ballast supports the reduction of condensate accumulat-
ing in the pumping system. Pumping explosive atmospheres when using the automated gas ballast
valve is not permitted as the electromagnetic valve does not have ATEX approval.
3.1.5 Pressure sensor
The retrofittable RPT 010 digital pressure sensor with piezo/Pirani sensor measures the vacuum
pump’s intake pressure and extends functionality, for example with pressure regulation operation.
Pumping explosive atmospheres when using the pressure sensor is not permitted, as the sensor does
not have ATEX approval.
