3.1 Functional properties
The turbopump forms a compact unit with the electronic drive unit and the integrated power supply
pack.
The turbopump is prepared for retrofitting to a temperature management system (TMS). The TMS pre-
vents condensable process residues through controlled heating of the pump housing. The cooling sys-
tem ensures safe and sufficient heat dissipation without energy loss during the heating process.

3.1.1 Cooling
● Water cooling
The electronic drive unit automatically regulates the drive power down in the event of excessive temper-
atures.
3.1.2 Rotor bearing
Hybrid-bearing turbopump
● High vacuum side: wear-free permanent magnetic bearing
● Fore-vacuum side: ball bearing with ceramic balls
Turbopumps from the hybrid bearing HiPace series use ceramic ball bearings for the rotor bearing on
the fore-vacuum side. The operating fluid pump provides a defined lubrication and continuous function-
ing of the ball bearings.
3.1.3 Drive
● Electronic drive unit TC 1200
