Mounting orientation
When using dry backing pumps, Pfeiffer Vacuum HiPace pumps are designed for instal-
lation in any orientation.
Support pipes in front of the vacuum pump or remove them. No force from the pipe
system may be exerted on the fixed pump.
To avoid contamination via the fore-vacuum line when using oil-sealed backing pumps
the fore-vacuum flange should always point vertically downward (± 25°).

Recommended orientation of the fore-vacuum flange
The maximum axial loading capacity of the high vacuum flange is 1000 N (equals
100 kg). A one-sided load on the high vacuum flange is not permitted.
