Horizontal mounting orientation
Î
For horizontal installation, the fore-vacuum flange must point vertically down-
ward (± 20°), since otherwise the turbopump can be contaminated.
Î
Support pipes in front of the pump or remove them. No force from the pipe sys-
tem may be exerted on the braced turbopump.
The maximum axial loading capacity of the high vacuum flange is 500 N (equals
50 kg). A one-sided load on the high vacuum flange is not permitted.
Installing the high
vacuum flange
In the case the rotor is suddenly blocked, the torques arising from the system and
the high vacuum flange must be absorbed. Only the components listed in the fol-
lowing can be used to fasten the turbo pumps to the high vacuum flange. The com-
ponents for installing the turbo pumps are special designs of Pfeiffer Vacuum. Ob-
serve the minimum strength of 170 N/mm
2
for the flange material.
CAUTION
Danger from the pump being ripped off
When a Pfeiffer Vacuum vibration damper is used, suitable safety measures must be
taken to compensate for the torques in case of sudden blocking.
Î
Definitely consult with Pfeiffer Vacuum.
Î
Do not exceed the maximum permitted temperature at the vibration compensator
(100°C).
NOTE
Observe type-specific mounting orientations!
Pfeiffer Vacuum CompactTurbo™ pumps may only be installed in specific mounting
orientations. Impermissible mounting orientations can result in contamination of the
process vacuum or damage to the pump.
Î
Pay attention to the properties code after the model designation on the name plate!
