Installing The High Vacuum Flange
– In case the rotor blocks suddenly, torque levels up to
882200 N
Nm
m can occur which need to be absorbed by the
system and the high vacuum flange.
If the pumps are secured with the attachment of
ISO-K flange to ISO-F or with the attachment of
ISO-KF flanges it can come to twisting the flan-
ge in case the rotor blocks suddenly.
– For installing the turbomolecular pumps to the high
vacuum flange, the components listed in the following
m
mu
usstt be used exclusively. Otherwise the turbomolecular
pump may twist or tear off. The clamps, bolts, nuts and
centering rings are special designs from Pfeiffer Vacuum
– The minimum strength of 170 N/mm
2
of the flange material
needs to be observed.
Installation is done as follows:
ISO-K flange with ISO-K flange
For installing the following components are available:
