The components for installing to an CF-F flange are to be
ordered under the following numbers:
1) supplied pieces
Stud screw with blind hole
➡
If used: Insert the splinter shield and protective screen in
the high vacuum flange with the clamping lugs downward
(towards the pump).
➡
Bring the seal centric into the correct position.
➡
Connect the flanges via 88 pieces of stud screws (M8) with
washers and nuts. The stud screws need to be tightened
revolving with a tightening torque of 22 ±2 Nm. Control the
torque afterwards, because of the sealing material’s
flowing a retightening of the screws may be required.

Connect the flanges via 88 pieces of hexagon screws (M8)
with washers and nuts. The hexagon screws need to be
tightened revolving with a tightening torque of 22 ±2 Nm.
Control the torque afterwards, because of the sealing
material’s flowing a retightening of the screws may be
required.
Directly Flanging The Pump
Only those turbopumps with a "Y" behind the
type designation (please see rating plate, e.g.
TMH 071 Y P) may be fitted in any positions.
Turbopumps in standard version (without “Y”
on the rating plate) can be flanged onto the
vacuum chamber vertically (0°) up to an angle
of 90° maximum.
The fore-vacuum flange must always point
downwards.
CAUTION
CAUTION
CF-F flange
Applications for installing an CF-F to an CF-F flange are “Stud
screw with blind hole” and “Hexagon screw and clearance
hole”. The following items are needed: the particular set of
mounting material and a copper seal. Using asplinter shield or
protective screen is optional.
Don’t touch the copper seal with bare hands,
this may affect the sealings efficiency. See
