Anchoring the
pumping station
In the case the rotor of the turbopump suddenly blocs, the resulting torque must
be absorbed via the pumping station frame by the fixture provided by customer.
Anchoring the pumping station is mandatory in order to secure the pumping sta-
tion and the vacuum system. For this purpose, there are 4 securing hooks at the
corners of the pumping station frame.
Î
Lock all pumping station roller brakes.
Î
Fasten the pumping station with lashing straps at all 4 securing hooks.
– Pay attention to the fit and the stress of the straps; the strap loop has to be in
the recess of the securing hook.
– Fasten securely the lashing straps provided by customer in order to be able
to hold loads up to 2000 N per anchorage point.
5.3 Connecting the high vacuum side
The assembly of superstructure on the pumping station HiCube Classic is in the op-
erator’s responsibility. The load capacity of the high vacuum flange is specific for
the used turbopump. The gross weight of superstructure on the pumping station
HiCube Classic may
not
exceed 100 kg!
Î
Observe barycentric shifting by using high or lateral protruding superstructure
(e.g. vacuum chamber).
Danger of tilting!
Î
Install the high vacuum flange in accordance with the instructions in the opera-
ting manual of the turbopump.
Î
Ensure the greatest possible cleanliness when installing any high vacuum parts.
Unclean components prolong the pump-down time.
Î
Observe the minimum strengh of 170 N/mm
2
for the flange material.
5.4 Connecting the exhaust side
Î
Prepare the exhaust line provided by customer starting from the pumping stati-
on's casing.
Î
Choose the cross-section of the exhaust line to be at least the size of the nominal
connection diameter of the vacuum pump's exhaust connection.
Î
Piping to the pump must be suspended or supported.

CAUTION
High pressure in the exhaust line!
Danger of damage to the seals and danger of the pump bursting.
Î
Install the line without shut-off valves on the exhaust side.

Pumpe nicht mit Überdruck am Einlass betreiben; max. zulässige Drücke und Druck-
differenzen beachten.
