In the case of a sudden jam of the turbopump rotor, the resulting torque must be taken up via the pump-
ing station frame by the fixture provided by customer. To secure the HiCube 300 Eco pumping station
and connected systems, it is essential to anchor the pumping station.

Required aids
● 2 x lashing straps of adequate length and loading capacity; approximately 3 cm wide
● On-site attachment points to retain the lashing straps
Secure HiCube 300 Eco against twisting
1. Always attach the HiCube 300 Eco pumping station to the two mounting hooks with lashing
straps.
2. Affix the lashing straps perpendicularly to the mounting hooks opening, i.e., against the turbo-
pump rotation direction.
3. Make sure that the belts are fitted and tensioned correctly. Make sure that the belt loop is in the
hollow of the mounting hook.
4. Attach the lashing straps at the customer site so that they are able to withstand loads of up to
2000 N per attachment point.
5.4 Connecting the high vacuum side
5.4.1 Designing the counter flange
NOTICE
Risk of damage due to incorrect counter flange design
Unevenness on the operator-side counter flange results in stresses in the vacuum pump housing,
even when properly attached. This can produce leakage or negative changes in running characteris-
tics.
► Adhere to the shape tolerances for the counter flange.
► Observe the maximum flatness deviations over the entire surface.
Superstructural parts
Installing vertical superstructural parts to the high vacuum connection is the respon-
sibility of the operating company. The loading capacity of the high vacuum flange is
specific for the turbopump used. The total weight of superstructural parts must not
exceed the maximum values specified.
If the rotor is suddenly blocked, the torques arising from the system and the high vacuum flange must
be absorbed. The installation elements for turbo pumps are special designs by Pfeiffer Vacuum.
