WARNING
Risk of injury caused by the turbopump breaking away with the vibration compensator in the
event of a malfunction
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892.
When using a vibration compensator, this will probably lead to the turbopump being sheared off in
use. The energy that this would release could throw the entire turbopump or shattered pieces from its
interior through the surrounding space. Potentially dangerous gases can escape. There is a risk of
very serious injuries, including death, and extensive property damage.
1. Take suitable safety precautions on-site for the compensation of the occurring torques.
2. Before installing a vibration compensator, you must first of all contact Pfeiffer Vacuum.
1. Only install a vibration damper with a vertical passage.
2. Take account of the flow resistance.
3. Secure the turbo pump to the high vacuum flange in addition.
4. Observe the fastening of the ISO-K flanges
(see chapter “Attaching ISO-K flange onto ISO-
(see chapter “Installation of ISO-K flange onto ISO-F”, page 24)
.
5.4.3 Connecting the turbopump externally
Depending on the configuration, the turbopump can be operated independently from the pumping sta-
tion.
Dismantling the turbopump
Please see the descriptions for removing a turbopump from the pumping station
(see chapter “Removing components for maintenance”, page 38)
Procedure
1. Follow the installation instructions for the turbopump in the associated operating instructions for
the individual components.
2. Use cable kit PM 071 477 -T (3 m) from the Pfeiffer Vacuum accessories range.
– Other lengths available on request.
3. Extend the fore-vacuum line and the control cable.
5.4.4 Installation of ISO-KF flange
ISO flange connections
For the connection of flanges in ISO-KF or ISO-K design, twisting may occur in the
event of sudden blockage of the rotor, despite correct installation.
● Leak-tightness of the flange connection, however, is not jeopardized in this re-
gard.
Required tools
● Allen key
● Calibrated torque wrench (Tightening factor ≤ 1.6)

Flange connection ISO-KF to ISO-KF
Using of clamping ring
1. Only use the approved mounting kits from Pfeiffer Vacuum for the connection.
2. Fasten the high vacuum connection on the turbopump and the clamping ring to the counter flange.
3. Utilize all prescribed components for the turbopump.
4. Tighten the clamping ring screws evenly.
