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 regard.
Required tools
● Hexagon wrench (13 WAF)
● Calibrated torque wrench (tightening factor ≤ 1.6)

Flange connection ISO-K with ISO-F, hexagon head screw and tapped hole
Connection of the hexagon head screw and tapped hole
1. Only use the approved mounting kits of Pfeiffer Vacuum for the connection of the turbopump.
2. Place the collar flange over the high vacuum flange of the turbopump.
3. Insert the snap ring in the side groove on the high vacuum flange of the turbopump.
4. Attach the turbopump with collar flange, snap ring and centering ring to the counter flange accord-
ing to the figure.
5. Use all prescribed components for the turbopump.
6. Screw the hexagon head screws into the tapped holes.
– Observe the minimum tensile strength of the flange material and the screw depth.
7. Fasten the hexagon head screws cross-wise in 3 steps.
– Tightening torque:
5, 10, 16 ± 1 Nm
