6.3 Permissible forces and torques on
the pump flanges (only PBS pumps) See Fig. 11 and list "Table 3: Permissible forces and torques on the
pump flanges" on page 39.
Values in acc. with ISO/DIN 5199 – class II (2002) – Appendix B,
Family no. 1A.
If not all working loads reach the maximum permitted values, one of
these loads may exceed the normal limit value under the condition
that following additional conditions are fulfilled:
• All force and torque components must be limited to 1.4 times of the
maximum permitted value.
• The following equation applies to the actual forces and torques acting
on every flange (the following condition must be fulfilled):
Where the total load Ǫ F and Ǫ M is the arithmetic total of every
flange (inlet and outlet), for the actual as well as the maximum per-
mitted values, without taking into consideration their algebraic sign,
at the pump level (inlet outlet flange).
