Table 8: Permissible forces and torques on pump flanges in horizontal pipe
If not all working loads reach the maximum permitted values, one of these loads may
exceed the normal limit value. This is under the condition that the following additional
conditions are fulfilled:
ƒ
All force and torque components are limited to 1.4 times the maximum permitted
value.
ƒ
The forces and torques acting on each flange meet the requirements of the com-
pensation equation.
Fig. 15: Compensation equation
Σ F
effective
and Σ M
effective
are the arithmetic sums of the effective values of both pump
flanges (inlet and outlet). Σ F
max. permitted
and Σ M
max. permitted
are the arithmetic sums of the
maximum permitted values of both pump flanges (inlet and outlet). The algebraic signs
of Σ F and Σ M are not taken into consideration in the compensation equation.
