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:
• All force and torque components are limited to 1.4 times the maximum permitted value.
• The forces and torques acting on each flange meet the requirements of the compensation
equation.
Fig. 16: Compensation equation
Σ F and Σ M are the arithmetic sums of the effective values of both pump flanges
effective effective
(inlet and outlet). Σ F
max. permitted
mitted 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.
Influence of material and temperature
The maximum permissible forces and torques apply for the grey cast iron base material and
for an initial temperature value of 20 °C.
