Table 7: Permissible forces and torques on pump flanges
If not all working loads reach the maximum permitted values, one of these loads may exceed
the normal limit value. Provided 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.

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.
For higher temperatures, the values must be corrected as follows depending on the ratio of
their modulus of elasticity:
E / E
t, EN-GJL 20, EN-GJL
E = Modulus of elasticity grey cast iron at the selected temperature
t, EN-GJL
E = Modulus of elasticity grey cast iron at 20 °C
20, EN-GJL
Check whether the pump complies with the specifications on the delivery note; report any
damage or missing parts to Wilo immediately. Check slatted crates/boxes/wrapping for
spare parts or accessories that could be included with the pump.
WARNING
Risk of personal injury and property damage due to improper
handling!
• Install only after completion of all welding and soldering work and
after the pipeline system has been flushed, if required.
– Dirt can cause the pump to fail.
