Values in acc. with ISO/DIN 5199 – class II (2002) – Appendix B
Table 5: 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. 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.

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 red brass (RG) 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:

= Modulus of elasticity for red brass at the selected temperature

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.
•
The pump must be protected from the weather and installed in a frost-/dust-free, well
ventilated, oscillation-isolated environment that is not potentially explosive. The pump
must not be installed outdoors! Observe the specifications in "Intended use" section!
•
Mount the pump in a readily accessible place. This makes it easier to complete inspec-
tions, maintenance (e.g. mechanical seal change) or replacement in the future.
Observe the minimum axial distance between the wall and the fan cover of the motor:
free removal dimension of at least 90 mm.
•
Install a device for attaching hoisting gear above the set-up site of the pumps. Total
weight of the pump: see catalogue or data sheet.
