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.

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
When using the pump in air conditioning or cooling systems:
• The condensate that forms in the lantern can be drained specifically via an existing
drilled hole. A drain pipe can also be connected to this opening and a small amount of
escaping liquid can be drained off.
• The motors are equipped with condensation water holes which are closed with a rubber
plug at the factory. The rubber plug is used to guarantee that protection class IP55 is
fulfilled.
• Installation position:
All installation positions except for "motor facing down" are allowed.
• The air vent valve (Fig. I/II, Item 1.31) must always point upward.
