KSB Omega User Manual

The forces and moments indicated refer to external, simultaneous loads in 3
dimensions (F
x
= F
y
= F
z
and M
x
= M
y
= M
z
). They only apply if the pump set has been
properly installed in accordance with the installation/operating manual. The forces
and moments in any direction must not exceed the values given in the table. The
data on forces and moments apply to static piping loads only. If the limits are
exceeded, the values must be checked and verified. The piping must be connected
without transmitting any stresses or strains. The pump must not be used as support
for the piping. The pump is not an anchorage point for the piping. The piping must
be fastened without transmitting any forces, vibrations or pipe weights to the pump.
Observe the limits for forces and moments at the suction and discharge nozzle. The
pump must not be connected with unbraced expansion joints.
