I are the sums of the absolute values of the permissible forces and
moments acting on the nozzles.
The data on forces and moments apply to static piping loads only. If the limits are
exceeded, they must be checked and verified.
If a computerised strength analysis is required, please contact KSB.
The values are only applicable if the pump is bolted to a rigid and level foundation.
