This CEN Technical Report provides information for the calculation of maximum permissible forces and moments
allowed on the flanges of various types of horizontal and vertical shaft rotodynamic pumps, caused by the reaction to
pipework that is rigidly connected to the installation. This document does not take into account the effect of any elastic
or deformable linkages, such as bellows, elastic joints, self butting sliding joints, etc.
This CEN Technical Report is not applicable to multistage monobloc pumps, whose outlets are remote from the
installation plane, or to horizontal shaft pumps mounted vertically for installation reasons, such as, fixing to a vertical
wall.
