MAXIMUM MOMENTS APPLIED TO A PUMP ON A FULLY BOLTED AND GROUTED BASEPLATE. LOADS ARE TO BE
APPLIED ONLY THROUGH THE SUCTION AND DISCHARGE FLANGES.
Maximum allowable forces and moments
calculated from these force equations or the
tabulated moment tables are those resulting in
a maximum of .010 inch movement of the
shaft measured at the shaft coupling when the
pump is mounted on its baseplate and that
baseplate is fully bolted to a properly
designed foundation and is fully grouted in
place. For a full discussion see API Standard
610, 5th Edition.
