The slip of pump feet on the baseplate caused by piping loads was investigated. The test pump was axially-split, single-stage, double-suction volute type with foot support. The static coefficient of friction between the pump foot and baseplate ranged between 0.15 and 0.35, The effects of dowel pins and jack screws against the slip were also investigated. Furthermore, shaft displacements due to the deformation of pump casing and baseplate were measured. In the case of test pumps, the proportion of the shaft displacement due to casing deformation to that of pump assembly was 50% and more in most load conditions. Then, the rigidity of not only the baseplate but also the pump casing must be increased when large piping loads over API loads are specified.
