Abstract In order to make suggestions for engineers and researchers who work in pump industry to calculate NPSH, the causation of cavitation occurred in a slurry pump theoretically is analyzed.The relationship between NPSH and inlet geometry parameters of impeller is analyzed .The cavitation characteristic between the slurry pump and normal pump is compared.The empirical formula that used to calculate NPSH is deduced base on test datas and the example for calculating NPSH is validated.
