Abstract：The technology development of net positive suction(NPSH) performance indexes about single-stage and single-suction rinsing centrifugal pumps is evaluated.More than 3 000 sample values of performance indexes about vertical and horizontal pumps are collected and compared,and these statistic and neat data are analyzed in detail.Based on these data,it is pointed out that the sample values are inconsistent with measuring ones,performance indexes under low rotating speed are better,and efficiency performance indexes are lower for vertical pumps.centrifugal pump;single-stage and single-suction;efficiency;NPSH
