Slurry erosion with sand particles is a serious problem for pumps operating at the Yellow River pumping station. Therefore, a technique to predict erosion volume loss is required for selecting erosion resistant material and determining specification of the maintenance period. This paper reports a method to predict the volume loss of SCS6 specimen using slurry jet apparatus. An equation for prediction is derived from combining an analysis of sand particle behavior in the slurry jet apparatus with measurement of surface profile on specimens obtained by slurry jet test by silica sand of approximate 60μm in mean diameter. There is a critical value for kinetic energy of particle above which erosion occurs being about 1.0x10-6N•m for SCS6. It was found that the loss was a maximum at an impact angle of about 40 degrees. The equation can predict the wear depth on the slurry jet test with the Yellow River sand of approximate 30μm in mean diameter.
