The outlet velocity characteristics of an impeller is one factor that determines the hydraulic performance as well as the wear in the casing of a slurry pump. In this study the results of detailed flow field measurements of three similar sized impellers with different design of the meridional section are reported. Two impellers are slurry pump impellers of two different manufacturers, the third one is an impeller for pure water handling designed with respect of high efficiency. The measuring results are then applied in a quasi three-dimensional computer code to determine casing wear. This shows the role of the impeller design on wear. The results also show, which component of the impeller outlet velocity is the important one. In a first step pump operation at BEPQ is considered.
