The problems presented in this paper concern the operating parameters, efficiency and flow effects experienced in the impellers of the centrifugal compressor DA 200 manufactured at HCP Poznań S.A. The centrifugal compressor DA 200 operates equipped optionally with three different impellers, and in case of two propellers the different geometries of splitter blades have been used. Based on the performed experimental research work the obtained results for each of three impellers are presented in a form of the compression process efficiency. Moreover, the distributions of pressure are subject to the relevant analysis with respect to the impeller exit width. The distributions of pressure obtained in the experiments are compared with the results of the numerical analysis calculations carried out with use of the REFlux code.
