The paper considers centrifugal pumps 8 Gr-8, component of the hydro-transport of the ore-dressing operation line, which pumps abrasive hydro-mixtures (pulp). The pumps working conditions are described and the results from wear measurement of the impeller, wear plate and housing are shown for different operation times. The wear patterns of the examined parts are determined and the causes for their intensive wear and the methods of its reduction are identified.
