AB  - Erosion in slurry pumps presents a persistent challenge in industrial applications. This study examines the erosion of the static components of a 150ZJ-C42 centrifugal slurry pump, currently in operation at a beneficiation plant, under varying particle conditions. Utilizing high-precision three-dimensional reverse engineering, the pump’s flow passage geometry was reconstructed to facilitate detailed erosion analysis. Focusing on the front and rear baffles of the pump chamber, as well as the volute, erosion patterns were analyzed for different particle volume concentrations and sizes. The results reveal that the highest erosion damage consistently occurs near the volute tongue, with wear being most severe in regions adjacent to the partition plate near the rear cover. Erosion damage intensity in this area correlates positively with particle diameter. Notably, the average erosion rate in the volute surpasses that of the front and rear chamber liners, reaching a value as high as 6.03 × 10<sup>−7</sup> kg·m<sup>−2</sup>·s<sup>−1</sup> at a particle concentration of 9% and diameter of 0.1 mm, adversely impacting pump stability. For the pump chamber baffles, increased erosion is observed at a particle diameter of 0.05 mm under constant volume concentration conditions, while higher particle concentrations exacerbate localized erosion.
