Polymeric pumps represent a technological solution when used for aggressive chemical liquids and abrasives. The present work investigates the effect of pressure load on the elastoplastic behavior of an impeller made of polymer. The main objective is a comparison between impellers with different parameters such as number of blades, external diameter and width of the blade. The computations are made using three-dimensional finite element under ABAQUS code. The behavior of the polymeric impeller is investigated under mechanical loads taking into consideration the mechanical characteristics of the material. This tark is conditioned by a deep understanding of the elastoplastic behavior of the polymeric impeller. The results obtained show the parameters under consideration have a sensitive effects on the behavior of the impeller concerning the displacements and von misees stresses. The present work as well as the other research mentioned in this paper aim for a better design and optimization to meet a good performance of centrifugal pump .
