Abstract -The impeller of a centrifugal pump plays an important role in converting the input driver energy into kinetic energy. The impeller is a complex structure and moreover the conventional trial and error method is cost consuming to experiment with. CFD analysis is a solution to this problem. This paper presents the numerical investigation of the effects that the pertinent design parameters, including the blade number, the inlet blade angle, trimmed impeller profile, and the impeller diameter, have on the steady state liquid flow in a three-dimensional centrifugal pump. Initially the impeller model is geometrically constructed based on certain performance modified parameters. The model is then meshed and CFD analysis was carried out. The inner flow fields, pressure and velocity distribution were predicted.  Results obtained from the analysis were then compared with the actual results and inferences were made.
