Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbo machinery and used to transport fluid by conversion of rotational kinetic energy to hydrodynamic energy. This project investigates the study of complex internal flows in centrifugal pump impellers with the aid of computational fluid dynamics software thus facilitating the design of pumps. Here three different types of pump impellers had been taken. The pump specifications considered for investigation are discharge and speed. These specifications have been varied to perform a comparative study of these pump impellers. The impeller was modelled in CATIA and the blade to blade plane of the impellers was taken for the detailed study purpose because the flow occurs through this passage only. The blade to blade plane is modelled in CATIA software and the flow analysis is carried out using CFD software. Thus the valid results regarding the velocity distribution and pressure distributions were predicated and the performance of those pumps had been compared from the computational results.
