Abstract: It is very difficult and complex to analyze the hydraulic performance and characteristics of a centrifugal pump. Additionally, pump operation hugely depends on a large number of interdependent variables. This work aims to study the performance analysis of a centrifugal radial flow pump designed to deliver 0.0074 m3 /s of water with a head of 30 m at a speed of 2870 rpm using ANSYS CFX (ver.14.0). The pump unit has been modeled using PTC Creo (ver. 2.0). In order to analyze the flow, Computation fluid dynamics (CFD) has been used. The performance of the pump was first determined using the existing number of the blades and then, the number of blades has been varied to analyze the pump’s performance. The results show that for the optimized value, pump efficiency increased by 2.23%
