Abstract: Base Frame are the traditional and most common means for reducing weight of pump. The factor of safety of existing base frame is more than the required. In this project work, after optimizing weight of base frame of multistage centrifugal pump the factor of safety reduces and it becomes as per required. For weight reduction we considered the forces and moments acting on the suction and discharge nozzle of the pump. Shaft deflection analysis is carried out by using ANSYS software. Also the shaft deflection of pump is checked after optimization which is within API 610 standard.
