A centrifugal pump is a rot dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are ordinarily used to move liquids through a piping system. The fluid enters the pump impeller on or almost the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber, from where it exits into the downstream piping system. Its purpose is to convert the energy of a main-rate} mover (a motor or turbine) first into rate or kinetic energy then into pressure energy of a fluid that is being pumped. Centrifugal pumps are used for big discharge through smaller heads. centrifugal pumps convert mechanical energy from a motor to the energy of a moving fluid, a number of the energy goes into mechanical energy of fluid motion, and a few into potential energy, represented by fluid pressure or by lifting the fluid against gravity to a higher level. In this project analysis on MS and SS pump impeller is done in order to optimize the strength of the centrifugal pump. This gives the static and Modal analysis of MS and SS Pump Impeller to check the strength of Pump and vibrations produced by the pump. On doing the static and modal analysis of pump impeller it is clear that the maximum deflection induced in metallic pump fan, which is in safe limits. The maximum induced stress for the same material which is less than the allowable stress i.e. working stress by considering the factor of safety. Hence the design is safe based on strength. If we compare the corresponding deformation of the material SS on results MS material, SS having minimum deformation, therefore, there are fewer chances of failure of the pump fan as compare to MS materials. The strength of the pump gets increased because of the SS material.
