In the present scenario, Energy demand is increasing day by day. To meet that demand, the production or extraction of crude oil, natural gas and other energy resources is done with the help of various pumps. Pumps are the second largest used machinery in world and plays a vital role. In this paper, we have done analysis on centrifugal pump categorised as overhung pump (OH2). It is commonly known that vibration problems on centrifugal pumps can result from multitude of possible parameters which are not easily identified. Due to deviation of pumps from best efficiency point (BEP), their service life is reduced and vibration can be a root cause of this problem. The unwanted vibration especially in overhung pump effect the performance of centrifugal pump and its mechanical characteristics. In the present paper, we had done an analysis by changing the design of pump feet. During mathematical and experimental analysis (using FFT analyser) it was observed that frequency of vibration is reduced to certain amount which result in enhancing service life.
