Vibrations basically are the displacement of a mass back and forth from its static position. In every pump, dynamic forces of mechanical and hydraulic origin are present and a certain vibration and noise is therefore inevitable. To ensure the safety of the pump and associated plant components, the vibration and noise must be kept within certain limits. The objective of the paper is to identify the fundamental natural frequency of peristaltic pump. Effect of vibration on performance of
