When a machine fails or breaks down, the consequences can range from annoyance to financial disaster, or personal injury and possible lose of life. For this reason, the early detection, identification and correction of machinery problems is paramount to anyone involved in the maintenance of industrial machinery to insure continued, safe and productive operation..Of course, it’s natural for machines to vibrate. Even machines in the best of operating condition will have some vibration because of small, minor defects. Therefore, each machine will have a level of vibration that may be regarded as normal or inherent. However, when machinery vibration increases or becomes excessive, some mechanical trouble is usually the reason. Vibration does not increase or become excessive for no reason at all. Something causes it - unbalance, misalignment, worn gears or bearings, looseness, etc. This paper focuses on the machinery (Centrifugal pump) vibration due to unbalance and the technological effect on its performance. This study is done to evaluate the performance of the centrifugal pump on different unbalance masses. Some times these studies are quite helpful in order to equip better design of pump so that there should be minimum effect on its performance due to unbalance. Keywords: vibration, eccen
