Some reasons why pumps may end up requiring repairs are due to excessive vibrations. Normally, “Properly installed pumps average 0.71 in/sec overall vibration and have 60 months life.” 1 There are many factors which can cause a pump to vibrate, such as those relating to parts. The parts may be rubbing, old, worn-out or damaged, a base for the pump being too small. Other potential causes for excessive vibration can be pump cavitation 2 , imbalance, vibration from other nearby
