The list of pump failure conditions mentioned above is neither exhaustive nor are the
conditions mutually exclusive. Often the root causes of failure are the same but the
symptoms are different. A little care when first symptoms of a problem appear can save the
pumps from permanent failures. Thus the most important task in such situations is to find
out whether the pump has failed mechanically or if there is some process deficiency, or
both. Many times when the pumps are sent to the workshop, the maintenance people do not
find anything wrong on disassembling it. Thus the decision to pull a pump out of service for
maintenance / repair should be made after a detailed analysis of the symptoms and root
causes of the pump failure. Also, in case of any mechanical failure or physical damage of
pump internals, the operating engineer should be able to relate the failure to the process
unit’s operating problems
