This book shows how condition monitoring can be applied to detect internal degradation in pumps so that appropriate maintenance can be decided upon based on actual condition rather than arbitrary time scales.
The book focuses on the main condition monitoring techniques particularly relevant to pumps (vibration analysis, performance analysis). The philosophy of condition monitoring is briefly summarised and field examples show how condition monitoring is applied to detect internal degration in pumps.

* The first book devoted to condition monitoring and predictive maintenance in pumps.
* Explains how to minimise energy costs, limit overhauls and reduce maintenance expenditure.
* Includes material not found anywhere else.
