Troubleshooting Centrifugal Pumps and Their Systems
Troubleshooting Centrifugal Pumps and Their Systems, Second Edition, begins by discussing pump characteristics that can be reconfigured to suit changing conditions. Next, it provides guidance on when to withdraw a pump from service for repair and how it should be subsequently treated. It is an ideal resource for those who feel ill-equipped to analyse unsatisfactory pump system behaviour, and is also a great reference for pump engineers, pump hydraulic designers, and graduate students who need systemic knowledge on centrifugal pumps and their systems.
- Presents the basic mechanisms of abrasive wear in centrifugal pumps, including different wear patterns and their causes
- Discusses performance improvements to help readers meet the new requirements of a pumping system
- Describes repair and life improvement techniques
- Includes real-world examples of troubleshooting in centrifugal pumps and systems

Pumps are fine until they malfunction or break down. When that happens, the first priority is to get the pump functioning again and to keep ”down time” to a minimum. Many problems diagnosed and rectified using a combination of knowledge and experience, the latter coming over time. This book, written by an experienced engineer, guides the reader through diagnostic pathways leading to logical explanations for the malfunctions and their correction.
Most of the pumping systems covered by this book would have begun with an assumption that the liquid being handled is almost free from suspended solids. Except where this is unavoidable, most manufacturers will encourage the user to take steps to make sure this condition is met.
