TROUBLESHOOTING CENTRIFUGAL PUMPS AND THEIR 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 can be diagnosed and rectified using a combination of knowledge and experience, the latter coming over time. This book, written by a very experienced engineer, guides the reader through diagnostic pathways leading to logical explanations for the malfunctions and their correction.
