By
  • UNKNOWN AUTHOR

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.
