This new edition of the Handbook takes full account of the recent progress that has been made in pump construction and technology.  The aim of this book is to provide an overview of the current state of the art in pump construction. It is intended for planners and operating companies alike. To make the content accessible we have included the most important information but in some instances limited the degree of detail provided to that we believe is most commonly required. Problem aspects such as cavitation, erosion, selection of materials, rotor vibration behavior, forces acting on pumps, operating performance in various systems, drives, acceptance testing and many more are dealt with in detail.
