Preface
Life is linked to liquid transport, and so are vital segments of economy. Pumping devices - be it the human heart, a boiler feeder or the cooling water pump of a motorcar - are always part of a more or less complex system where pump failure can lead to severe consequences. To select, operate or design a pump, some understanding of the system is helpful, if not essential. Depending on the application, a centrifugal pump can be a simple device which could be built in a garage with a minimum of know-how - or a high-tech machine requiring advanced skills, sophisticated engineering and extensive testing. When attempting to describe the state of the art in hydraulic engineering of centrifugal pumps, the focus is necessarily on the high-tech side rather than on less-demanding services even though these make up the majority of pump applications. Centrifugal pump technology involves a broad spectrum of flow phenomena which have a profound impact on design and operation through the achieved efficiency, the stability of the head-capacity characteristic, vibration, noise, component failure due to fatigue, as well as material damage caused by cavitation, hydro-abrasive wear or erosion corrosion. Operation and life cycle costs of pumping equipment depend to a large extent
