Centrifugal pumps are commonly used for pumping sewage, petrochemicals etc. The structure of a hydraulic machine, as a centrifugal pump, has evolved primarily to fulfill the requirements of fluid flow. This book compiles various case studies which take into consideration the strong collaboration between the pump and the pumping installation, and the need to manage the process. It also discusses the necessity to operate best efficiency in order to save energy, the condition to advance the operation against cavitation and other significant topics. The book will be beneficial for readers interested in gathering information about centrifugal pumps.
