| The Centrifugal Pump book is intended primarily for internal use by specialists involved in the development and manufacturing of pump components. Furthermore, the book is aimed for our future colleagues, university and engineering students, who will be able to use it as a reference and source of inspiration while studying. In the first chapter, we describe the centrifugal pump theory and its hydraulic components, as well as a list of Grundfos' pump models. The second chapter explains how to read and understand pump performance curves for head, power, efficiency, and NPSH. Chapter 3 describes how to change the pump's performance while it is in operation in a system. Chapter 4 introduces the theoretical underpinning for energy conversion in a centrifugal pump and describes how affinity principles are used to scale pump impeller performance. In Chapter 5, we discuss the many types of losses that occur in pumps and how they effect flow, head, and power consumption. The book's last chapter, Chapter 6, walks us through the many test types that Grundfos conducts on both assembled pumps and pump components to guarantee that the pump performs as expected. |
