Rotodynamic pump design

This book provides a brief but thorough account of the basic principles of good pump design. The first three chapters of the book present the basic hydraulic equations, including cavitation, and discuss the principles that underlie the correct performance of the impeller and casing of centrifugal pumps and the blading of axial machines. The fourth chapter outlines analytical methods for flow calculations, including special techniques used in computer aided design. The following two chapters work through two examples: the first the preliminary design of the impeller and casing of a simple volute type centrifugal pump; the second outlines alternative approaches to designing an axial flow pump impeller. The important topics of shafts, bearings, seals and drives are discussed in a separate chapter, followed by a short chapter on the problems associated with designing pumps for use with difficult liquids. The final chapter introduces the industrial codes and practices that must also be taken into account in finalising any pump design. This text will be of interest to graduate students, research and professional designers in mechanical, aeronautical, chemical and civil engineering.
