PREFACE

TO THE THIRD EDITION

It is difficult to follow in the footsteps of Igor J. Karassik, whose vision and leadership played a major role in the concept of a handbook on pumps that is broad enough to encom pass all aspects of the subject—from the theory of operation through design and application to the multitude of tasks for which pumps of all types and sizes are employed. That vision was realized in the first edition of the Pump Handbook, which appeared a quarter century ago, with the capable and dedicated co-authorship of William C. Krutzsch, WarrenH. Fraser, and Joseph P. Messina. Acceptance of this work globally soon led these distin guished pump engineers to assemble a second edition that not only contained updatedguished pump engineers to assemble a second edition that not only contained updated guished pump engineers to assemble a second edition that not only contained updated material but also presented all numerical quantities in terms of the SI system of units in addition to the commonly used United States customary system of units.Worldwide developments in pump theory, design and applications have continued to emerge, and these have begun to affect the outlook of pump engineers and users to such an extent that a third edition has become overdue. Pumps have continued to grow in size,speed, and energy level, revealing new problems that are being addressed by innovative materials and mechanical and hydraulic design approaches. Environmental pressures have increased, and these can and are being responded to by the creative attention of pump engineers and users. After all, the engineer is trained to solve problems, employing techniques that reflect knowledge of physical phenomena in the world around us. All of this has led the current authors to respond by adding new sections and by revising most of the others as would be appropriate in addressing these developments. Specifically the following changes should be noted.Centrifugal pump theory, in the rewritten Section 2.1, proceeds from the basic govern ing fluid mechanics to the rationale that underlies the fundamental geometry and performance of these machines—while maintaining the concrete illustrations of design examples. A new subsection on high-energy pumps is included.An update has been made to Section 2.2.1 on major components of centrifugal pumps.Section 2.3.1 on centrifugal pump general performance characteristics has been updated.The emerging technology of magnetic bearings is presented in the new Section 2.2.6.Section 2.2.7, is a new treatment of sealless centrifugal pumps that includes both the canned-motor and magnetically-coupled types.Chapter 3 on displacement pumps has been reorganized and includes updates of the

sections on both reciprocating and rotary positive displacement pumps.A new Section 4.1 on jet pump theory begins the chapter on jet pumps and deals with liquids and gases for the motive and secondary flows as well as the basics of design optimization Chapter 5 on materials of construction, including the Sections 5.1 and 5.2 on metallicand nonmetallic materials respectively, has been completely rewritten and updated.Chapter 6 on pump drivers has been updated, Section 6.1.1 on electric motors and Section 6.2.2 on adjustable-speed electric drives having been substantially rewritten.In Chapter 9 on pump services, most of the applications sections have been updated,including those for fire pumps (Section 9.4) and pumps for steam power plants (9.5), pulpand paper (9.8), mining (9.10), metering (9.15), pumped storage (9.13), and nuclear services (9.14).Section 9.11 on marine applications has been rewritten.Sections 9.16.1 on hydraulic transport of solids and 9.16.2 on centrifugal slurry pumps are completely new and include several examples.

A new section on aerospace pumps has been added, which includes Sections 9.19.1 on aircraft fuel pumps and 9.19.2 on liquid rocket propellant pumps.Section 9.20 on handling hazardous liquids is new.Chapters 10 on intakes and suction piping, 11 on selecting and purchasing pumps and 12 on installation, operation, and maintenance have been updated.We recognize that further developments are going on apace and that more could have been done. Computational fluid dynamics (CFD) and finite-element structural and rotor dynamic analysis techniques, as well as the revolution in information management and utilization, already promise to profoundly transform pump design, application, and operational practice—and indeed all other areas of engineering endeavor. Nevertheless, we offer this third edition of the Pump Handbook as a practical tool for the present day. In this sense, we hope that it will fulfill the vision of the authors of prior editions while at the same time serving as a stepping stone to the future world of pumping.
