Preface

This book is a completely revised and updated version of "Pump Selection and Application. " The wide acceptance of this work throughout the world in several languages led the authors to broaden its coverage. Thus, the present volume has been titled "Pump Application Engineering" to reflect the broad scope and depth of coverage.

Since "Pump Selection and Application" was published in 1957, many spectacular technological advances have caught the public eye—space exploration, moon landings, heart transplants, nuclear power, to name but a few. But, while it has not been so obvious to everyone, all of these advances have been dependent upon a rapidly developing pump technology. This really is not a surprising or unjustified statement to make when one remembers that, next to the electric motor, pumps are the most widely used machines in the world. There is hardly a single piece of major equipment that does not in some way depend upon pumps for its successful operation.

In "Pump Application Engineering" we have updated many of those areas of pump technology that have supported and contributed to the numerous advances of the 1960s. At the same time, however, we have retained the detailed information on correct pump selection and application that contributed so much to the value of "Pump Selection and Application. " This combination provides the engineer in industry with the complete and up-to-date information he needs to select correctly and apply the pumping equipment required to perform a specific job.

Some recent technological advances have affected all types of pumping equipment. These advances include improved materials, better pump design, and superior quality-assurance techniques. Such advances permit successful pumping equipment application in increas-ingly severe services. These advances also prolong pump life and increase operating" reliability.

Other recent advances pertain more specifically to certain pump types or services. Included are such items as increased equipment standardization, the wide application of so-called twin volutes, improved mechanical-seal designs, order-of-magnitude size increases, and the general pushing back of temperature limitations at both the low and high ends of the scale.

As a good example, take the pumping equipment needs of the nuclear-power industry. Here we have a whole new industry that has developed on a commercial basis since "Pump Selection and Application" was published in 1957. While pumps for nuclear power are numerous and diverse, probably the most severe and exacting service is for the primary circulators. In pressurized-water-reactor systems, these giant pumps handle capacities in the range of 100,000 gpm. Although developed heads are quite moderate, suction heads are high and the water pumped in extremely hot. Leakage limitations—or actual prohibition in some designs—require sophisticated sealing arrangements whose reliability must be of the highest order. Nuclear-power safety requirements are extremely stringent; this means that all pumps in the system are subjected to repeated design and quality-assurance checks. Reliability and safety are even further enhanced by built-in equipment redundancy and complex monitoring and control systems.

In gathering data and information for "Pump Application Engineering, " the authors are indeed grateful to the many pump manufacturers who so generously supplied up-to-date illustrations and freely offered their informed suggestions for improvements in the text. As was the case when "Pump Selection and Application" was published, the Hydraulic Institute has again permitted wide use of its latest "Standards" material—an authoritative consensus of the vast store of pump application data developed over the years by the Institute's member companies. In addition, the Bureau of Labor Statistics of the Linked States Department of Labor provided invaluable information for updating economic evaluation problems.

The authors hope that this new book will assist engineers everywhere who must select and apply pumps of all types. Any suggestions for the improvement of future editions will be gladly welcomed.
