This practical reference describes the occurrence of cavitation in a centrifugal pump, and how unacceptable cavitation can be avoided. It explains cavitation problems such as hydraulic performance loss, hydrodynamically or thermodynamically induced surging, and cavitation erosion. General guidelines for acceptable operation conditions, such as, net positive suction head (NPSH) margins and minimum flowrates, are presented along with evidence and logic for these proposed guidelines.

This book gives an unparalleled, up-to-date, in-depth treatment of all kinds of flow phenomena encountered in centrifugal pumps including the complex interactions of fluid flow with vibrations and wear of materials. The scope includes all aspects of hydraulic design, 3D-flow phenomena and partload operation, cavitation, numerical flow calculations, hydraulic forces, pressure pulsations, noise, pump vibrations (notably bearing housing vibration diagnostics and remedies), pipe vibrations, pump characteristics and pump operation, design of intake structures, the effects of highly viscous flows, pumping of gas-liquid mixtures, hydraulic transport of solids, fatigue damage to impellers or diffusers, material selection under the aspects of fatigue, corrosion, erosion-corrosion or hydro-abrasive wear, pump selection, and hydraulic quality criteria. As a novelty, the 3rd ed. brings a fully analytical design method for radial impellers, which eliminates the arbitrary choices inherent to former design procedures. The discussions of vibrations, noise, unsteady flow phenomena, stability, hydraulic excitation forces and cavitation have been significantly enhanced. To ease the use of the information, the methods and procedures for the various calculations and failure diagnostics discussed in the text are gathered in about 150 pages of tables which may be considered as almost unique in the open literature. The text focuses on practical application in the industry and is free of mathematical or theoretical ballast. In order to find viable solutions in practice, the physical mechanisms involved should be thoroughly understood. The book is focused on fostering this understanding which will benefit the pump engineer in industry as well as academia and students.

This last, the education of pump users, is precisely what this book was intended to do. To what extent we must have achieved our purpose, our readers must decide. My good friend and associate, J. T. (Terry) McGuire, and I have been working very closely together for a long time. Our view of engineering problems and of their solutions coincide to an astonishing degree. When I was asked to prepare a second edition of my book Centrifugal Pumps, it was logical that I turned to Terry and suggested that he be my coauthor on this project. He agreed to do so, and his cooperation has been most valuable, both in improving the resultant work and in easing my burden. It would be presumptuous on my part to pretend that nothing has changed in the technology of centrifugal pumps during the 30 years since I prepared the manuscript for the first edition of this book. Let me, then, speak of some of these changes.

How to Select the Right Centrifugal Pump

How to Select the Right Centrifugal Pump

What good is a low cost pump if it is inefficient or if is costly to maintain? The selection methodology offered in this book focuses mainly on hydraulic design considerations, but it also touches on mechanical design details.

Choosing a centrifugal pump from the countless options available can be daunting, but someone has to make the decision. Many factors -such as the required flow, differential pressure, suction conditions, etc.- must be weighed against the capital costs and cost of energy for the pumps considered. To determine the right pump, you must consider the overall cost of ownership, which includes capital cost, operating costs, and maintenance cost. What good is a low cost pump if it is inefficient or if is costly to maintain? The selection methodology offered in this book focuses mainly on hydraulic design considerations, but it also touches on mechanical design details. Analyzing basic pump hydraulic parameters allows you to quickly determine if a centrifugal pump makes sense for your particular application. If you do decide a centrifugal pump will work for your application, then you need to be able to evaluate the various bids returned by pump manufacturers. A complete chapter is devoted to tabulating quotes from pump manufacturers in order to properly evaluate their bids and select the best overall option.

Originally puublished in 1915. PREFACE: The extensive use and increasing popularity of centrifugal pumping machinery make it necessary for many to become familiar with this subject in all its phases. In this book an effort has been made to cover the following ground To illustrate and explain all the essential features of construction of modern centrifugal pumps, to present a clear and intelligible theory which shall be entirely general in its nature, to explain by this theory the pump characteristics and connect the theory with the actual facts, to present a thorough discussion of the factors affecting efficiency, to considerthe characteristics of varioustypes ofpumps and their suitability for different services, to compare centrifu- gal with displacement pumps, and to present various general laws and factors leading to a better appreciation of the field of service of such pumps and a better means of selecting the proper combinations. While this is not primarily a book on design, it is believed that a thorough study of the foregoing will be of value to prospective designers, and in addition the methods of design of centrifugal pumps are outlined. The material in this book is based upon a study of the performances of 123 turbine and 51 volute centrifugal pumps made by 17 and 12 different companies respectively. The field covered by them ranged from 1 to 11 stages, heads from 7 to 1843 ft., capacities from 108 to 132,000 gal. per minute, speeds from 62 to 20,000 r.p.m., and efficiencies from 30 to 87 per cent. A considerable portion of the work is also founded upon the anal- ysis of tests made by the author upon a volute pump and a turbine pump for both of which all information regarding dimensions and other quantities was obtainable. With the turbine pump an extensive and accurate series of tests was made at various speeds from 700 to 2,000 r.p.m. Both of these pumps were regular commercial pumps of good design, not freak pumps built for experimental purposes only. The author has drawn upon trade catalogues and several books and papers for much of his material, due credit for which is given in the text, but it is believed that a very great deal of the following treatise will be found to be new. The common usage regarding terms employed has been followed as far as possible, but in cases where there were no precedents or where the usage was illogical and confusing, new terms have been created. It is hoped that eventually some of these things may become standardized. The book has been so written as to serve the needs of the practising engineer who wishes to obtain a grasp of this subject. By the insertion of problems and questions it is believed that it will be found equally well adapted for use as a text. Contents include: PREFACE v CHAPTER I INTRODUCTION 1 Definition Classification Reaction turbine vs. turbine pump Historical development Conditions of use Pump size Rated head and discharge...
