Pump Wisdom: Problem Solving for
Operators and Specialists. By Heinz P.

espite their ubiquity in the chemical process
industries (CPI), process pumps fail catastrophically
each year in large numbers. The author, a
world-recognized expert on pumps and other process
equipment, has written this book to explain some elusive
failure causes and to provide permanent remedial actions
to avoid or minimize such failures. In the preface to this
excellent book, the author states that he intended to write
a book that would squeeze material to enhance both pump
safety and reliability into 200 or so pages. To date, some of
this material has been too widely dispersed to be readily
accessible, and some important material has never been
published before. In my opinion, the author has achieved
his goals. The book provides valuable knowledge based
on the author's years of experience in the petroleum and
chemical industries on techniques for stabilizing centrifugal
pump performance and maximizing pump efficiency.

Its concise format allows readers to get to the heart of
potential problems and helps them devise strategies to
prevent costly failures. This book will be useful not only to
pump operators and designers, but also to process-design
and project engineers, who have to select and install centrifugal
pumps, as well as to maintenance engineers, who
have to see that they run safely and efficiently.
Topics covered in the book's early chapters include fundamental
principles of centrifugal process pumps, including
pump performance, operation at zero flow, impellers
and rotors, as well as centrifugal pump types and pump
mechanical response to flow changes. Early on, the book
also offers a succinct review of pump selection and industry
standards, including ANSI and ISO versus API pumps,
and includes a wealth of practical information designed to
help minimize problems. Among the topics found are piping
design and selection of stationary seals and gaskets.
Subsequent chapters describe practices to ensure reliable
operation of pump bearings, lubricant application and cooling
considerations in good detail. Topics considered include
lubricant viscosities, bearing housing protection and cost
justification. There is also a good overview of mechanical
sealing options for long life.
Later chapters present pump startup, surveillance and
shutdown procedures, as well as impeller modifications
