Pump Characteristics and Applications 2nd Edition By Michael Volk


Preface to the Second Edition

Thankfully, the laws of physics have not changed since the
first edition of this book was written in 1996. Therefore, virtually
everything about pump selection, sizing, system analysis,
and other aspects of pump hydraulics remains
unchanged from the first edition. There have, however, been
a number of innovations in the world of pumps, which are
introduced in this second edition. This edition also expands
the material on many components of typical pump installations
that were only briefly covered in the first edition, if at
all. Some of the most important new or expanded topics covered
in this second edition include:
pumps are introduced, while the information
on other types of P.D. pumps has been
•include NPSH analysis for closed systems, expansion
of the discussion on NPSH margin, and system head
curve development for existing systems and for parallel
pumping systems.
•eternity, and so the entire section of this chapter
covering software used to design and analyze pump
piping systems has been completely rewritten. A new
CD is included with the second edition of the book,
demonstrating one such software tool, including solving
some of the problems covered in the book.

important and relevant topics: pump couplings and
electric motors. Additionally, several types of centrifugal
pumps that were not included in the first edition
are covered in this chapter.

of variable-frequency drives. Second, this
chapter includes a section covering pump life-cycle
cost, an innovative approach to the study of the cost
of pumping equipment that looks way beyond the
capital cost of the pump.

on elastomers commonly used in pumps for
sealing components.

pumps, and a much more detailed discussion of vibration,
