520 Pumps are commonly encountered in industry and are
essential to the smooth running of many industrial
complexes. Mechanical engineers entering industry often
have little practical experience of pumps and their
problems, and need to build up an understanding of the
design, operation and appropriate use of pumps, plus how
to diagnose faults and put them right. This book tackles
all these aspects in a readable manner, drawing on the
authors' long experience of lecturing and writing on
centrifugal pumps for industrial audiences
