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
