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. 606 $aCentrifugal pumps 615 0$aCentrifugal pumps. 676 $a621.6/7 700 $aBachus$b Larry$0627357 701 $aCustodio$b Angel Antonio$f1947-$0738986 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910784016103321 996 $aKnow and understand centrifugal pumps$93797130 997 $aUNINA
