Clearly written by an ace consultant, this manual for operators and specialists in the petroleum industry gives readers a concise overview of the mechanics of various pumps and reviews the specifications to be considered before a pump is purchased and installed. The straight-forward text explains pump hydraulics without need of involved mathematics and provides expert advice on installing centrifugal pumps in process plants. The book also emphasizes the mechanical aspects of pumps as it delves into misunderstandings and oversights on bearings, sea 606 $aPumping machinery 606 $aHydraulic control 615 0$aPumping machinery. 615 0$aHydraulic control. 676 $a621.6/9 686 $aTEC009000$2bisacsh 700 $aBloch$b Heinz P.$f1933-$0621787 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910139454003321 996 $aPump wisdom$92168419 997 $aUNINA
