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, seaPumping machineryHydraulic controlPumping machinery.Hydraulic control.621.6/9TEC009000bisacshBloch Heinz P.1933-621787MiAaPQMiAaPQMiAaPQBOOK9910139454003321Pump wisdom2168419UNINA
