chapter  3
Hydraulic Pumps and Intensifiers
Pages 27

For pressurized hydraulic power and control systems, positive-displacement-type pumps (piston, gear, and vane, for example) are chosen most often (Figs. 3.1 to 3.18). Centrifugal and other dynamic types usually are reserved for fluid handling rather than pressure or power, so only a brief section on "dynamic" types is included at the end of the chapter.
