7. Fluid transfer and gas compression applications

7.1 Centrifugal pumps

Almost 90% of pumps used in industry are centrifugal or axial pumps. These are turbomachines that transmit the mechanical energy available on the shaft to the fluid flowing through them, transforming it into potential energy (height or pressure). The forces exerted on the fluid lead to an increase in kinetic energy and static pressure. The very wide power range of these pumps, and the very wide variety of uses they can be put to, explain why they come in so many variants....
