Fans and axial/radial compressors
A characteristic of fans is the pressure ratio, which indicates the ratio of the absolute final pressure to the absolute intake pressure. Fans are different from compressors because of their low pressure ratio of max. 2,5.

Centrifugal pumps
In centrifugal pumps the energy is transferred hydrodynamically.In the hydrodynamic transfer of energy the fluid is accelerated by the impeller of the centrifugal pump. Therefore, the impeller of the centrifugal pump has to move with high velocity and thus a high rotational speed.

Axial-flow pumps
Axial-flow pumps are also known as propeller pumps. Axial-flow pumps come with fixed blades and with variable blades. The flow passes through the impeller in axial direction. In axial-flow pumps, the pressure is not built up by the effect of centrifugal force but, like the aerodynamic principle, by the propeller blade.
