Quick Summary

An axial-flow pump is a type of pump where the fluid or gas flows parallel to the axis of the pump. This is in contrast to radial-flow pumps, where the fluid is thrown outward from the impeller. In axial-flow centrifugal pumps, the rotor functions like a propeller, moving fluid along the pump's axis. Diffusion vanes are often used in the discharge port to manage the fluid's rotational velocity imparted by the propeller. These pumps are also used as compressors for gases.123
