Consisting of a propeller-like impeller, an axial flow pump rotates within a cylindrical casing or pipe. As the impeller spins, it pushes fluid parallel to the pump's shaft, creating flow in an axial direction.

Key features of axial flow pumps include:

1. High flow rates with low head (pressure)

2. Propeller-shaped impeller with few blades

3. Fluid movement parallel to the pump shaft

4. Typically used for applications requiring large volume transfer

These pumps are commonly used in scenarios such as:

- Flood control and drainage

- Irrigation systems

- Wastewater treatment plants

- Cooling systems for power plants

Axial flow pumps are efficient for moving high volumes of liquid when significant pressure increase is not required. Their performance characteristics differ from other pump types, with power consumption increasing as flow decreases.
