Figure 3: Turbulent Flow Impellers Axial flow impellers are very useful in mixing solid-liquid Axial flow pumps are not well-suited for handling media with solids, but can be used when designed with the proper impeller type. This flow pattern develops using a center mounted axial flow impeller in a “fully baffled” tank. Unlike radial-flow pumps, where fluid moves outward from the pump's center, in axial pumps, the fluid flows in the same direction as the pump shaft. Compact Design: Axial impeller are generally more compact than other types of impellers, saving space in equipment and installations. The figure below shows the flow path through these types of pumps as well as their specific speed ranges. By understanding the types of blower impeller available—radial, axial, and mixed-flow—you can better align your equipment with performance goals. What is Axial flow Pump? An axial flow pump is a type of centrifugal pump in which the fluid enters and exits the pump in a parallel direction to the impeller. Commonly used in gas dispersion and emulsification applications, they suit high-viscosity liquids. This equipment's main feature is the ability to generate upward and downward axial flow. The differences come to light when you consider your entire mixing process and all related components. Shear is low and there is little vertical flow. In waste treatment, surface aerators typically use axial flow impellers, and there are many types of draft tube aerators that use axial flow impellers in a draft tube. The type of flow pattern set up by a typical axial-flow impeller is illustrated in Figure 8. Multi-stage axial fans with contra-rotating impellers can be supplied up to 1400mm diameter.
