Radial flow impellers cause the media to flow perpendicular to the impeller's axis of rotation, generating a "side-to-side flow pattern" within the tank. Fluid ejected from the impeller moves towards the tank walls, then either upward or downward before returning to the impeller's center. This continuous motion thoroughly mixes the tank contents.
