WebMay 15, 2024 · Third Method – Flow of Material. 1. With a clockwise rotating shaft a left-hand propeller will direct your material flow downward. A right-hand propeller will direct your material flow upward. 2. A counterclockwise rotating shaft will produce the opposite flow results. These methods work for our square pitch and steep pitch propellers. Web3.2. Propeller and Pfaudler Impellers. The blades of the propeller and pfaudler impellers do not have sharp edges.
