Our hope is that this will be a place to look-up mixing impeller types from many vendors.  If you are a mixing vendor, a mixing rep, or a graphic artist and you would like to see your impeller photos or CAD drawings here, with links to your site, please email us and let us know.  Also let us know if you see your impeller here, but you name it differently.  Information about these impeller designs will also be added below each picture, if available, and referenced to the source of that data.  Turbulent data is quoted here for fully baffled conditions, unless noted.  There will be a link to another page if more data is available.

Without baffles, most impellers styles impose a tangential flow pattern.  With baffles, most impellers show their true flow characteristics.  Impellers are sorted here by the flow patterns they were intended to create, radial flow impellers and axial flow impellers.  Click on any of these images for a larger picture.  If you can't find your impeller design here, see if it is stored under Special Impellers.  Impeller design data includes impeller dimensions, number of blades, turbulent power number, turbulent flow number, and impeller synonyms.  If you see a More Data link, click on it for flow pattern information and possibly non-turbulent power numbers (Np), flow numbers (Nq) and discharge angles as a function of Reynold's Number (Re).
