Dispersion Impellers & Mixing Blades
Blade Depot® carries the full range of impeller types — including 304 and 316 stainless steel impellers, hard coated impellers, and Polyblade® polymer dispersing impellers, not only Polyblade® products. Available styles include high shear impellers, high vane impellers, propeller blades, turbine blades, high viscosity blades, and custom impellers built to specification. Blade selection depends on tooth pattern, tank diameter, viscosity range, and material composition.
Blade & Impeller Lines
Polyblade Impellers
Patented polymer dispersing impellers that are far safer than metal blades, which can sharpen over time. They also reduce metal contamination, last far longer due to the abrasion-resistant materials, and are now available in aggressive designs to dramatically increase production rates. Pharmaceutical grade polymers are available.
High Shear Impellers
Saw-tooth type high shearing metal blades in a variety of designs, some of which include high pumping. Popular for high-speed dispersion of pigments, fillers, and resins in paint, ink, and coatings where shear is needed.
High Vane Impellers
High Vane Impellers can have axial and/or radial flow vanes that move the full batch at minimal shear, focusing more on pumping — suited to coatings letdown, emulsification, and clay processing.
High Viscosity Blades
Close-clearance blades that follow the vessel wall for high-viscosity, low-shear mixing and heat transfer without product buildup. Also used where air entrainment is not desired. High Viscosity Blades can take the shape of an Anchor, Gate, Helical, Bow Tie, and Butterfly.
Turbine Blades
High Efficiency, Axial Flow, and Radial Flow flat-blade turbines for excellent mixing of fluids and/or gas as well as solids suspension in taller vessels.
Propeller Blades
Marine-style propeller impellers that generate axial flow for bulk fluid movement and blending at lower shear, from laboratory to production diameters.
Custom Impellers
Built to specification — custom tooth pattern, diameter, material of choice, and modifications to existing blades and impellers. Also available are modifications to standard lines, such as a variety of helical blade designs or modifications to the Polyblade designs.
Blades Built to Your Equipment
Blades ship with matched plate and hub configurations — including clover-plate and internal-plate builds — sized to your existing shafts and mixers. Send your equipment specifications and we will match the blade geometry, material, and mounting.
