Dispersion Blades & Mixing Impellers
Blade Depot® carries the full range of impeller types — including 304 and 316 stainless steel impellers and Polyblade® polymer dispersing impellers, not only Polyblade® products. Available styles include Cowles blades, high vane blades, propeller blades, turbine blades, anchor and gate blades, and custom impellers built to specification. Blade selection depends on tooth pattern, tank diameter, viscosity range, and material composition.
