Mixing High Viscosity Fluids With Double-Helix Impellers

A double-helix impeller is commonly used to blend high viscosity fluids operating in a laminar flow regime. The helical ribbons in this impeller are designed for close wall clearance. They operate at relatively slow speeds rotating in a direction to create fluid movement up along the wall. The fluid returns down the center of the tank providing overall blending in the tank. They are many high viscosity polymer applications mixed with helix impellers with viscosities exceeding 500,000 cps. This video demonstrates the action of a high viscosity fluid (10,000 cps) when mixed by a 12.5” diameter double-helix impeller in a 13.25” diameter tank. The helix is operating in a laminar flow regime. A colored dye is added to allow visualization of the blending with fluid flow up along the walls and down the center. The blend time for this high viscosity fluid is relatively short.
