What is the difference in impellers?
Each impeller type deals with the energy given to it by the motor in a different way. A hydrofoil converts most of the energy into motion of the product and very little into shear. A three bladed propeller will convert most of the energy to product motion, but a higher percent to shear than the hydrofoil. The axial flow turbine devotes an even higher ratio to shear and a dispersion blade is almost completely converted to shear. All of our mixers are outfitted with a particular impeller based on how the mixer is used. Hydrofoils are used for low viscosity products and have a great efficiency. Propellers are used in low volume medium viscosity liquids. Axial flow turbines are used in medium to heavy viscosities. Radial flow turbines are used in circumstances, like gas dispersion, where the product must be forced against the walls of the vessel. Dispersion blades are used where solids must be imparted into liquids aggressively. If you need assistance when choosing the right impeller conta
