Impellers

The purpose of mixing impellers is to transfer the energy provided by the motor to the product in the most efficient way in order to produce the desired effect in the least amount of time. Also called agitator blades, each mixing impeller type converts the energy given to it 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 more of the energy into shear than the hydrofoil but still mostly produces motion.

Contact Us

The axial flow turbines and radial flow turbines devote a higher ratio to shear and a dispersion blade is almost completely devoted to shear production. Mechanical considerations may also affect the agitator blade selection as in the case of a folding impeller being utilized to fit into a tank through a small aperture.

MixerDirect has recently released MixerGenius v2.1, proprietary software developed to allow our sales engineers to quickly get to an engineered solution for your application. Agitator blade sizing can be quickly accomplished while you are on the phone for almost any of the types of impellers for sale that we carry.
