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.

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. Mixing impellers, Axial Flow Turbines, Radial Flow Turbines, Mixing Propellers, Hydrofoils, Steep Pitch Mixing Propellers, and more.  Call us at (812) 202-4047 or contact us through the website to get a same day answer to your question.

Ultra Shear Dispersion Blade, 2in Dia, 1/4in CH

Ultra Shear Dispersion Blade, 2in Dia, 1/4in CH

USB020025 $71

Ultra Shear Dispersion Blades rotate at high RPMs to facilitate the quick impartation of solids at a fine grind. The liquid contacts the blade and moves outward to to flow over the teeth breaking the agglomerations into increasing smaller particles. The Ultra Shear 304 stainless steel blade includes extra surface area at the blade tip to facilitate even higher levels of shear in the product. This leads to even faster throughput! Typically used in paints and inks, they are now being used in a variety of industries for increased efficiency.

2" Axial Flow Turbine w/ 3/8" Bore

2" Axial Flow Turbine w/ 3/8" Bore

LIMA20375 $50

316 SS. The axial flow turbine is a classic medium shear impeller. Very effective in both low viscosity and high, this axial mixing blade allows a mixer to the break up agglomeration and impart solids effectively. These axial mixing blades will draw more power per volume than the propellers or hydrofoils as motor power is converted to shear energy. Mixer Direct's Lab Axial Flow Turbine features a 2" blade, a 3/8 bore, and a hub with set screw attachment for easy blade installment.

2" Lab Hydrofoil w/ 3/8" Bore

2" Lab Hydrofoil w/ 3/8" Bore

LIMH20375 $39

These impeller stirrer blades are made with 316L Stainless Steel. High pumping per horsepower. Low shear.

2" Radial Flow Lab Impeller w/ 3/8" Bore

2" Radial Flow Lab Impeller w/ 3/8" Bore

LIMR20375 $50

The Radial flow turbine creates a radial flow pattern moving away from the impeller, towards the sides of the vessel. The flow of this stainless-steel turbine impacts the side and moves in either an upward or downward direction to fill the top and bottom of the impeller and be ejected once more. Some applications benefit greatly from this type of action, namely gas dispersion. Radial flow turbines have a high horsepower draw relative to axial flow turbines and other axial flow impellers. Mixer Direct's Lab Radial Flow, Stainless-Steel Turbine features a 2" blade, a 3/8" bore, and a hub with set screw attachment for easy blade installment.
