Product Description

MRC Impeller No. 1

is a Rushton-type six-blade disc turbine that produces strong radial flow and localized turbulence for gas dispersion, liquid-liquid blending, powder incorporation, and other high-shear mixing applications. Available in 50, 65, 75, and 85 mm (1.97, 2.56, 2.95, and 3.35 in.) diameters.

Applications

Chemical and Process Development

Supports laboratory-scale reaction development, solvent blending, liquid-liquid dispersion, catalyst distribution, and other mixing processes where strong radial discharge and localized turbulence are desirable.

Gas-Liquid Mixing and Aeration

The disc-turbine geometry can help disperse gas introduced below the impeller by directing bubbles toward the turbulent blade region. Potential uses include aeration studies, gas absorption, fermentation development, carbonation, and gas-liquid reaction testing.

Formulation and Product Development

Useful for incorporating powders, dispersing low-to-moderate-viscosity ingredients, reducing weak agglomerates, and developing emulsions or suspensions in coatings, adhesives, cosmetics, specialty chemicals, and related formulations.

Research and Quality-Control Laboratories

Provides a consistent impeller family for comparative mixing trials, scale-development studies, sample preparation, material evaluation, and testing the effect of impeller diameter on circulation, shear, and mixing time.

Features

• Strong radial discharge: Directs liquid outward toward the vessel wall to create defined upper and lower circulation zones.

• High localized turbulence: Six upright blades generate trailing vortices that support bubble breakup, droplet dispersion, and rapid mixing near the impeller.

• Disc-turbine construction: The central disc separates flow above and below the impeller and helps direct material through the active blade region.

• Four diameter options: Allows the impeller to be selected according to vessel diameter, batch geometry, torque availability, and required mixing intensity.

Specifications

FAQs

What type of impeller is the MRC Impeller No. 1?

It is a Rushton-type six-blade disc turbine. The horizontal disc and upright radial blades produce a primarily radial flow pattern with strong localized turbulence near the impeller.

Is this impeller suitable for high-viscosity materials?

It is generally better suited to low-and-moderate-viscosity materials than to thick gels, heavy pastes, or highly viscous laminar mixtures. An anchor, gate, or helical impeller may provide better bulk movement in high-viscosity applications.

How do I select the correct impeller diameter?

Consider the vessel diameter, working volume, liquid viscosity and density, required circulation, available motor torque, rotational speed, and acceptable shear. Increasing impeller diameter can substantially increase power and torque demand, so compatibility with the overhead stirrer should be confirmed before ordering.

Is this the best impeller for shear-sensitive samples?

Not usually. Disc turbines generate relatively high localized shear. An axial-flow, paddle, or hydrofoil-style impeller may be preferable when gentle circulation or protection of fragile cells, crystals, or structured materials is the priority.
