Product Description

MRC Impeller No. 2 

is a 50 mm (1.97 in.) six-curved-blade disc turbine that produces strong radial flow and localized turbulence for gas dispersion, liquid-liquid blending, powder incorporation, and other low- to moderate-viscosity mixing applications.

Applications

Gas-Liquid Mixing and Aeration

Supports laboratory aeration, gas absorption, oxygen-transfer studies, fermentation development, carbonation, and gas-liquid reaction work where bubbles must be directed through a turbulent mixing zone.

Liquid-Liquid Dispersion

Useful for blending immiscible liquids, developing emulsions, reducing droplet size, supporting solvent extraction, and increasing interfacial contact in laboratory-scale process studies.

Formulation and Materials Development

Provides localized turbulence for powder wetting, catalyst distribution, fine-particle dispersion, suspension preparation, and formulation work involving coatings, resins, adhesives, cosmetics, and specialty chemicals.

Research and Quality Control

Suitable for sample preparation, comparative impeller testing, process-development trials, mixing-time studies, and laboratory methods that require repeatable radial-flow agitation.

Features

• Six curved vertical blades generate strong outward fluid movement and localized turbulence.
• Radial-flow operation supports bubble breakup, droplet dispersion, and rapid mixing near the impeller.
• The central disc helps separate flow above and below the impeller while directing material through the blade region.
• Curved blades reduce drag and large trailing vortices compared with a traditional flat-blade disc turbine.
• The compact 50 mm (1.97 in.) diameter is suitable for laboratory vessels and small-scale mixing trials.
• Provides stronger localized shear than many axial-flow impellers, while axial designs may provide more efficient top-to-bottom circulation.

FAQs

What type of impeller is the MRC Impeller No. 2?

It is a 50 mm (1.97 in.) six-curved-blade disc turbine. Its blade and disc geometry produces primarily radial flow with localized turbulence around the impeller.

How does it differ from a flat-blade Rushton-type turbine?

Both designs produce radial flow, but the curved blades reduce drag and the intensity of large trailing vortices. This can provide smoother operation and potentially improved performance in aerated mixtures, depending on vessel design and operating conditions.

Is this impeller suitable for high-viscosity materials?

It is generally more suitable for low-and-moderate-viscosity liquids. An anchor, gate, or helical impeller may provide better bulk circulation for thick gels, pastes, and highly viscous mixtures.

Is this impeller appropriate for shear-sensitive samples?

It generates localized turbulence and may not be the best choice for fragile cells, delicate crystals, or other shear-sensitive materials. A gentler paddle, hydrofoil, or axial-flow impeller may be preferable.
