Product Description

MRC Impeller No. 4

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

Applications

Liquid Blending

Provides radial agitation for combining low-and-moderate-viscosity liquids in laboratory mixing, formulation, reaction-development, and quality-control workflows.

Powder and Particle Dispersion

The long exposed blades generate localized shear that can assist with powder wetting, additive distribution, catalyst dispersion, fine-particle suspension, and weak-agglomerate breakup.

Gas-Liquid Mixing and Aeration

Suitable for laboratory aeration, gas absorption, oxygen-transfer studies, and other applications where gas must be distributed through a low-viscosity liquid.

Formulation and Process Development

Useful for coatings, inks, adhesives, resins, specialty chemicals, and other formulations that benefit from radial circulation and concentrated turbulence near the impeller.

Features

• Six long, straight blades generate primarily radial flow and localized turbulence.
• Open construction allows fluid to pass more freely between the upper and lower sides of the impeller than a full-disc turbine.
• Exposed blade length supports powder wetting, particle dispersion, and rapid local blending.
• Compact central mounting geometry reduces obstruction through the center of the mixing zone.
• The 50 mm (1.97 in.) diameter is suitable for laboratory vessels and small-scale mixing trials.
• Flat, symmetrical blade geometry may permit similar operation in either rotational direction, subject to confirmation that the blades are unpitched.

FAQs

What type of impeller is the MRC Impeller No. 4?

It is a 50 mm (1.97 in.) six-blade open turbine with long radial blades and no full supporting disc. Its geometry is designed to produce radial flow and localized shear.

How does an open turbine differ from a disc turbine?

An open turbine does not use a full circular disc behind the blades. This allows more fluid movement between the upper and lower sides of the impeller, while a disc turbine creates a more sharply divided radial discharge and can better intercept gas introduced below the impeller.

Warranty

The MRC Impeller No. 4 is warranted against defects in materials and workmanship under normal use and service. For warranty assistance, replacement parts, product support, or application guidance, contact LabGear USA technical support. Warranty valid for 12 months.
