Product Description

MRC Impeller No. 15

is a three-blade axial-flow propeller designed to produce strong top-to-bottom circulation for liquid blending, powder incorporation, solids suspension, heat transfer, and other low-to-moderate-viscosity mixing applications. It is available in 80, 100, and 120 mm (3.15, 3.94, and 4.72 in.) diameters for different vessel sizes and circulation requirements.

Applications

General Liquid Blending

Provides axial circulation for dilution, reagent preparation, pH adjustment, liquid-additive incorporation, sample preparation, and routine laboratory batch mixing.

Powder Incorporation

The broad pitched blades can help draw readily wetted powders, salts, catalysts, and formulation additives into the liquid and distribute them throughout the vessel.

Solids Suspension

Strong top-to-bottom circulation can help lift and recirculate fine or moderately settling particles in light slurries and laboratory suspensions.

Heat Transfer and Temperature Equalization

Bulk circulation repeatedly moves liquid past vessel walls, jackets, heating or cooling coils, and temperature probes to support more uniform batch temperatures.

Features

• Three broad pitched blades generate axial flow parallel to the stirring shaft.
• Produces strong top-to-bottom circulation for efficient bulk vessel turnover.
• Supports liquid blending, powder incorporation, solids suspension, and heat transfer.
• Broad paddle-style blades provide substantial surface area for moving liquid.

Specifications

FAQs

What type of impeller is the MRC Impeller No. 15?

It is a three-blade axial-flow propeller with broad paddle-style blades designed to create strong top-to-bottom circulation.

How should I choose an impeller diameter?

Choose according to vessel diameter, batch volume, required circulation rate, fluid properties, and available stirrer torque. Larger impellers generally move more liquid but place greater load on the shaft and drive.

What is axial flow?

Axial flow moves liquid primarily parallel to the stirring shaft, creating broad top-to-bottom circulation and efficient bulk mixing.

Can this impeller create a surface vortex?

Yes. High speed, shallow immersion, centered installation, or an unbaffled vessel may create a vortex and unwanted air entrainment. Deeper placement, lower speed, off-center installation, shaft tilt, or vessel baffles may help control vortexing.
