Product Description

MRC Impeller No. 13

is a 50 mm (1.97 in.) three-blade axial-flow propeller that produces strong top-to-bottom circulation for liquid blending, powder incorporation, solids suspension, heat transfer, and other low-to-moderate-viscosity mixing applications.

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 propeller-driven circulation 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 flow 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, heating or cooling surfaces, immersion 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.
• Rounded propeller-style blades guide liquid more smoothly than straight radial turbine blades.
• Tall sleeve-style hub provides an extended shaft-engagement area compared with a flat mounting plate.

FAQs

What type of impeller is the MRC Impeller No. 13?

It is a 50 mm (1.97 in.) three-blade axial-flow propeller designed to create strong top-to-bottom vessel circulation.

What is axial flow?

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

Can this propeller create a surface vortex?

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