Product Description

MRC Impeller No. 9

is a three-blade formed propeller designed to produce strong vessel circulation and localized turbulence for liquid blending, powder incorporation, solids suspension, heat transfer, and other low-to-moderate-viscosity mixing applications. It is available in 50 and 90 mm (1.97 and 3.54 in.) diameters for different vessel sizes and pumping requirements.

Applications

General Liquid Blending

Provides broad circulation for combining low-and-moderate-viscosity liquids during dilution, reagent preparation, pH adjustment, sample preparation, and routine laboratory batch mixing.

Powder Incorporation

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

Solids Suspension

Strong bulk circulation may help lift and recirculate fine or moderately settling particles in light slurries and laboratory suspensions.

Heat Transfer and Temperature Equalization

Vessel-scale 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 formed blades provide substantial contact with the liquid during rotation.
• Cupped or deeply angled blade geometry appears designed to generate axial circulation with some radial discharge.
• Broad blade surfaces support strong fluid capture and vessel turnover.
• Localized turbulence assists with powder incorporation, particle distribution, and general blending.

FAQs

What type of impeller is the MRC Impeller No. 9?

It is a three-blade propeller. Its broad formed blades are designed to generate axial circulation with localized turbulence.

What is the benefit of the formed blade shape?

The broad, deeply angled blades provide substantial surface area for capturing and moving liquid. This geometry supports strong circulation while also creating moderate turbulence near the impeller.

How should I choose between the 50 and 90 mm sizes?

Choose according to vessel size, batch volume, desired circulation, fluid properties, and available stirrer torque. The 90 mm model should move more liquid but will generally place greater hydraulic and mechanical load on the stirrer and shaft.
