Types of Mixer Impellers

Mixing propellors to suit your agitation requirements

 

Whether you are mixing high or low viscosity fluids, it is important to choose the right type of impeller to suit your process. The right agitator impeller for your application will result in optimal turnover of your tank or pipeline contents. FluidPro offers a wide range of mixer impeller types to suit a range of fluid types, viscosities, industries and applications.

Mixer Impeller Options

Axial Flow Agitator Impellers

Axial flow impellers are low shear impellers typically suited to low to medium viscosity fluids. Featuring inclined blades, they are ideal for mixing, liquid blending and maintaining solids in suspension. Axial flow creates an up-and-down motion, providing efficient top-to-bottom mixing within your tank.

FluidFoil Axial Flow Impellers

FluidFoil impellers feature 30° angled propeller blades, which are highly suitable for low viscosity applications, or for pushing fluid downwards to achieve solid suspension.

These square-edged axial flow blades are designed to suit liquids and other substances of higher viscosity at lower speeds.

Featuring a rounded blade similar to those found on boats, marine blades provide axial flow suitable for high-speed, low-viscosity applications.

Radial Flow Impellers

Radial flow impellers feature straight blades, meaning they create a sideways motion when they rotate, rather than shifting the liquid up and down. This sideways motion results in higher shear stress. Radial flow impellers have a lower tank turnover flow than axial flow and are suitable for dispersion processes and combination blending of gases, liquids and solids.

R490 radial flow propellers move fluids sideways for lower levels of fluid. They can also be used for inline mixing applications, such as in an inline dynamic mixer, to blend fluids directly within a pipeline.

Collapsible Blade Impellers

Folding or collapsible impellers feature blades that can be folded inwards, and which open when the shaft begins to rotate. They are a convenient solution for tanks, drums or other vessels with a small opening, such as a bung hole, where typical impellers cannot fit. Folding impellers fit through the bung opening and will not open until the agitator is switched on.

Folding Axial Flow Impeller

The folding FluidFoil axial flow mixer impeller is designed for portability, and for mixers with a limited tank opening. This makes them suitable as a tote mixer impeller, such as for an Intermediate Bulk Container (IBC).

Folding radial flow impellers allow for radial flow in vessels with a narrow or small opening. These folding turbines are ideal as a drum mixer propeller.

Small folding turbines can be suitable for smaller, air-driven mixers (such as the FluidPro DM-60 IBC mixer), suitable for mixing applications with a lower viscosity. .

High Shear Impeller Options

High shear force is required to break down large agglomerations, typically in dispersion processes. Rather than traditional impellers, discs or slotted heads are used for these applications.

High Shear Dispersion Disc

High shear dispersion discs feature ‘teeth’ for breaking down larger particles, so they can be dispersed evenly through a mixture. Working at high revolutions per minute (rpm), they provide high velocity and shear force, allowing you to combine a variety of materials with different particle sizes to create a homogenous mixture.

Slotted head for an emulsifier
Slotted Emulsifying Head

A slotted emulsifying head is ideal for breaking down large particles, so they can blend with smaller ones and create a uniform mixture. Particles are sucked through the slots of the head by vacuum suction, where the change in pressure state breaks them down. This is ideal for converting powders or solids to liquid mixtures, or blending immiscible products.

Specialty Mixer Impellers

We understand that your operational needs are unique, and we are able to offer a range of specialty impellers, tailored to your exact processes and requirements.

Viscopro specialty impellers
Viscopro

Featuring a funnel-shaped design, Viscopro is designed to propel high viscosity fluids at high velocity, or to mix fluids of variable velocities, such as ketchup, custard and hair products such as shampoos.

A specialty UltraShear pumping propellor
UltraShear

A specialty axial pumping impeller which creates flow in opposing directions. This design is ideal for medium viscosity fluids or gaseous substances with large mass transfer coefficients.

Static Mixer Baffles

Inline static mixers do not feature any moving parts, instead relying on the shape of the baffles and the flow of the liquid itself to create liquid turbulence. FluidPro’s static mixer baffles allow you to blend fluids seamlessly within your existing pipeline.

Shaft and Impeller Materials

Different shaft and impeller materials can be required depending on your application, to ensure suitable lubricity, food safety or corrosion or chemical resistance. FluidPro mixing impellers can be made from a range of materials, including:

  • 316 stainless steel
  • Titanium
  • Mild steel
  • Teflon
  • Polymers (such as PVC or HDPE)
