What is the purpose of having different type of impellers for fluid mixing?
Their purpose is to transfer the energy driven by the motor to the contents of a tank as quickly and efficiently as possible. Each type of impeller can be categorized by its flow pattern, whether it’s an axial pattern {parallel to the blade} or a radial pattern {perpendicular to the blade}.
What are different flow patterns in mixing?
The most common flow patterns in mixing are axial (down and up) and radial (side to side) flow. These flow patterns also describe the generic classes of impellers: axial and radial.
Which type of impeller can be used for fluids of high viscosity?
double-helix impeller
A double-helix impeller is commonly used to blend high viscosity fluids operating in a laminar flow regime. The helical ribbons in this impeller are designed for close wall clearance. They operate at relatively slow speeds rotating in a direction to create fluid movement up along the wall.
Which type of impeller is used in liquid agitation?
Paddle impellers range in design from a single, flat paddle on a vertical shaft to a battery of multi-blade flocculates mounted on a long, horizontal shaft. These impellers run at a slow to moderate speed (2 to 150 rpm) and are used to mix high viscosity liquids.
What are radial flow impellers?
Radial flow impellers create a side-to-side fluid motion that produces high shear rates and a relatively low pumping number. They’re suitable for use low-level mixing and elongated tanks, among other applications.
What are the two types of impellers?
Pump Impellers – The Types & Their Impact
- Open impeller.
- Semi-open impeller.
- Closed impeller.
- Vortex impeller.
- Cutter impeller.
How do you mix high viscosity liquids?
Successful Mixing in Viscous Flow In high viscosity mixing, you must have a mixer that moves your substances at a high intensity with a high degree of interlacing as well. Interlacing creates angles and pushing movement of the impeller to force two streams of laminar motion to collide into one another.
What is an impeller in a mixer?
After all, it is the component that physically does the mixing. Impellers are selected for a particular application by their unique shear and fluid flow patterns, resulting in just the right mix. Impeller types can be categorized into two basic categories: axial flow, and radial flow.
What are the different types of impellers?
Impeller types can be categorized into two basic categories: axial flow, and radial flow. Axial flow impellers have an up and down flow pattern, ideal for applications where solids suspension or stratification is a challenge.
What mixing impellers does ProQuip offer?

What is the best impeller for high flow applications?
Hydrofoil: The hydrofoil impeller offers the best high flow design. It is known for its low turbulence, and is excellent for shear sensitive applications. Radial flow impellers generate a side to side flow pattern.
