Application-Specific Impeller Selection
45-Degree Pitch
45-degree pitch impellers are used for both turbulent and laminar flow applications. They perform particularly well in applications where viscosity changes significantly. The 45-degree pitch impeller can be used when solids are added to the tank regularly.
Hydrofoil
Hydrofoil impellers offer the lowest shear of all impellers. The design of UET Mixers hydrofoil impellers provides approximately 200% more pumping capacity than a conventional 45-degree pitch impeller. This additional mixing capacity is achieved without requiring additional power or the cost of additional mechanical equipment. They are suitable for a wide range of applications.
Propeller
Propeller impellers, or "marine" style, are typically used in portable mixers for small-batch applications. They are ideal for highly turbulent applications.
Intermig
A specialized axial-flow impeller that provides a counter-flow pattern in highly viscous fluids.
90 Degrees
90-degree impellers are best for laminar flow applications, often in dispersions. They are a good solution near the bottom of a tank.
Rushton
The right solution for adding low concentrations of immiscible liquids or gases.
Disperser
As its name indicates, this impeller is ideal for dispersions. It is significantly more efficient in gas dispersion applications than the Rushton impeller. It is also suitable for liquid-liquid dispersions.
Gas Dispersion
For gas dispersion applications, the gas dispersion impeller is an improvement over the traditional Rushton impeller. Compared to the Rushton's flat-blade design, the curved blades of the gas dispersion impeller allow up to five times more gas flow.
Shear
A good solution for applications that require high shear. Shear impellers are often used together with a secondary "pumping" impeller to assist in tank turnover.
Anchor
An excellent solution for heat transfer applications with high-viscosity fluids. As an option, Teflon scraper blades are often added for difficult applications.
Ribbon
Ideal for extreme viscosities (up to 1,000,000 cP under agitation), as well as for mixing fluids with large viscosity differences.
