Impellers

Hydrofoils

Brawn Mixer produces several hydrofoil variants for specific applications. These impellers produce good performance in turbulent flow applications including fluid blending and solids suspension. Hydrofoils pump low viscosity fluids very efficiently, more so than other conventional designs at constant power levels. Some designs have been developed specifically to perform well in laminar flow applications and even in high shear/mass transfer processes. The number of blades, and tip chord angle can be varied to meet your process requirements.

Pitched Blade Turbines

The traditional forty-five degree Pitched Blade Turbine (PBT) is a good all-purpose impeller for a wide range of applications. Brawn Mixer has refined the standard design through testing with varied pitch angles, blade width, and other adjustments by application. The results have been tremendous. When conditions call for more flow or varying the energy input, blade angle and shape can be adjusted to achieve the optimum results while retaining the effectiveness of the basic PBT concept.

Propellers

Propellers remain a simple option for small batch processes and certain processes requiring more shear.

Specialty Impellers

High-solidity (shown), anchors, scrapers, and helical impellers are just a few of the specialized designs Brawn Mixer has employed for high viscosity and non-Newtonian fluids.

High Flow Impellers: Blending and Solid Suspension

Ideal for blending, solids suspension, and dissolution applications. Designed to maximize strength at lower weights compared to other axial flow impellers, allowing for longer shafts and smaller shaft dimensions.

High Viscosity Blending

Accurately and intensely move product while running at the lower speeds required for high viscosity blending. Designed for the lower power required for bulk motion, blending and heat transfer applications especially in high viscosity and/or non-Newtonian fluids.

High Shear Solids Dispersion, Dissolution, Multi-Phase Dispersions and Emulsion

Convert the majority of the energy of the motor to shear force. Designed to excel at quickly breaking down solids and producing a fine uniform dispersion. These impellers can also be used in gas-liquid processes.

Close Bottom Clearance

Provide fluid motion at extremely low liquid levels and also keep on-center effluent nozzles clean for pump-out.
