Portable Mixers

ADVANCED DESIGN

• Gear drive and direct drive models.

• Rugged yet lightweight construction.

• Wide range of operating speeds.

• Clamp and mounting configurations for open or closed tanks.

• Shaft diameter, materials, and coupling combinations for your specific application.

• Industry standard, easy mount, NEMA motors. Variable speed, air, or electric options.

• Extensive array of impellers for any process requirements.

• Easy installation and low maintenance.

SUPERIOR ENERGY EFFICICIENCY

Our portable mixers have a special advantage over other mixers.Using a model of high torque and low speed, our 

portable mixers apply more torque to the mix for the same energy consumption or, put another way, our portable 

mixers apply the same torque while consuming 20% LESS energy. Higher efficiency means lower costs.

INNOVATIVE SOLUTIONS

Each process has unique qualities and characteristics. We work 

closely with you to provide a mixing solution tailored to your needs 

for optimized process results.

Impeller Styles

Features:

Low Solidity Hydrofoil

Low Solidity Hydrofoil is the most flow efficient 

impeller for low viscosity. Maximizes flow with 

ability to add shear if required.

CounterflowTM Impeller

CounterflowTM Impeller provides lower 

power and high torque mixing - saving 

energy. Dual pumping action establishes 

a flow pattern similar to low viscosity fluid.

Stabilizer Rings

Available on any lower propeller for

smooth operation of long shafts or 

for drain down situations.

Steep Pitch Propeller 

Steep Pitch Propeller (1.5 to 1) is standard 

for a wide range of applications. Provides 

excellent flow and blending.

Folding Propeller

Folding Propeller passes easily through 

bung hole of 55 gallon drum and opens 

automatically under power. Sizes from 3” to 5”.

Pitched Blade Turbine

Pitch Blade Turbine is an ideal choice when 

both flow velocity and fluid shear are required. 

Its smaller diameter is well suited for high 

intensity liquid blending.

And more. We have an impeller that’s 

right for your application needs.
