• Westfall's High Shear Mixers create turbulent vortices for efficient mixing in a small space

Compact High Shear Model 2800

For complete and efficient short lay length pipeline mixing

Westfall’s high shear static mixer has a slim profile which allows simple drop-in installation in pipelines from 2″ to 120″. Alternate vortex shedding creates high performance mixing within a limited space. This is a full pipe motionless mixer into which up to six additives can be injected simultaneously or in specifically timed stages. High shear mixing also creates micro-bubbles for effective removal of salt from oil or oil from water.

Where space is limited, this affordable static mixer is ideal for municipal and regional infrastructure upgrades. It is available with a wide range of injection ports and quills, and a choice of 3 aperture sizes: .7 BETA, .8 BETA and .9 BETA.. The mixer resists fouling and requires little to no maintenance.

CFD Analyses by Alden Laboratories show a CoV range of .008 to .05.
K-Values range from 32.59 to 6.78.

Usage and Applications

3 Compact High Shear Plate Mixer Orifice Diameters

westfall 2800 mixer orifice diameters The 2800 Static Mixer comes in three orifice ratios so you can choose the one best suited to your injection materials and viscosities. With thicker materials, choose a larger orifice to inhibit nesting.

When tested at Alden Labs, the .7 beta opening showed a CoV of .008 and a K-Value of 32, with excellent mixing at 1-3 FPS.

The .8 beta opening showed .oo9 CoV and K-Value of 19 with excellent mixing at 3-8 FPS.

The .9 beta opening showed a CoV of .050 and K-Value of 7 with excellent mixing at 8-ll FPS.
