Uniflo Static Mixer (USM)

Get More from Your Process

Uniflo Static Mixers (USM) provide continuous in-line mixing for polymers, colorants, adhesives, and other fluids.  Highly polished, alternating 90° helical elements (alternating bow-tie twists) provide radial and axial blending over a short length to assure total mixing of compounded materials or to flatten melt temperature gradients.  USM mixers are made with high-strength elements, have no moving parts and produce an exceptionally low drag coefficient.  The mixing element is easy to remove for fast material changeovers and convenient maintenance.

Material flow over each element in the Uniflo Static Mixer simultaneously splits, blends and changes direction, ensuring a homogeneous output.

Each successive element splits the flow such that the number of splits squares the previous number. For example, the first element splits the flow in two.  The second element splits this result into four, the next into eight.  

  • A 6-element mixer splits the flow 26 (64) times. 
  • A 9-element mixer splits the flow 29 (512) times. 

Flow is non-linear.  Constant directional change within the static mixer moves material at the center out to the wall from the and wall inward to the center.
