Corrugated Plate Static Mixer (Type GV)

The GV static mixer has been used successfully in turbulent flow applications for over 35 years. It is a high performance inline mixer capable of mixing low viscosity liquids, blending gases, dispersing immiscible liquids and creating gas-liquid dispersions with a very high degree of mixing in a short length.

Mixing Capabilities
  • Blend low viscosity liquids
  • Disperse immiscible liquids
  • Mix gases
  • Contact gases and liquids
  • Mixing of liquids, chemicals and additives in water treatment and chemical plants
  • Dispersing immiscible liquids such as crude oil and water in refineries for extraction applications
  • Mix gases in front of catalytic reactors
  • Contact air and liquids for oxidation
Geometric Configuration Variables
The GV static mixer is versatile because it has many geometric configuration variables that can be used to impact the intensity of mixing created within any given pipe diameter and create mixing solutions that are difficult to achieve with any other technology:
  • Standard GV static mixers are constructed with 5-corrugated plates across their diameter with a 45o corrugated plate angle relative to the pipe axis (Figures #1 - #2).
  • Number of layers can be varied within a given pipe diameter (Figure #3) to intensify mixing and contact
  • Corrugation angle can vary (Figure #4) to affect intensity of mixing and pressure drop.
  • Spacers between mixing elements take advantage of empty pipe turbulent mixing created by the upstream motionless mixing element (Figure #5) at no additional pressure drop.

Figure #3: The mixing intensity and pressure drop of the GV static mixer may be adjusted by varying the number of corrugated layers in any specific pipe diameter (left side: standard 5 layers; middle: 8-layers; right side: 12 layers).

Figure #4: The mixing intensity and pressure drop of the GV static mixer can be adjusted by varying the corrugation angle relative to the pipe diameter (left side: standard 45o angle; right side: 30o angle)

Figure #5: Spacers can be added between mixing elements to take advantage of the turbulent eddies created downstream of a mixing element at no additional pressure drop and at modest cost.

History of GV Static Mixing Structure
The corrugated plate static mixer design was invented by Sulzer Chemtech of Winterthur, Switzerland in the early 1980’s who trademarked the design as the SMV* static mixer. Sulzer published a tremendous amount of fundamental high quality R&D work on the SMV structure and commercialized the SMV static mixer in tens-of-thousands of successful installations. The founders of StaMixCo held key technical and management positions in the Koch Engineering (USA) - Sulzer Chemtech (Switzerland) team that commercialized the SMV static mixer. The GV static mixer in this web page is StaMixCo’s version of the Sulzer SMV static mixer.
