PetFLEX™ Twin Screw Extruders

One of Wenger's innovative FLEX™ series extrusion systems 


An excellent choice for high volume production of limited ingredients diets to complex fresh meat diets. . .

      and everything in-between.


  • Two available models:  PFX-3000, PFX-600
  • Produces standard kibble, premium and high fresh meat kibble, and treats
  • Target output up to 11,000 kg/hr  (PFX-3000)
  • High thermal energy design, flexible for medium- and high-sheer applications
  • Pre-conditioner steam levels (using the Wenger HIP) can be up to 12%.
  • Unique twin screw profile allows for optimized steam injection in barrel
  • Excellent durability - the unique metallurgy along with specially designed rotating elements and barrel results in improved wear life and unmatched system uptime
  • Enhanced mixing through the preconditioner and extrusion barrel
  • Allows for fresh meat inclusion (fresh meat slurry lines highlighted in red on graphic above)
  • Intuitive and interactive control interface provides operators with precise control and monitoring of production
  • Flexible to accommodate alternative and unconventional ingredients
  • Superior product uniformity and density control
  • Can be used to produce high volumes of any type of feed. For aquatic feeds, including micro size feeds, this technology is available with the Wenger AquaFLEX extrusion line

The PetFLEX design enables production of a wide range of products from the same screw set-up, improving uptime and efficiency




Wenger's FLEX™ extruders use a unique screw configuration to create processing zones that allow for higher shear and high thermal energy transfer.  This results in stable, uniform production of a wide variety of products, without “surging” that often happens with single screw designs.
