PetFLEX™ Twin Screw Extruders

One of Wenger's innovative FLEX™ series extrusion systems 


Possibly the most flexible and versatile Wenger extrusion system ever designed for pet foods and treats.


  • Two available models:  PFX-3000, PFX-600
  • Excellent for standard kibble, premium and high fresh meat kibble, and treats
  • 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 screw profile allows for optimizing 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 very high levels of fresh meat inclusion (fresh meat slurry lines highlighted in red on graphic above)
  • Intuitive and interactive control interface provides operators with precise control and montoring of production
  • Flexible to accomodate alternative and unconventional ingredients
  • Superior product uniformity and density control

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.
