Wright Flow Technologies TRA20 Series

Wright Flow Technologies TRA20 serie is a positive displacement circumferential piston pumping technology, designed for high hygiene applications. The TRA20 series offer an optional Clean-In-Place (C-I-P) design with internal porting to allow vigorous flushing through all internal chambers. TRA 20 series are dimensionally interchangeable with Waukesha® for comparable models. This makes it very easy for the customers to upgrade their pumps.


  • Time tested and proven circumferential piston design.
  • Exceptional engineering and manufacturing quality.
  • Parts are interchangeable with Waukesha® U2 series pump parts.
  • Wright Flow Technologies TRA®20 pumps are drop-in replacements for equivalent sized Waukesha® U2 pumps.
  • Wright Flow Technologies can remanufacture TRA®20 series or Waukesha® U2 series pumps up to three times.
