Circumferential Piston Pumps

Wright Pump's TRA10 and TRA20 series circumferential piston pumps are drop-in replacements for Waukesha® U1 and U2 series pumps, respectively. Wright TRA10 series are the traditional workhorse pumps designed for strip-clean (C-O-P) applications. 

The TRA20 series are designed for high hygiene applications, using O-ring sealed rotors and rotor retainers, and offer an optional Clean-In-Place design with internal porting to allow vigorous flushing through all internal chambers.  TRA20 series pumps also allow higher pressure capabilities than TRA10 series.

Photos illustrate some of the many configurations available.

The table below provides a cross reference between Waukesha and Wright Pump model numbers, with nominal performance ratings.
