Wright Circumferential Piston Pumps

Wright Pumps conform to 3-A standard 02-09

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. The table below provides a cross reference between Waukesha and Wright Pump model numbers, with nominal performance ratings.  Photos illustrate some of the many configurations available.
