TRA20 Pump

TRA20 pump series of rotary circumferential piston pumps are dimensionally identical, drop-in replacements for the Waukesha Pump Universal II (U2) series.

The TRA20 is designed for high hygiene applications.

The TRA20 pump uses O-ring sealed rotors and rotor retainers and offers an optional ‘Clean In Place’ (CIP) design with internal porting to allow vigorous flushing through all internal chambers.
