Hygienic Circumferential Piston Pumps

A circumferential piston pump (or rotary piston pump) is similar to a lobe pump, but uses special non-galling alloy rotors to offer strong self-priming capabilities and gentle handling of shear-sensitive fluids and slurries.

Circumferential piston pumps (or rotary piston pumps) are food grade industrial pumps and feature a stainless steel 316 body with rotors constructed from a non-galling stainless alloy. The close-clearance operation of the rotors is critical to the performance of the pump and allows gentle handling of high viscosity, shear-sensitive fluids. These pumps can be used for pumping butter & fats, fondants, icing, concentrated pastes, fruit concentrates, whole foods and other fragile or high viscosity materials.

TRA10 Circumferential Piston Pumps

TRA10 Circumferential Piston Pumps

TRA10 circumferential piston pumps represent the highest industry standard for sanitary applications and are suitable for all industries. The TRA10 pump is 3A certified as standard.

Using proven pumping principles established for many decades, these pumps are in use around the world and their gentle action on shear-sensitive liquids and slurries with soft solids make them the preferred pump type for food, beverage, dairy, canning, bakery, pharmaceutical processing as well as challenging chemical and industrial applications.

The TRA10 pump series of rotary positive displacement circumferential piston pumps is regarded as the traditional workhorse pump designed for strip-clean (Clean Out of Place) applications. TRA10 models are dimensionally identical, drop-in replacements for the equivalent model within the ubiquitous Waukesha Pump Universal I series but with important enhancements as standard.

TRA20 Circumferential Piston Pumps

TRA20 Circumferential Piston Pumps

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 and is 3A certified as standard.

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.

TRA20 series pumps also allow higher pressure capabilities than the TRA10 series.
