Product details

Our GP Reeves GUS unit incorporates a patented process designed to find and remove any grease that contains air bubbles from your system. The system’s air-purge test chambers have a specialized piston that draws small segments of grease from the supply and tests them for air. Grease containing air is purged, while airless grease continues through the dispensing system. GUS is available with single or dual test chambers, based on the required grease flow rate. Optional outlet accumulators are also available and are used to hold pressurized grease material after testing. The use of an outlet accumulator, or in some cases, a second test chamber, can allow your system to continue operating during a drum or pail change.

One GUS system can feed multiple dispensers with airless grease. This process is available in multiple sizes, includes a controller, and has valve stack options available via part configurator. GUS is manufactured under US patent number 6,053,285.
