The opportunity is for an overhead reservoir Goo Grinder that uses gear pumps and chain drive to meter two-part materials. It offers shot control, footswitch, static mixer manifolds, air or electric drive, and heaters, with output up to 1.5 quarts per minute and an adjustable fixed ratio range of 1:1 to 6:1 via drive sprockets. The unit includes two five-gallon reservoirs with drum feed and is intended for non-abrasive materials from 300 to 50,000 cps, or higher with an optional heater. Air-drive options provide variable speed on standard shop air with hand- or foot-toggled control, while electric-drive options are AC/DC 110V with fixed or variable speed and footswitch, toggle, or thumb-button control; both are compatible with shot-size control. Part numbers include GG-OH and related options for air drive, 5-gallon reservoirs with plate, pneumatic footswitch, and overhead grinder mixer.
