ABSTRACT:
A colorant dispenser having a modular design includes a colorant pump with abrasion resistant coating and needle bearings for a long pump life. The pump also includes a stepper motor for accuracy in pumping the colorant. The pump is mounted in the dispenser cabinet with colorant canister modules suspended in the cabinet. Valve modules dispensing colorant from the canister are packed in groups of four for easy installation. Nozzles from the valves are made of stainless steel with no joints to prevent separate colorants from leaking and mixing. The suspended canisters and the small stepper motors for each pump provide a cabinet with an open architecture conducive to easy repair and replacement of modular parts. A locking mechanism allows for easy transition of the pull-down shelf from resting flush against the cabinet, to being adjacent to the cabinet.
