Abstract
A fluid dispensing apparatus for automated dispensing high-viscosity fluids for mixing applications, such as dispensing of pigment concentrates for mixing screen printing inks and paints includes a rotatable carousel containing a plurality of different pigment concentrate supplies. The carousel is selectively rotated into a dispensing position in alignment with a dispensing pump and the pump is actuated to dispense through a dispensing valve assembly associated with each pigment concentrate supply. The dispensing valve assembly includes a pair of dispensing valves having different valve orifices so that the pigment concentrates may be dispensed in coarse and fine iterations into a container for mixing.
