PLC, Portionmeter Controlled, fix ratio meter mix dispense system. Dispense system has proportional Pneumatic control to provide automatic adjustment during material dispense (from manual)

This system is clean and guaranteed to be in good working condition. MESSAGE ME FOR A VIDEO OF THE PUMPS WORKING. I am no expert in this equipment. It looks to me that there is the one Meter Mix unit that hooks to the Dispense unit and then a third unit that has its own mixing system with A and B mixers that can add color...but again please do your own research. Graco bought this company but kept equipment as is. AUCTOIN COMES AS PICTURED WITH ALL 3 PIECES! If you search you can find the manuals for the Meter Mixer units.
