With increased deck heights, heavier ink viscosities, and chamber systems, there is a greater need to examine the entire plumbing system that gets the ink from the container to the print deck. Fittings: Many fittings cause restrictions, and 90o elbows are among the worst. Are all your valves and fittings “full port”, or is the internal diameter smaller than the connection size? Do your...

This variety of choices lets you configure your system to meet specific printing and press requirements, whether water, solvent-based or UV. MOTOR OPTIONS Air Properly installed and maintained air motors are inherently explosion-proof, making them ideal for use with solvent-based inks. Ink flow is easily controlled by varying pump speed. With water-based materials, this eliminates the need for valves and bypasses that can contribute to foaming. Standard features include needle valve to permit infinitely variable...
