Graymills Superflo® filters are specially designed for flexographic and gravure ink systems, providing effective filtration to eliminate quality problems from contaminants that can also damage costly anilox rolls. Sizes for all printing applications. Filters are available standard (models HFLT/HFST/HFNT) or as surge suppressors (models DDPSFST/DDPSFNT).
Superflo® ink filters are designed to overcome the typical pressure drop and reduced ink flow due to clogging that occurs with ordinary filters. A permanent magnet (optional rare earth megaMAG available) suspended over the intake port traps ferrous particles which find their way into the ink and diffuses the flow outward into the filter screen flutes. Filtered material is trapped on the inside of the removable/reusable stainless steel filter cartridge. To clean, just remove the cartridge. All contaminants come out with it. Graymills Superflo® filters are self-draining – no wasted ink or messy leftovers.
Stainless steel filter cartridges are available in four different mesh screens recommended for the following applications:
For narrow web flexo and rotary screen applications, and light to heavy viscosity inks, coatings, and adhesives (including UV/EB), requiring flow rates of 1.5 GPM or less. If flow requirements are above 1 GPM, consider model PPL for slower running speed and longer tube life. Available with electric gear motor with electronic variable speed control (115/230 VAC) 50/60 Hz electric gear motor or variable speed air gear motor (28 CFM@80psig/792.9 LPM @ 5.4 bar).
Model PQLM is the model for tough environments. This metal head version of the PQL lasts through long runs, numerous changeovers, and demanding applications. Variable speed control offers adjustable flows which can exceed 4 GPM.
Standard Graymills ink tanks are round to promote circulation and eliminate “dead spots” in corners where heavier materials can drop out and stagnate, causing viscosity and color issues. Tanks are available in 10, 20, or 30 gallon capacity and feature a built-in sump for low pump-down to reduce ink waste. A rolled rim at the top of each tank provides reinforcement while eliminating sharp edges. Removable sparkles casters are included. Tanks are available in 14 gauge epoxy coated mild steel or stainless steel.
Lids have overlapping rims to reduce evaporation and add strength. A hinged portion allows easy refilling or manual viscosity readings. Holes are provided for return hose and/or bypass. Large handles make lifting easy. Available in nickel plated mild steel or stainless steel.
Optional reusable or disposable tank liners are another way to speed up changeovers.
Take variables out of your printing process. Keep your color and viscosity more consistent with a full line of mixers from Graymills. These in-tank mixers keep inks properly blended, which is especially important for users of diaphragm or peristaltic pumps.
Small tank mixers fit 2 and 5 gallon containers. They are available with air motors. Can be mounted to optional lid. Also available to fit in 10, 20 and 30 gallon round tanks.
Mixers for 55 gallon drums are available side or lid mounted. These mixers use piston-powered air motors that run steadily at low RPM for gentler mixing, using less air and reducing noise. These mixers are designed to assure mixing throughout the container, even into corners, eliminating dead spots and changes in viscosity or color density. Most units are also available with traditional vane-style motors, which provide higher mixing speeds.
