More About Graymills Products

We're proud to say that some of the products below have helped build some of the best presses in the world.

Centrifugal Pumps & Tank Systems Printing Press


Centrifugal Ink Pumps Centrifugal pumps are the workhorse of the industry. They are low maintenance, take a lot of abuse, deliver fluids in a non-pulsating flow, and provide in-tank circulation to keep material blended. Most Graymills centrifugal pumps feature “Tri-Rod” open columns, stainless steel rods and shaft, and Teflon™ coating for easy cleaning. These pumps are available with electric, electric explosion-proof, or air motors. Graymills offers a wide range of pumps and motors that comply with most international electrical and safety standards including CE, ATEX Ex, and UL. Quick Demountable (QD and QC) motor options on the H, M, and G series centrifugal pumps speed up press turnaround. Flow is easily controlled by the use of valves, or in the case of air motor models, by the flow of air to the motor.

Peristaltic Pumps for Printing Press

Peristaltic Ink PumpUnlike conventional peristaltic pumps adapted from other industries, Graymills peristaltic or “tube” pumps are engineered specifically for Flexographic and Gravure printing applications and have received U.S. Patent number 5,630,711. Graymills peristaltic pumps easily accommodate a wide variety of fluids form inks and coatings to adhesives – water, solvent, and UV/EB. These innovative design features are especially valuable in the pressroom when short runs require frequent changeover and quick turnaround. Built in the U.S. for reliability, low maintenance, and long life.

All Graymills peristaltic pumps feature a high output gear motor which combines variable speed and reversibility with essential torque. The steel pump housing, which protects the pump against splashing and damage, has a baked on hybrid powder coating for a long lasting durable finish. Three swivel lock fasteners quickly release the pump head cover, without tools or loose parts, facilitating a quick tube change. The Graymills head design allows the tube to run “straight-thru” from the bucket to the print deck, eliminating “pinch points” where kinks form that slow the flow and weaken the tube. Dual roller technology combines just two rollers with a longer compression cycle to provide greater flow with fewer rotations. This results in lower friction, reduced tube fatigue and less flow pulsation.

Superflo® Ink Filters & Surge Suppressors

Superflo® Ink FiltersGraymills Superflo® filters are specially designed for flexo 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.

Ink Mixers

Ink Pump MixersTake variables out of your printing process. Keep your color and viscosity more consistent with a full line of ink pump & tank 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.

Tank 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 industrial tank 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.

Tanks, Lids, & Liners

Disposable Tank LinersStandard 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.

megaMag™ Filter Magnets

Magnetic Ink FiltersFor Superior protection against anilox scoring/damage. A rare earth magnet in a smooth stainless steel casing, with 10x the pulling power of a standard magnet; megaMAG™ is able to attract metal particles from within the filter body or ink tank. Unlike other rare earth magnets, megaMAG’s domed end design with no crevices releases particles easily when cleaning.

megaMAG™ is available for use in Graymills Superflo® filters HFST and HFNT or on an adjustable bracket (C-37327 or mini-megaMag bracket C-38745) for placing inside a tank or pail. Also available for use in DDFSFST and DDPSFNT surge suppressor filters. Retrofits to all existing Superflo® filters and surge suppressors.

Dial-A-Flow™ Variable Speed Ink Pump Control

Ink Pump Control SystemDial-A-Flow™ Variable Speed Ink Pump Control makes press operation easier and improves print quality. Dial-A-Flow replaces unpredictable and time consuming valve settings in ink delivery systems. Using one simple dial on a small control box, it’s quick and easy to set the ink flow rate needed, freeing up operators for other tasks and achieving better, more consistent results. Available for most new/existing centrifugal ink pumps. Operates on 50/60 Hz., UL U.S./Canada listed. NOT FOR USE IN SOLVENT ENVIRONMENTS.
