  • Graymills Superflo® Ink Filters & Surge Suppressors

    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.

  • Graymills Ink Pump Mixers

    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.

  • Graymills MegaMag™ Filter Magnets

    For 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.

  • Graymills Double Diaphragm Ink Pumps

    For applications requiring controlled flow rates from a trickle to 40 gallons per minute. Especially suited to the requirements of bottom printing corrugated lines, where a single pump provides both supply and suction return.

    These pumps operate by the movement of two flexible diaphragms which move back and forth, alternately filling and emptying two chambers. Flow is controlled with the air inlet valve, which then determines pump speed. A variety of applications are possible because the pump’s inlets and outlets can be configured in different ways, such as “one-in one-out”, “1-to-1”, “two-in two-out”, or “2-to-2”. In the 1–to-1 option, one color is sent to the deck. In the “ 2-to-2” configuration, you can deliver one material and also draw it back, or deliver two inks to two different decks. Diaphragm pumps do have a pulsating flow and are best use with a Graymills surge suppressor/filter.

  • Graymills PPS Ink Pumps

    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).

  • Graymills PPL Ink Pumps

    For mid to wide web flexo, gravure, and rotary screen applications and light to heavy viscosity inks, coatings and adhesives (including UV/EB), requiring flow rates of 4.5 GPM or less. Available with electric gear motor with electronic variable speed control (115/230 VAC) 50/60 Hz or ATEX electric gear motor with variable speed control (230/460 VAC, 3 Ph) 50/60 Hz.

    Optional “Quick Change” removable head Model PQL. Pump head/tube changes are accomplished in seconds without tools. Simply pull the lock-pin, remove the used head, and replace with another head loaded with clean tube. PQL models include all of the features of the standard PPL models. “Quick Change” heads can be retrofit to Graymills peristaltic pumps made since January 2005.

  • Graymills Dual Head Pumps

    Two peristaltic pump heads powered by a single motor allow the pump’s heads to be individually set to supply or return. This ability, coupled with the pump’s variable speed capability and ability to reverse direction, allows for several pumping configurations:

    • Supply one ink to two separate decks
    • Supply two different  inks to two separate decks
    • Supply and return one ink to one deck

    These pumps are available in PPS or PPL versions, have standard quick change heads, eight position adjustable head orientations, and remote mounting of controls with a 16’4” (5m) cord. Available with electric gear motor with electronic variable speed control; consult factory for explosion proof model. CE compliant models available.  Optional hard coat anodized head with stainless steel rotors (PQL only).
