Graymills advanced centrifugal pumps are engineered to meet the delviery requirements of both solvent and water-based inks and coatings. Our combination of quality features is evident inside and out and is unmatched by any other ink pump manufacturer.

Our pumps feature:

• Agitor(R) feature to keep solids in suspension, helping to maintain viscosity
• Tri-Rod construction, with the open column design eliminating hard-to-clean ink build-up common to solid column pump designs
• Teflon(R) coating for easier clean up
• Stainless Steel shaft, coupling and Tri-Rods
• Celcon(R) impeller bringing less weight, pump wear and longer service life.

Our Centrifugal pumps are available in multiple lengths, US and metric threads available.

Graymills Double Diaphragm Pump inlet and outles can be configured to meet the pumping requirements from bottom-printing corrugated lines to flexo and gravure presses. A variety of corrosion resistant materials permits use with water, alcohol, and solvent-based inks and coatings. Our unique "slide valve" design prevents stalling even when running at low speeds. Our pumps are designed for easy maintenance with a minimal number of parts.

A variety of applications are possible because the pump's inlets and outlets can be configured ion different ways, such as "one-in, one-out" or "two-in, two-out". In the 1-to-1, 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.

These motor options are available with Graymills pumps and ink circulating systems. This variety of choices lets you configure your system to meet specific printing and press requirements, whether water, solvent-based or UV.

Removes heavy contamination. Developed for use in corrugated and tissue plants, 10 mesh (2000 micron) stainless steel basket fits inside standard U.S. 5 gallon pails. Return hose from fountain drains into strainer where heavy contaminants are trapped.

Graymills international award winning "Quick Change" peristaltic ink pumps are available in single and dual head versions. These pumps, developed specifically for printers, allow users to change hose and pump heads in seconds. Our Patented Head Design allows the tube to run direct from the ink container to the print deck -- eliminating tube-destroying kinks, flow stoppages, snaking or tube creep common in other peristaltic pump designs. We are constantly working with printers to develop new features to better serve their needs. We'll be displaying our Metal Head Peristaltic at Drupa.

Graymills standard ink tanks are round to promote circulation and elminate "dead spots" in corners where heavier materials can drop out and stagnate, causing viscosity and color issues. Round tanks of 10, 20, or 30 gallon (37.9, 75.7, 123.6 liter) capacities 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 elimiating sharp edges. Removable sparkless casters are also featured for added safety. Tanks are available in either 14 gauge epoxy coated mild steel or stainless steel. Lids are available in nickel plated or stainless steel.

Lids have overlapping rims to reduce evaporation and add strength. A hinged portion allows easy refilling or taking of manual viscosity readings. Holes are provided for reutrn hose and/or bypass. Large handles make lifting easy.

Optional reusable or throw-away tank liners are another way to speed up changeovers.

Graymills also manufactures custom and OEM tanks and lids. Please discuss your needs with our representatives.
