The Smarter Ink Pump Family is the company’s newest innovation in peristaltic pumps. Smarter Pumps have a new physical appearance and smaller footprint than previous Graymills models and can be mounted vertically or horizontally and easily adjusted in the field. They feature Graymills’ proven quick-disconnect removable head technology, which allows the pump head/tube changes to be accomplished in seconds without tools.
Four distinguishing features of the new pumps are a display that indicates rotational speed, a predictive hose failure monitor, one-button reverse drain shutdown sequence with an adjustable timer and remote analog control with available digital connectivity.
According to Kristen Shields, president of Graymills, “I’m pleased that we will launch this new pump family at Labelexpo Europe 2019. This year we are celebrating our 80th anniversary with the tagline ‘After 80 years, we’ve got innovation down to a science.’ The Smarter Pump family is a clear example of our commitment to working with press builders, converters and ink makers to develop innovative ink circulating and conditioning systems that meet their unique requirements.”
Unlike conventional peristaltic pumps adapted from other industries, all Graymills peristaltic or “tube” pumps are engineered specifically for flexo and gravure printing applications and can easily accommodate a wide variety of fluids from inks and coatings to adhesives including water-based, solvent-based and UV/EB.
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.
