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).
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.
Optional “Quick Change” removable head Model PQS. 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. PQS models include all of the features of the standard PPS models. “Quick Change” heads can be retrofit to Graymills peristaltic pumps made since January 2005.
