Centrifugal Ink Pumps

Centrifugal Ink Pumps

greymills pump inkThis industry workhorse is low maintenance, takes a lot of abuse, and delivers ink in a non-pulsating flow. Graymills centrifugal models provide in-tank circulation to keep the material in the tank blended. Available with electric or air motors, with a Quick Demountable motor option. 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.

Double Diaphragm Ink Pumps

Double Diaphragm Pump Ink

double diaphragm pump ink

These air driven pumps operate by the movement of two flexible diaphragms that move back-and-forth, alternately filling and emptying two chambers. As each chamber is emptied, the ink is pushed toward the print deck. A variety of applications are possible, because the inlets and outlets can be configured in different ways. Good for corrugated bottom printers. Pump function produces a pulsating flow, so Graymills surge suppressor filters are strongly recommended.
