The automated pumping sytem will reduce double-doctoring and end seal failure by reducing internal cavity pressure. The internal cavity pressure is reduced using a diaphram pump to evacuate the cavity.
The station consists of two diaphram pumps built in one enclosure, one pump sends ink to the the cavity, and the other discharges ink . Witha turn of a switch, the automated pumping system allows the operator to clean up the anilox roller and cavity from the control panel located on the press. All inlet and outlet fittings are located on the exterior of the cabinet. Banjo quick release fittings allow for rapid changing and cleaning of the feed and return lines.
A simple control panel is located on the face of the enclosure to allow setting of the feed and retun rate of the ink or coating material. The flow is adjusted by a regulator and repeat settings can be achieved by recording the pressure gage settings. The pump is available in manual or automatic models and can be double stacked for multiple color management.
