Abstract: A portable ink pumping system for supplying ink to an ink fountain includes a cart, a container, a progressive cavity pump, and an ink fountain mounting bar. The ink fountain mounting bar is designed to be releasably connected to the ink fountain of a printing station. The ink fountain mounting bar includes a proximity sensor, a control box, and at least two ink dispensing nozzles. The proximity sensor monitors the level of the ink in the ink fountain while the control boy controls the level of the ink. The material of the nozzles and associated fittings and tubing allows for quick and thorough cleaning of any remaining ink when an ink change is required. Moreover, when a radical ink color change is required, the nozzles, fittings, and tubing can be removed and replaced with new components.

Abstract: The present invention relates to a gear pump or the like able to effectively prevent excess heat generation between a gear shaft and a journal bearing. A gear pump (1) that lubricates gear shafts (14, 15) on which gears (12, 13) are attached and journal bearings (62, 63) that rotatably support the gear shafts (14, 15) with an ultraviolet-curable ink that is a transport target, in which a width diameter ratio that is a ratio of a bearing length of the journal bearings (62, 63) to the shaft diameter of the gear shafts (14, 15) is 0.5 to 2.0, and a clearance ratio that is a ratio of a radial clearance between the gear shafts (14, 15) and the journal bearings (62, 63) to the shaft radius of the gear shafts (14, 15) is 0.0009 to 0.01.

Abstract: To reduce frictional heat generated between a rotation shaft and a bearing portion in a gear pump in which the rotation shaft having a gear mounted thereon is received by the bearing portion and an image recording apparatus having the gear pump. Provided is a gear pump which has a rotation shaft, a bearing portion which receives the rotation shaft, and a gear which is mounted on the rotation shaft and rotates with the rotation shaft, in such a manner that the gear feeds liquid. Furthermore, at least either a concave portion or a convex portion is provided in at least either the rotation shaft or the bearing portion.
