Zusammenfassung:	A fusion pump for transmitting the colophony with high viscosity belongs to infusion pump field, comprising an end cover and a gear shaft, which drills through a bore of the end cover. A filler, a side of which is provided with a gland, is arranged between the gear shaft and the end cover. The utility model is characterized in that a sealing ring, which is in clearance fit with the gear shaft, is positioned between the gear shaft and the end cover at the other side of the filler. For adopting the composite sealing mode of combining the filler and the sealing ring, the utility model has great sealing performance, food continuous operation state of the pump, low cost and convenient installation.
