Zusammenfassung:The invention relates to a supercritical carbon dioxide waterless dyeing circulating pump which comprises an external sealing mechanism, a rotating assembly arranged in the external sealing mechanism, a rotating piece arranged outside the external sealing mechanism and a power device mechanism. The power device mechanism is fixedly connected to one end of the external sealing mechanism; the rotating part outside the external sealing mechanism is positioned between the external sealing mechanism and the power device mechanism; a power device in the power device mechanism drives a rotating piece outside the external sealing mechanism to rotate; the pump has the advantages of no leakage, simple structure, low processing precision requirement, convenience in flow regulation, stability in working and the like; the ceramic ball bearing is adopted as the bearing in the pump body, and compared with a sliding bearing, the friction area is small, the friction loss is small, and the transmission efficiency is high; the
