he design of the pump takes full account of the lubrication of the bearing and the wear resistance of the parts in the work. The separation of the bearing and the pump chamber-external lubrication structure is adopted, which changes the traditional structure of the original gear pump lubricating the bearing with the conveying medium and ensures the transmission accuracy of the main components. The conveying temperature of the pump is generally 20 - 180 C, and the special structure can reach 250 C.
