Abstract
A gear pump comprises a casing and gear rotors disposed therein. The gear rotors are lodged in bearing sections of plain bearings that are lubricated by the pumping medium. They have at least one cooling duct which is embodied such that cooling varies along the circumference and/or in the longitudinal direction and/or in the radial direction of the plain bearing.
