Abstract: An external gear pump, having a driving first pump gear and a second pump gear driven by the first pump gear, which intermesh to convey a fluid from a suction side to a pressure side of the external gear pump. The first pump gear and the second pump gear each have a plurality of teeth, each having a leading tooth flank leading in the rotation direction of the corresponding pump gear and a trailing tooth flank. The leading tooth flank of the first pump gear interacts with the trailing tooth flank of the second pump gear to drive the second pump gear via the first pump gear. The trailing tooth flanks of the first pump gear extend concavely to form a fluid pocket at at least one axial position in the radial direction at least in sections in each case.
