Abstract
Gear pump with meshing gears enclosed by a pump housing, with bearing journals arranged on longitudinal axes and each projecting laterally away from the gears, wherein at least one of the bearing journals has, at least over part of its axial extension, a bearing journal diameter that lies in the range of 90% to 100% of a root diameter of the toothing of the associated gear. A toothing width (b) is at least twice the dimension of a distance (a) between the longitudinal axes, the toothing width (b) being an extension of the gears parallel to the longitudinal axes.
