Gear pump with intermeshing gear wheels enclosed by a housing with bearing journals arranged on shaft axes, each projecting laterally from the gear wheels, which are mounted in the housing by means of slide bearings, having a slide bearing length, the slide bearings being lubricated with pumped medium. The invention is characterized in that a filling pocket with radial expansion is incorporated in each of the slide bearings in the region of a pump pressure side, the filling pocket being spaced from a gear-side end face of the respective slide bearing by a distance, so that a bar with a bar width with axial expansion corresponding to a slide bearing surface is formed, and in that a lubrication groove with a tampering cross-section is provided in each of the slide bearings, the lubricating groove starting from an end on the gearwheel side towards a slide bearing end and starting at the filling pocket on the gearwheel side and communicating therewith.
