A pump body for a medical gear pump for sucking and irrigating has a pot-like pump housing with two cylindrical openings, in which two meshing gearwheels are embedded. The driving gearwheel is, without pivot bearing, embedded in the opening. A lid is used for closing the pot-like pump housing. A trunnion protrudes from a bottom of the pump housing, onto which trunnion the driven gearwheel is mounted.
