The invention relates to a gear pump with two engaging gearwheels (9, 10) between a suction chamber and a pressure chamber, whereby the gearwheels are borne on bearing axles (11, 12) connected to the gearwheels. In accordance with the invention the gearwheels and the bearing axles are each manufactured of the same material as a homogenous workpiece. This allows simple construction of the gear pump with good operating properties at the same time. Preferably the gearwheels and bearing axles are made of synthetic material.
