Abstract
A gear pump has two engaging gearwheels disposed between a suction chamber and a pressure chamber, with the gearwheels borne on bearing axles that are connected to the gearwheels. The gearwheels and the bearing axles are each manufactured of the same material as a homogenous workpiece. This provides for both simple construction of the gear pump and good pump operating properties. Preferably the gearwheels and bearing axles are made of a synthetic material.
