A pump assembly comprising at least one housing and two gear wheels. The housing comprises at least one base plate and a cover element, which are interconnectable to form a pressure chamber. An outer circumferential surface of each of the two gear wheels has a toothing, and the gear wheels intermesh via the toothings to convey a fluid. The gear wheels are arranged along an axial direction in the pressure chamber between the base plate and the cover element. The pressure chamber is formed in the housing at least by two bores. The first gear wheel is arranged in a first bore and the second gear wheel is arranged in a second bore. Centering pins are provided for aligning the bores and the gear wheels with respect to one another, wherein all centering pins are arranged exclusively in the cover element or exclusively in the base plate.

Pump assembly and method for producing a pump assembly

The invention pertains to a plain porous bearing for motors and transmissions with a circular bearing bore that displays, distributed alternatingly across the bearing bore, highly compressed at least approximately closed-pore areas and slightly compressed, open-pore areas, where the bearing bore diameters of the highly and slightly compressed areas are at least approximately identical. Also provided is a procedure and device for production of the bearing.
