Pump comprises a pump wheel (2) arranged in a pump housing (1) and positioned directly on a bearing pin without using a further bearing element. The material of the pump housing and the pump wheel has the same heat expansion coefficient. The pump wheel has a segment bearing (12) with a running diameter (13) interrupted by recesses (15) of the wheel in which a drive element of a drive shaft interacts.
