The invention relates to a pump unit, in particular a wet-rotor pump for a heating or drinking water system, said unit comprising a pump housing which delimits a pump chamber, an electric motor and a shaft (20) which bears the rotor of the electric motor, said shaft being supported by at least one canned bearing unit (1), through which the shaft (20) extends. The bearing unit (1) is injection moulded in one piece from plastic and is formed by a plain bearing (3) and a bearing carrier (2). The bearing unit (1) has an inner region that forms the plain bearing (3) and supports the shaft (20) and an outer region that is held in the can and forms the bearing carrier (2). In addition, the bearing unit (1) is completely produced from a tribologically active plastic, or only the inner region which forms the plain bearing (3) is a layer (8) or coating of the bearing carrier (2) consisting of a tribologically active material.
