Disclosed is a pump (5) that has an electric motor (4) and is used to deliver a fluid, in particular in a motor vehicle. Said pump comprises at least one impeller (18) that has delivering elements (19) and can rotate about an axis of rotation (27), a working chamber on the at least one impeller (18), an electric motor (4) including a stator (13) and a rotor (16), a housing (8) that has an intake port (29) for feeding the fluid to be delivered into the working chamber (47) and a pressure port (30) for discharging the fluid to be delivered from the working chamber. The at least one impeller (18) including the delivering elements (19) as well as the electric motor (4) are arranged inside the housing (8), and the stator (13) is at least partly, in particular entirely, sealed by a sealing sleeve which forms a plain bearing unit for the at least one impeller (18), at least one impeller (18) being mounted on the plain bearing unit of the sealing sleeve. The stator (13) has one or more openings that are filled by the sealing sleeve, the plain bearing unit having a depression on each of the one or more openings. |
