Abstract
A pump for conveying a pump fluid, wherein the pump fluid provided at an inlet pressure at a low pressure side of the pump can be conveyed in the operating state to a high pressure side of the pump rotor by means of a pump rotor rotatably supported about an axis of rotation in a pump stator and wherein a rotor shaft is arranged with the pump rotor at it drive bearing formed as a shaft bearing, characterized in that a lubricating film which is formed from a lubricating fluid formed from the pump fluid can be formed on a drive side of the rotor shaft between the rotor shaft and a drive bearing in a lubricating ring gap, with a lubricant line being provided such that the lubricating fluid can be supplied to the lubricating ring gap between the rotor shaft and the drive bearing.
