Abstract
A coolant pump is provided that includes a pump housing that receives a pump shaft for driving a pump member for a liquid medium in a medium chamber. The pump shaft is arranged at least in sections in the medium chamber and is rotatable mounted by means of an anti-friction bearing. The anti-friction bearing has a plurality of rolling bodies which are arranged in a rolling body chamber. The rolling body chamber and the medium chamber are fluidly connected, such that the anti-friction bearing device is lubricated and/or can be lubricated with the medium from the medium chamber.
