Abstract
A coolant pump () of an internal combustion engine, having a pump casing (), in which a pump shaft () is rotatably supported by a water pump bearing assembly () and an impeller () connected in a rotationally fixed manner to the pump shaft () is associated with an intake space (). During a rotation of the impeller () together with associated blades (), a coolant as a working medium is pumped from the intake space (), via a coolant outlet of the coolant pump (), into a cooling system of the internal combustion engine. A dirt trap is associated as a functional module () with the impeller () on a side facing away from the intake space (), wherein the working medium flows into the functional module () from the intake space via at least one opening () introduced into the impeller and emerges via a flow outlet ().
