The invention concerns a washing fluid pump (1) for windows and/or headlamp cleaning installations on motor vehicles including at least one motor, at least one pump housing (2) with at least one impeller (11) arranged therein, at least one intake (8) and at least two selectively actuable outlets (7). The washing fluid pump (1) is distinguished in that the pump housing (2) includes at least two pump chamber regions which are arranged in mutually superposed relationship, that at least two outlets (7) are associated with different pump chamber regions, and the impeller (11) is axially displaceably supported in the pump housing (2) in such a way that it can assume its operative position selectively in one pump chamber region or the other.
