A liquid pump for conveying a liquid may include a housing, in which a pump impeller is arranged for conveying the liquid, and a cover for covering the housing. The cover may include a main connector for supplying a main flow of the liquid to the pump impeller and an auxiliary connector for supplying an auxiliary flow of the liquid to the pump impeller. The housing may have an inlet opening for the liquid and an annular collar protruding from an edge of the inlet opening. The cover may lie axially against the annular collar. The annular collar and the cover may define an annular wall surrounding a flow path of the main flow of the liquid. The annular wall may have at least one radial opening connecting the flow path with an inflow space surrounding the annular wall. The auxiliary connector may be fluidically connected with the inflow space.
