A feed pump designed as a side-channel or peripheral pump has two rings of guide vanes arranged in an impeller and concentrically enclosing one another. The sides of the guide vanes facing the intended direction of rotation of the impeller are inclined at an angle relative to the axis of rotation of the impeller. The angles of the guide vanes in a radially outer ring of guide vanes are larger than the angles of guide vanes in a radially inner ring of guide vanes. This arrangement allows the impeller to be produced in an injection mold in an especially cost-effective manner.
