Abstract

In connection with a flow pump, particularly for the conveying of fuel from a fuel tank of a motor vehicle, with a pump chamber (16), an impeller wheel (24) rotating in the pump chamber (16), and two parallel side walls (17, 18) spaced apart from each other and delimiting the pump chamber (16), in one of which a groove-like side channel (26), open toward the pump chamber (16), is disposed, which extends concentrically to the pump axis from a channel start (261) to a channel end (262), a further pump inlet (30) for the connection of a fluid return line (13) and which opens directly into the side channel (26) at a distance from the channel end (262), is provided for the purpose of improved efficiency of the flow pump.
