The invention provides a device for the axial delivery of fluidal mediums, which outer diameter is not or only insignificantly larger than the diameter of the fluid carrying pipe, which reduces to a large extent a shearing and vortexing of the fluid. A device for the axial delivery of fluidal mediums, having a tubular hollow body arrangement, in which delivery area, an impeller (9) with a blading, which can be rotated, is arranged and also has a fluid directional means. A motor (2), at least one impeller (9) which can be rotated, and at least one motor mounting (14) are arranged in a tubular hollow body (1) of the hollow body arrangement. The impeller (9) is connected axially force-fittingly and/or form-fittingly to the motor (2).
