A delivery device for a single- or multiphase fluid having a tubular body for axially guiding the fluid, including a motor stator arranged outside the tubular body and a delivery element arranged within the tubular body, comprising a motor rotor. A rotor gap is formed between the delivery element and the hollow body for allowing the fluid to pass through. Mounting arrangements are fixedly disposed in axial direction on each side of the delivery element within the tubular body. Hub gaps are formed between the delivery element and the mounting arrangement. First permanent magnet bearing elements are disposed in the mounting arrangement and second permanent magnet bearing elements are disposed in the delivery element. The first and the second permanent magnet bearing elements functionally work together and are magnetized in axial direction and have opposite polarity. Position sensors associated with each of the first permanent magnet bearing elements and a stabilizer is disposed around the hollow body.
