摘要： A magnetic levitation centrifugal pump comprises: an internally hollow body, an inlet connector and an outlet connector for blood. The hollow body comprises a lower element and an upper element which are mutually coupled to each other; a rotor element housed inside the hollow body and provided with a portion made of magnetic material, the rotor element being magnetically commanded in rotation about a relative axis, without contact, by a stator element associable with the hollow body. The upper element has a perimeter flange for coupling and a substantially dome-shaped body projecting from the perimeter flange. The outlet connector is associated with the dome-shaped body and is spaced away from the perimeter flange, between the outlet connector and the perimeter flange being defined an air space inside which mutual tightening device/component can be inserted for the tightening of the upper element with the lower element.
