The invention relates to a magnetic coupling pump, with the motor-driven part of the magnetic coupling lying radially inward and the radially outward part of the coupling, together with the pump rotor, having a floating fit in the pumped fluid such that the rotating part of the floating bearing is also radially arranged over the outer magnets. The wall of the pump housing can itself be embodied as the stationary part of the floating bearing with the possibility of direct external access (lubrication, sensor mechanism) and an effective convectional cooling. Dry running on operational faults can be avoided by means of the floating bearing arranged far to the outside, as the damaging gas fraction collects in the radial interior of the pump and remaining traces of liquid are continuously driven outwards and thus contribute to bearing lubrication. By means of an additional annular barrier, the loss of residual fluid can be prevented. The disclosed novel floating bearing permits a large volume separating case which itself permits components of the roller bearings of the motor-driven magnetic coupling section so much installation space that the axial installation length of the complete pump can be significantly shortened.

People who wear a prosthesis currently have to use a bathing prosthesis if they wish to pursue water sports or take a shower or reach a body of water for recreational purposes and take active part in beach pursuits safely. However, these are usually taken off for swimming though this is very often not possible in the case of rocky shores or unsupervised beaches, quite apart from the unwelcome attention to which the person wearing the prosthesis is sometimes exposed in doing so. To solve this problem, a protective device for use for exterior prostheses is suggested, in which the protective device is a protective covering made from an at least semi-elastic, durable and damage resistant material being watertight or custom-designed sufficiently preventing a penetration of water into the inside of the protective covering and being dimensionally conformed to the shape of the body, and at least one end of which is furnished with a cuff or sleeve or collar like semi-elastic device that is dimensionally adapted to the contours of the anatomy of the person wearing the protective covering to prevent water or moisture or foreign bodies from penetrating the protective covering. This is particularly convenient and easy to carry and use when travelling and for recreational sport.
