A diaphragm pump, comprising - a carrier part, a drive motor which is arranged thereon and which has a drive shaft which rotates about a main axis of rotation, - a pump head (4, 4') with at least one pump chamber (8, 8') which is delimited by a diaphragm (7, 7') driven in oscillation, and - an inlet port and outlet port, which are arranged on the carrier part and which are each able to be alternately connected via a shuttle valve arrangement (12, 12') to the at least one pump chamber (8, 8') in the sense of an intake stroke and exhaust stroke, characterized in that - the pump head (4, 4') is mounted rotatably in the carrier part and is connected to the drive shaft in an orientation such that the direction of oscillation of the diaphragm (7, 7') is directed orthogonally with respect to the main axis of rotation of the drive shaft, - there is provided for the diaphragm (7, 7') a drive transmission element (13, 13'), which = firstly is mounted on the pump head (4, 4') so as to be displaceable in the direction of oscillation of the diaphragm (7, 7') and is connected to the diaphragm (7, 7') in terms of drive kinematics by way of a coupling element (21, 21'), and = is guided in a bearing disk, which is mounted so as to be rotatable eccentrically with respect to the main axis of rotation, so as to be displaceable orthogonally with respect to the direction of oscillation of the diaphragm (7, 7'), such that, = owing to the eccentricity-induced displacements of the drive transmission element (13, 13') relative to the pump head (4, 4') and to the bearing disk, the drive transmission element (13, 13') generates, by way of its coupling element (21, 21'), the oscillatory movement of the diaphragm (7, 7') in the pump chamber (8, 8') during the rotation of the pump head (4, 4'), brought about by the drive shaft, and the rotational driving along of the drive transmission element (13, 13') by the pump head (4, 4'), and, - as a result of the rotation of the pump head (4, 4'), a pump medium line arranged therein is alternately connected to the outlet port and the inlet port. - a carrier part, a drive motor which is arranged thereon and which has a drive shaft which rotates about a main axis of rotation, -
