Diaphragm pump with electric vibrators

The invention relates, inter alia, a membrane pump (1) for delivering a preferably liquid and / or gaseous, conveying medium, having a movable conveyor diaphragm (40) and an actuator for the feed diaphragm (40) for moving the conveyor diaphragm (40) and a method for operating of the diaphragm pump (1). The diaphragm pump (1) is further developed in that the actuator as an electric vibration exciter (50) is formed, said electric vibrator (50) has an annular coil arrangement (2) and an annular gap (30) having the magnet arrangement (4), wherein said annular coil assembly (2) into the annular gap (30) of the magnet arrangement (4) engages in such a way that the coil arrangement (2) and the magnet arrangement (4) in an axial direction (X) are movable relative to each other, said coil arrangement (2 ) is operatively connected to the feed diaphragm (40) or connected.
