An electrically driven diaphragm suction or pressure pump includes an oscillating anchor magnet that serves as the driving motor. The oscillating anchor magnet has a magnet coil (16), which is concentrically enclosed by a ferromagnetic closing cage (19) which is discontinuous in a circumferential direction. In the interior space of the magnet coil (16), the closing cage forms two pole rings (25,26), separated from one another in the axial direction by a circular slot (27). The closing cage is tightly arranged in a case (28,29). To obtain a high efficiency and high pump capacities, the central anchor shank (39), which is connected to the pump diaphragm, of the oscillating anchor (8), which is provided with a ferromagnetic solenoid plunger (38), is attached to two leaf-type vibratory springs (42, 43), each of which carries and centers on one side an end section projecting out of the closing cage (19) of the magnet coil (16). Both of these vibratory springs are shaped the same and attached, at an axial distance from the closing cage (19), with their respective base sections (48) to contact surfaces (61, 62) of the case (28, 29), which are arranged diametrically opposite on different sides of the system axis (9) and at equal distance from this system axis (9).
