Abstract (en)
The pump (1) has two membranes (19,20) with curvatures facing towards or away from each other with their outer edges fixed in the pump housing (11) and their inner edge regions clamped to displaceable piston rods. Two reaction chambers (27,28) formed between the membranes and a cylinder holding the piston (22) are filled with hydraulic medium and are connected by a hydraulic rod.
