Abstract
A diaphragm pump (1) having two diaphragm heads (15), in each case two diaphragms (6) and two separate pump housings (3) in which the connecting rods (5) for the diaphragms (6) are arranged, which connecting rods (5) can be driven by a common shaft (4). The drive for the shaft (4) can be arranged between the two pump housings (3). Here, the two pump housings (3) are connected to one another in an air-permeable fashion in particular by a connecting line (7), such that the air displaced in each case by the one diaphragm (6) can be moved into the other pump housing (3) in which the associated diaphragm (6) leads to a space enlargement as a result of being driven in the opposite direction.
