A diaphragm pump includes a pump housing having an inlet and an outlet for the fluid. The pump housing (2) includes a partition wall (4) which delimits two chambers (3) on a respective side of the partition wall. The two chambers are each closed by a respective diaphragm (9) connected to an electric coil (12) for causing the diaphragm to oscillate in coaction with a magnetic unit (14-16), therewith pumping the fluid.
