Zusammenfassung:The invention relates to a positive displacement pump (100) comprising a drive unit (1) and a pump unit (2) having several working chambers (4 4 ) several displacement elements (3 3 ) and at least three cylinders (5) preferably exactly three cylinders (5) wherein the pump unit (2) is double acting. The invention further relates to a piston diaphragm pump forming a positive displacement pump wherein a diaphragm stroke is caused by means of working liquid present on the first side of a diaphragm and a medium to be pumped is conducted through a diaphragm chamber bounded by the second side of the diaphragm due to the diaphragm stroke and the diaphragm stroke is caused at a diaphragm position different from a vertical position of the diaphragm.
