The system has a positive displacement pump (20) located in a tank (14) and is activated by a control component located outside the tank. The pump delivers fluid medium (13) or gaseous medium from the tank to the user equipment. The pump is formed as a diaphragm pump with two chambers, with one chamber (23) connected to the control component, and the other chamber (32) for sucking medium out of the tank and delivering it to the user equipment.
