A pump for conveying a medium comprises a pump chamber having an intake opening and an outlet opening. A movable component is movably disposed in the pump chamber in order to convey a batch of the medium, which is located in the pump chamber, from the intake opening to the outlet opening. A ventilation device has a ventilation opening in fluid communication with the pump chamber. The ventilation opening is different from the intake opening and the outlet opening. The ventilation device is configured to reduce or at least substantially prevent, at least temporarily, the formation of a partial vacuum or a negative pressure in the pump chamber.
