Beschreibung
Zusammenfassung:	Provided is a bellows pump device that is able to reduce fall of a discharge pressure of a transport fluid during contraction operation of a bellows. The bellows pump device (BP) supplies pressurized air to a hermetic discharge-side air chamber (21) thereby to cause a bellows (13, 14) disposed within the discharge-side air chamber (21) to perform contraction operation to discharge a transport fluid, and discharges the pressurized air from the discharge-side air chamber (21) thereby to cause the bellows (13, 14) to perform expansion operation to suck the transport fluid. The bellows pump device (BP) comprises an electropneumatic regulator (51, 52) configured to adjust an air pressure of the pressurized air to be supplied to the discharge-side air chamber (21), such that the air pressure is increased so as to correspond to a contraction characteristic of the bellows (13, 14) during the contraction operation of the bellows (13, 14).
