A bellows pump device includes: a first electropneumatic regulator 51 that adjusts a first air pressure of pressurized air in a first discharge-side air chamber 21A of a first air cylinder unit 27; asecond electropneumatic regulator 52 that adjusts a second air pressure of pressurized air in a second discharge-side air chamber 21B of a second air cylinder unit 28; and a control unit 6 that controls the first electropneumatic regulator 51 such that the first air pressure is continuously decreased during a period from a time when a second bellows 14 starts contracting until a first bellows 13 comes into a most contracted state, and controls the second electropneumatic regulator 52 such that the second air pressure is continuously decreased during a period from a time when the first bellows13 starts contracting until the second bellows 14 comes into a most contracted state. 波纹管泵装置具有：第1电动气动调节器(51)，其对第1气缸部(27)的第1排出侧空气室(21A)中的加压空气的第1空气压力进行调整；第2电动气动调节器(52)，其对第2气缸部(28)的第2排出侧空气室(21B)中的加压空气的第2空气压力进行调整；以及控制部(6)，其在从第2波纹管
