description The invention provides a pump with a pulsation suppression device which can further enhance the effect of suppressing pulsation. According to the invention, in one side portion of a pump head wall 1 having inflow and outflow passages 2 and 3, a first bellows 7 which is driven so as to extend and contract by an air cylinder portion 14, and check valves 16a and 16b which alternately open and close a pump working chamber 9a formed in the first bellows 7 are disposed to constitute a reciprocal pump portion 4. In the other side portion of the pump head wall 1, a pulsation suppressing portion 5 is configured so as to have a second bellows 18 that is extendable and contractible, and that forms: a liquid chamber 20a which can temporarily store liquid that is to be discharged from the pump portion 4; and an air chamber 20b which is isolated from the liquid chamber 20a. The pulsation suppressing portion absorbs pulsation of the liquid which is discharged from the pump portion 4, by a change in the capacity of the liquid chamber 20a. The extension rate of the second bellows 18 is set to be larger than that of the first bellows 7.
