Summary:The invention relates to a pump (1) for dispensing a fluid, comprising a pump head (2), a piston body (15) with a piston, which can be moved by a corresponding movement of the pump head (2) between an upper starting position and a lower end position, a pump chamber (13) defined by a pump chamber body (14), an inlet valve (12) and an outlet valve (16), a return stroke force for a return stroke from the lower end position to the upper start position is provided by bellows (18), in which further two bellows, a first bellows and a second bellows, are arranged one above the other, and when the pump head (2) is moved to the lower end position by exerting a compressive force on the pump head (2), the return stroke force is applied to the return stroke from the lower end position to the upper start position. Each bellows (18) is folded, the first bellows being subjected to compressive forces by direct engagement with the pump head (2) and the second bellows being subjected to compressive forces only by engagement wit
