Abstract

The present invention provides a pump comprising a housing (1), the housing comprises a first fluid section (2) and a second fluid section (3) separated by a reciprocating pump element (4), wherein the first fluid section (2) comprises an inlet/outlet (5) for a drive fluid; the second fluid section comprises an inlet (6) and an outlet (7) for a liquid, each of the inlet and the outlet comprises a one-way valve (8,9), such that a liquid may enter the second fluid section (3) via the inlet (6) and is forced to exit the second fluid section (3) via the outlet (7) during use; and the reciprocating pump element (4) is movable between a first position, wherein the volume of the first fluid section (2) is minimized and a second position, wherein the volume of the first fluid section (2) is maximized; wherein the pump comprises damping means (4,10,13) arranged such that the reciprocating pump element encounters an increased motion resistance when approaching the first and the second position, respectively, during use.
