Abstract

A pump diaphragm 5, e.g. for feeding a filter press, is reciprocated by a liquid column acted upon by a piston 35 reciprocated by a hydraulic motor 1 which is depressurised when a predetermined delivery pressure is reached. The volume of the liquid column is maintained by a control system incorporating a diaphragm sensor 51, 52. <IMAGE>
