Abstract

The invention relates to a pump arrangement for liquids, which comprises at least one pair of cooperating pump chambers (1, 2), to and from which the pumped liquid flows in and out alternately governed by a pneumatic control system. The object of the invention is to suppress pulsations in the outgoing flow. For that purpose the arrangement is designed so that the suction and pressure strokes in each of the pump chambers occur independently of the suction and pressure strokes in the other pump chamber. In this way an active compression pressure does always reside in at least one of the control chambers of the control system so that a drive pressure is continuously maintained in the outlet line (11) from the pump arrangement.
