Abstract

A double-acting pump which includes two rooms that are each divided into an operating chamber (6) and a working chamber (5) by means of a moveable partition wall (4) in the form of a piston or a diaphragm (membrane), wherein each of said operating and working chambers is provided with a valve-controlled inlet and outlet (7, 9; 8, 9) for a gaseous drive medium or operating medium and a liquid working medium transported by the pump respectively, wherewith said partition walls lack all form of mechanical connection therebetween. An outlet conduit (23) includes a cavitation-gene-rating restriction (24). The pump can be operated in a manner such as to maintain cavitation in the restriction (24) when working medium passes through said outlet conduit.
