ABSTRACT:
A system for handling two liquid streams comprises an hydraulic circuit including a pair of receptacles each provided with movable partition means dividing it into first and second chambers. Rod means extending through a first chamber of each receptacle connects the partition means and is effective to cause reciprocation of one partition means to be repeated by the other so that as the first chamber of one receptacle is expanded, the first chamber of the other receptacle is contracted. A quantity of the first liquid is delivered alternately to the first and second chambers of one receptacle as those chambers expand. As those chambers contract first liquid is passed through conduit means from the first and second chambers of said one receptacle to the first and second chambers, respectively, of said other receptacle. A source of second liquid is connected to said conduit means and liquid removal means is connected to said circuit to remove liquid from said circuit in quantities equal to the quantity of second liquid admitted to the circuit.
