ABSTRACT:
A pumping device providing direct energy exchange between a working fluid and a pumped fluid, comprising at least a first ejector propelling the working fluid in one direction and at least a second ejector propelling working fluid in a second direction. The axial thrust induced by the jet emitted in the first direction compensates at least partly that of a jet emitted in the second direction.
