Zusammenfassung:	The invention relates to a hydro-pneumatic pumping installation. The pumping installation comprises two double-acting hydro-pneumatic boosters 2, 3. The pneumatic cylinder 4 and 14, respectively, of the boosters 2, 3 is arranged to contain a piston 7, and 17, respectively, arranged to divide the cylinder into two pneumatic chambers 10, 11 and 20, 21, respectively, and a second piston 8, and 18, respectively, arranged to divide one 11 and 21, respectively, of its pneumatic chambers into two parts 12, 13 and 22, 23, respectively, which are intended for being connected alternately to the atmosphere, and are connected to corresponding controlling chambers 39d, 39e, 40d, 40e of the distributor 39 and 40, respectively, of the second booster 2, 3.
