Pumping system and fluid delivery installation

Pumping system for the delivery of a pressurized fluid, comprising:

• a drive chamber inside which is positioned a drive piston configured to slide therein along a longitudinal axis of a drive enclosure between first and second end positions under the effect of a pressurized operating fluid, the driving piston separating said drive enclosure into a first driving chamber and a second driving chamber,
• a first multiplier chamber and a second multiplier chamber comprising an inlet and an outlet for, respectively, receiving and discharging a delivery fluid,
• a first multiplier piston, connected to the driving piston and configured to slide within the first multiplier chamber, the sliding of the first multiplier piston ensuring the compression of the delivery fluid inside the first multiplier chamber such that the pressure of the delivery fluid at the outlet is greater than the pressure of the delivery fluid at the inlet of the first multiplier chamber,
• a second multiplier piston, connected to the drive piston and configured to slide within the second multiplier chamber, the sliding of the second multiplier piston ensuring the compression of the delivery fluid inside the second multiplier chamber such that the pressure of the delivery fluid at the outlet is greater than pressure at the inlet of the second multiplier chamber,
• an alternating fluid distribution device for alternating the direction of circulation of the operating fluid in the drive enclosure,
• the pumping system comprising a first fluid inlet opening into the first drive chamber and a first fluid outlet from the second drive chamber for, respectively, receiving and discharging the operating fluid during a first distribution cycle, and that it comprises a second fluid inlet opening into the second drive chamber and a second fluid outlet from the first drive chamber, for, respectively, receiving and discharging the operating fluid during a second distribution cycle, and in that the alternating distribution device comprises at least one shutting-off device comprising four movable shutting-off members of the first and second inlets and first and second outlets of the pumping system and at least one trigger configured to actuate said shutting-off members between two respectively shutting-off and open positions, said alternating distribution device can be actuated between:
• a first arrangement associated with the first distribution cycle in which the drive piston moves to its second end position, two of the movable members respectively shut off the second inlet and the second fluid outlet, and the other two movable members respectively open the first inlet and the first fluid outlet to ensure the insertion and discharge of the operating fluid, and a second arrangement associated with the second distribution cycle in which the drive piston moves to its first end position, two of the movable members respectively shut off the first inlet and the first outlet, and the other two movable members respectively open the second inlet and the second outlet to ensure the insertion and discharge of the operating fluid,
• wherein the alternating distribution device comprises:
• a first activation member configured to simultaneously actuate the knife gate valves of the first and second fluid inlets arranged on the same side of the drive enclosure, said valves being interconnected longitudinally such that the driving of one of the valves towards one of its shutting-off or open positions drives the other valve in the opposite position, and
• a second activating member configured to actuate the knife gate valves of the first and second fluid outlets arranged on a same side of the driving enclosure, said valves being interconnected longitudinally such that the driving of one of the valves towards one of its shutting-off or open positions drives the other valve in the opposite position.
