Double acting piston pump, characterized in that inside the body of the pump and in opposite position there are two chambers connected to each other by two conduits that, in turn and towards their middle, are connected, the one with the suction pipe and the other with the impulsion pipe, the circulation of the liquid being found through said chambers and said conduits communicating them, governed by two sets of valves with opposite effects, located at the entrance and exit of each chamber, It is fortunate that the pumped liquid can not regress in its course from the suction mouth to the delivery mouth, and said circulation of the liquid is determined by an organ, endowed with a plunger in each of its extremities which, thanks to a movement of oscillating, penetrate, alternatively, in each of the aforementioned chambers producing, simultaneously, the discharge and impulsion of the contents of one of them and the vacuum and consequent aspiration on the other.
