Isolated chamber pump with recirculation of leakages

A vibrating pump for displacement of liquids, the pump comprising:

• a hydraulic system consisting of a hydraulic head with an inlet and an outlet for liquid, said hydraulic head being joined by screws to an electromagnetic system composed of a metal frame which is mounted to a rear bolt and which is situated around a coil and a plurality of bushings so as to form a force chamber therein, wherein a magnetic core is positioned between two springs and moves in axial direction in a reciprocating motion, said magnetic core being coupled to a plunger disposed inside a compression chamber, the plunger extending through a leak recovery chamber, characterized in that:
• the leak recovery chamber, which is delimited by a pressure seal on one side and by a membrane on an opposite side, recovers any loss of liquid from the compression chamber and conducts it through a conduit directly to the inlet of the compression chamber, the inlet drawing in and re-infusing the liquid from the leak recovery chamber back into the compression chamber.
