Pump for hydraulic operation, essentially characterized by having inside its cylindrical body a sliding piston that extends into a tail of smaller diameter, which protrudes to the outside through the appropriate step provided for this purpose in the removable lid that closes one of the ends of the pump body, said piston having an axial passage that passes through it and in which a cylindrical bar is housed which constitutes a second plunger, sliding in the first, from which it protrudes through said glue in a sufficient length to allow assembly without interference of the parts responsible for the coupling to the drive devices that drive in their alternative movement to the aforementioned bar.
