Improvements in the piston pumps for fluids, characterized by providing a mechanical link between the intermediate membrane for separating the fluid to be compressed and the active piston of the alternative train, which allows the existence of a free play between said piston and the membrane, existing a connecting rod of said membrane with the main piston that is endowed with an end head that slides inside an existing housing in the crown of the plunger allowing the longitudinal sliding of the shank, which is limited at the end of its travel by a top stop existing in said plunger housing and the stem itself being connected at the other end to the intermediate membrane.
