Improvements in pressure pumps for lubrication, characterized by the arrangement in the piston of the pump of an internal groove toward the upper end similar to a sebera with holes or ducts made in the face in axial direction, communicating with the previous slot so that all this constitutes steps diverted to the grease or pumped oil, said piston being a solid body with a circular central groove in which a rubber ring is placed stoped that makes a perfect closing on the walls of the cylinder.
