Grease pump, of the type comprising a reservoir containing the lubricant, on which a telescopically assembled nozzle is mounted that drives the lubricant drive-ejector mechanism, essentially characterized by the fact that the reservoir has a cylinder attached to it inside a coaxial rod with radial fins resting on a seat of the mouth of the reservoir and pressed by the end of the cylinder itself is fixed, the rod of which can be sealed tightly inside a tubular piston slideable inside the cylinder, integral with a tubular outlet nozzle of the lubricant and pushed by a spring that tends to keep it away from the tank, whose piston is provided with a valve that tends to remain closed in the opposite direction to the outlet of the lubricant.
