MANUAL PUMP, characterized in that, it consists essentially of a glass bottle provided with a lid with a hole in its center through which a bushing is inserted that fixes the body to the lid; joining a body and a lid by means of two screws, being imprisoned between both pieces a plastic tank inside which slides a piston, provided with a rubber ring, by the manual pressure of a lever that pushes the axis of the piston, thereby triggering the opening of an outlet valve located at the end of an axis, and thereby ejecting the liquid, the piston retracting under a spring with which the opening of the inlet valve occurs, thereby allowing the admission of new liquid to the reservoir by means of the input shaft and leaving the apparatus ready for a new actuation.
