A method and a lubricant dosing pump for accurately dosing the small lubricant quantities. It is provided that at least two pistons are moved from an initial position relative to one another, thereby enlarging a dosing volume situated between them, and that thereby lubricant is conveyed through an inlet into the closing volume. Subsequently, the inlet is sealed and the two pistons situated opposite to each other in the stroke direction are moved together with the dosing volume until in a discharge position the dosing volume is connected with a discharge opening spaced apart from the inlet in the stroke direction. Then, the pistons are moved relative to each other, thereby reducing the dosing volume, and convey a predetermined dosing quantity of the lubricant through the discharge opening. Finally, the pistons are moved back into their initial positions.
