Abstract

A delivery pump for fluids is disclosed comprising: a pump body (3) connected to a container (C); a first piston (5) having a second cylindrical wall (52) and an annular lip (53) protruding therefrom; a second hollow piston (7) coaxial to the first piston (5) and having a bottom member (6) provided with annular grooves (62, 63) co-operating with the first piston (5) to define sealing zones; elastic means (16) returning the pistons to rest after a delivery; an intermediate body (9) inside the pump body provided with an annular groove (92) facing the first piston. The edges (521, 522) of the second cylindrical wall (52) and the edge (531) of the annular lip (53) define three sealing zones, each having a sealing profile formed by at least two surfaces co-operating with corresponding surfaces belonging to each annular groove (62, 63, 92) provided in the bottom member and in the intermediate body.
