An improved pump for sprayer, which is essentially characterized by its piston being constituted by a bell that, inside, is fitted with a sleeve that, at one of its ends, is bent over the mouth of the bell, being trapped between said mouth and the bent part of the sleeve, a washer of elastic material mounted on the bent end of the sleeve, which washer constitutes the piston proper of the pump because its diameter is slightly greater than that of the bell, moving the described assembly inside a second sleeve that constitutes the cylinder of the pump and that, by plug, is fixed to the body of the sprayer, which body constitutes the bottom of the cylinder of the pump.
