Abstract
A positive-displacement pump for fluid products, in particular paints, colorants and the like, includes a pump body in which there is formed a pumping chamber, in which a piston is mounted for sliding and is controlled so as to advance and withdraw in order to vary the useful volume of the pumping chamber. The pumping chamber extends in accordance with a longitudinal axis which is inclined, in a non-vertical manner, with respect to a horizontal plane and having an upper region which is positioned at a greater height with respect to a horizontal plane and in the region of which the pumping chamber is placed in communication with at least one intake pipe of a fluid product.
