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 has an upper region located at the highest location of the pumping chamber and in the region of which the pumping chamber is placed in communication with at least one intake pipe for a fluid product.

A positive-displacement pump for fluid products, the pump comprising a pump body forming a pumping chamber, a piston mounted for sliding movement within the pumping chamber and being controlled for reciprocating movement within the pumping chamber in order to vary a fluid-product receiving volume of the pumping chamber, a pumping pipe leading into an upper region of the pumping chamber and being in fluid communication therewith, the upper region being located at a highest location of the pumping chamber, an intake pipe in fluid communication with the pumping chamber, the intake pipe communicating with a tank containing fluid product and positioned at a greater height with respect to the positive-displacement pump so as to produce a hydraulic head and a fluid travel path with a constant descent from the tank to provide fluid product from the tank to the pumping chamber.
A positive-displacement pump for fluid products, said pump comprising:
- a pump body forming a pumping chamber, the pumping chamber having a summit zone which includes the highest location of the pumping chamber and an opening disposed adjacent and in fluid communication with the summit zone;
- a pumping pipe leading into the opening of the pumping chamber;
- an intake pipe disposed to receive a fluid product from a tank positioned at a greater height than the pump to produce a hydraulic head, the intake pipe being in fluid communication with the pumping pipe to provide the fluid product from the tank thereto, the intake pipe defining a fluid travel path for the fluid product which descends from the tank;
- and
- a piston slidably mounted in the pumping chamber, the piston being control.
