Abstract (en)
The finding describes a separation system (10) between the high-pressure chamber and the low-pressure chamber in a volumetric pump of the type with gears (36, 38). The separation system (10) comprises a hub (12), torsionally forming a unit with a central pin (14) around which rotates a first gear (36) of the gears of the pump, and at least one half-moon shaped dividing wall (16), the function of which is to separate the high and low pressure chambers that are created following the rotation of the gears (36, 38) of the pump. The half-moon shaped dividing wall (16) consists of a separate component with respect to the hub (12) and is provided with connection means (18, 20) to the body of the hub (12) itself, so as to improve the efficiency and the resistance to wear of the separation system (10) and of the entire pump.
