Abstract

The pump has a pump body (6) provided with a central chamber housing two pinions engaging with each other, an opening for aspiring a low pressure liquid and high pressure output channel connected to a user hydraulic circuit. The channel is configured to form a dampening unit that dampens pulsations in a high pressure liquid, produced by the pinions. The channel is constituted of output, vertical, horizontal channels (37, 41, 42) and a groove (39) forming bends of an angle of ninety degree, at respective ends of the sections.
