Axial pistones Hydraulic Pump for PC340

The first one, is the mechanical action of rotation that creates the vacuum in the suction area and allows the atmospheric pressure to make the oil rise from the tank to the suction pipe; the second one is based on the fact that the pump, carrying the fluid (flow), does not generate pressure, so as the oil meets.
