Oil pumps differ in the type of control: mechanical or electronic. Mechanical pumps are directly controlled by the engine, while electronic pumps are controlled by a control unit.
Gear pumps: they use two gears meshed together, one of which is driven by the other; their rotation allows the pumping of oil, which flows in the outermost part of the gears. Lobe or trochoidal pumps: they use two toothed elements, which have a slightly different axis of rotation and allow an oil pumping comparable to the gear pump, but requiring a smaller space Piston pumps: used on the old means or in case it is necessary to adjust even through a second command in addition to the speed.
