Hydraulic Gear Pump

Hydraulic gear pump, Gear pumps are positive displacement rotary pumps used to transport high pressure and high volume flows. They function through the use of two or more internal gears that create vacuum pressure, propelling the fluid media. Typically a rotating assembly includes a driving gear and a driven gear. As each tooth of the gear makes contact, the load moves to the next tooth and fluid moves with each contact. Internal gear pumps or “gear within a gear” pumps may have their smaller gear turning in the same direction as the larger gear, creating suction to move the pumped fluid media. At various points during the process of turning, the gears create a seal between the inlet and outlet sides of the rotation assembly chamber or body.
