Hydraulic gear pump: A gear pump uses the meshing of gears to pump fluid by displacement.They are one of the most common types of pumps for hydraulic fluid power applications.Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. How does a gear pump work? Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of its rotating gears and transferred to the discharge.
