External Gear Pump

A type of positive displacement pump that uses the meshing gears to pump fluid by displacement. Gear pumps are commonly used in hydraulic fluid power systems and widely used in chemical installations to pump fluid with a certain viscosity. There are two main variations: external gear pumps, which use two external spur gears, and internal gear pumps, which use an external and an internal spur gear.
