In external gear pumps, two gears mesh inside a closed housing. When the gears rotate, the fluid fills the space between the gear teeth and is transported from the suction side to the discharge side, passing around the outer circumference of the gears. In the areas where the teeth mesh, the fluid is unable to leak and is therefore pushed towards the outlet.

Thanks to their characteristics, they are commonly used in applications where pressurizing or metering fluids with high precision and very low pressure fluctuations are required.
