External gear pumps are similar in pumping action to internal gear pumps in that two gears come into and out of mesh uses two identical gears rotating against each other one gear driven by a motor and it in turn drives the other gear. Each gear is supported by a shaft with bearings on both sides of the gear. As the gears come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by gear teeth as they rotate.

Liquid travels around the interior of the casing in the pockets beween the casing – it does not pass between the gears.

Finally the meshing of the gears forces liquid through the outlet port under pressure Because the gears are supported on both side external gear pumps are quiet-running and are routinely used for high pressure applications such as hydraulic applications with no overhung bearing loads the rotor shaft can’t defect and cause premature wear.
