WORKING PRINCIPLE

External gear pumps are similar in pumping action to internal gear pumps in that two gears come into and out of mesh to produce flow. However, the external gear pump uses twp identical gears rotating against each other; one gear is driven by a motor and it in turn drives the other gear.

1. 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 the gear teeth as they rotate.
2. Liquid travels around the interior of the casing in the pockets between the teeth and the casing it does not pass between the gears.
3. Finally, the meshing of the gears forces liquid through the outlet port under pressure.
