Hydraulic gear pump

Hydraulic gear pumps (with external teeth) (fixed displacement) are simple and economical pumps. The swept volume or displacement of gear pumps for hydraulics will be between about 1 to 200 millilitres. They have the lowest volumetric efficiency of all three basic pump types. These pumps create pressure through the meshing of the gear teeth, which forces fluid around the gears to pressurize the outlet side. Some gear pumps can be quite noisy, compared to other types, but modern gear pumps/internal gear pump are highly reliable and much quieter than older models.
