In this configuration, the larger gear is on the outside with the gear teeth pointing inwards meshing with the smaller second gear that is inside the larger one.

Thanks to the unique & compact design of hydraulic gear pumps, they are ideal for mobile plant applications.  However, you do need to stay on top of your system monitoring to avoid and prevent system performance issues such as oil contamination, which is the number one cause of gear pump failure.
