The figure at left shows a cross section of a two section pump along with the path of the fluid within the unit as indicated by arrows. As in the single section pump, part of the discharge flow enters the lubrication groove in the pressure plate on each end of the gears and is fed to each bearing. The oil is again collected at the ends of the bearing and returned back to the inlet end through a series of drilled passages. |

The isolation plates used in reversible gear pumps are shown at left. Two
of these plates are needed in the bottom of the housing and two in the
top. The isolation plates hold the seal components in place. The
plates with a round edge along the outer radius on one edge go in the bottom of
the housing. Plates with the square edges on the radius go next to the
top flange.
