Zusammenfassung:	A selective flow hydraulic gear pump has an integral unit with a front pump section and a rear pump section. The front pump section has a pumping gear set, gear plate, and bearing plate housing. The rear pump section has a pumping gear set, gear plate, and cover housing. The integral unit has an inlet port common to both the bearing plate housing and the cover housing. Check valves and solenoid operated control valves are contained within the bearing plate housing and the cover housing and are associated with a first fluid conduit. A second fluid conduit is in communication with and extends between the bearing plate housing an outlet port in the cover housing.
