Abstract
A rotary gear pump includes a housing, a drive gear, and an idler gear. The housing has a central axis extending in an axial direction, and defines an intake port, a discharge port, and a gear chamber in fluid communication with the intake port and the discharge port. The drive gear and the idler gear are intermeshed, and rotatably disposed within the gear chamber for displacing fluid from the intake port to the discharge port. The drive gear has an axis of rotation that is coaxial with the housing central axis. The drive gear may be directly coupled to the idler gear of a second rotary gear pump, which idler gear has an axis of rotation that is coaxial with the axis of rotation of the drive gear.
