One embodiment of the pump system includes a cover housing and a main body affixed to one another for operation. A drive and idler gear may be mounted within a gear chamber in the main body for rotation there about, and inlet fluid may be provided on both the axial and radial surfaces of the drive and idler gear. The cover housing may be outfitted with one pressure relief channel or with two pressure relief channels of different geometric sizes and with different actuation pressures. The drive and/or idler gear may have dimples fashioned on an axial surface thereof, and lubricant troughs may be fashioned at various locations in the main body and/or the cover housing to reduce wear within the pump.
