A gear pump comprises a casing having an inlet, an interior, and an outlet. An inlet gear is positioned at the inlet and pressurizes fluid received at the inlet. A drive gear is positioned at the outlet of the casing, the drive gear receiving fluid pressurized by the inlet gear to output pressurized fluid at the outlet. A speed-reduction gear is meshed to the drive gear and connected to the at least one inlet gear, the speed-reduction gear having a greater number of teeth than the drive gear to reduce a rotational speed from the drive gear to the inlet gear, such that the inlet gear has a lower speed that the drive gear. An input shaft is coupled to the drive gear and receives a rotational input to actuate the drive gear. |
