A gear pump for operating with reduced likelihood of cavitation occurrences in the fluid being pumped thereby, the pump having a pair of gears each supported on a corresponding one of a pair of gear with teeth provided in each gear that mesh with at least one tooth of the other when such teeth have been rotated into a meshing region in the gear plane, and with one of the gear shafts being rotatably connectable to a motor. Bearing structures rotatably support corresponding ones of each of the pair of gear shafts with the bearing structures having bearing surfaces adjacent those gear sides. A pressurized fluid passageway is provided in at least one of the bearing structures across from the meshing region and extending between surface openings at the bearing surface of that bearing structure that are positioned on opposite sides of an alignment axis in that bearing surface, the surface openings being separated from one another by at least the width of a tooth provided in the pair of gears.
