A hydraulic vane pump (10), including a top section (12), a middle section (14), a vane rotor assembly (16) and a bottom section (18) secured together to form a single assembly. The vane pump (10) has a fluid feed chamber (20) to supply fluid directly to the top of a bore (32) formed in the middle section (14). Fluid from the feed chamber (20) also passes through a bypass chamber (28) into a fluid pocket (24) in the bottom section (18) and into the bottom of the bore (32). A vane rotor assembly (16) is used to force fluid from the bore (32) out the outlet chamber (26). By supplying fluid to both the top and bottom of the bore (32) cavitation is reduced. By feeding fluid from a single side of the hydraulic vane pump (10), packaging requirements are minimized.
