Abstract

In accordance with at least one aspect of this disclosure, a system (100) includes a rotor (102) configured to rotate about a rotor axis within a pump housing (104). In embodiments, the rotor (102) includes, a first end face (106) configured to interface with a stationary port plate (108), a plurality of vane slots (114) defined in the rotor (102) arranged circumferentially about the rotor axis configured to accept a respective vane (116) therein, and a plurality of lands (118) between each vane slot (114), wherein each land (118) includes a portion of the first end face (106). The rotor (102) also includes, a lubrication pad (140) defined in the first end face (106) of at least one land (118) between neighboring vane slots (114a, 114b) such that the lubrication pad (140) is fed by the neighboring vane slots (114a, 114b) to induce buildup of a lubrication film (142) between the first end face (106) and the stationary port plate (108) in the lubrication pad (140).
