Abstract

An impeller rotor (30) includes a plurality of fluid circuits (106) arranged circumferentially about an axis (44) within the impeller rotor (30). Each of the fluid circuits (106) includes a first outlet passage (110), a second outlet passage (112) and an inlet passage (108) fluidly coupled to the first outlet passage (110) and the second outlet passage (112) in parallel. A seal runner (118) includes a bore (132), a sidewall (126) and a rim (128). The bore (132) is fluidly coupled to the first outlet passage (110) of each of the fluid circuits (106). The rim (128) projects radially out from the sidewall (126) to an outer end (164) of the rim (128). The rim (128) is seated in a recess (204) in the impeller rotor (30). The rim (128) includes a flat disposed at the outer end (164) of the rim (128). The flat of the rim (128) is configured to engage a flat of the impeller rotor (30) to rotationally fix the seal runner (118) to the impeller rotor (30).
