An impeller for a torque converter includes a rotating housing portion, a blade portion configured to create fluid flow for pumping fluid to a turbine of the torque converter, and an impeller hub portion configured to couple the impeller to the torque converter and rotate about an output shaft of the torque converter. The impeller hub portion defines an inner surface having an annular recess, and at least one inlet passage and at least one outlet passage to provide flow paths for fluid entering and exiting the impeller. The torque converter further includes a wear member at least partially received in the annular recess, the annular wear member being formed from a ferrous material. The rotating housing portion, the blade portion, and the impeller hub portion are integrally formed as a single piece casting.
