The blood pump has a blood flow path that passes about the rotor, with the rotor having a peripheral edge surrounding an end face. The end face has a profiled surface that augments blood flow radially outwardly from a central portion of the end face toward the peripheral edge as the rotor rotates when compared with a flat end face.
