A blood pump (20) includes a stator assembly including a fluid inlet (24) and a fluid outlet (26). A rotor assembly (120) includes an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). A motor (50) imparts rotation of the impeller (40) about the axis (44). The motor (50) includes a motor stator (52) fixed to the stator assembly (122), a motor rotor (54) fixed to the rotor assembly (120), and a radial motor gap (34) between the stator (52) and the rotor (54). The pump (20) is configured to direct a mixed blood flow from the fluid inlet (24) to the fluid outlet (26) and a wash flow through the motor gap (34).
