Zusammenfassung:	An auxiliary impeller for stripping is provided to improve the stripping performance of a cargo pump so that the residual amount of cargos can satisfy criteria. A cargo oil pump unloads liquid cargo in a ship by using a main impeller section and an auxiliary impeller section(10). In the auxiliary impeller section, an auxiliary impeller hub(11) is integrally installed at an end of a hub of the main impeller section. A plurality of auxiliary impellers(13) are provided along the outer peripheral surface of the auxiliary impeller hub. The auxiliary impellers are bent so that the ends thereof can protrude in the rotational direction. The auxiliary blade includes a first impeller spirally protruding along the outer peripheral surface of the auxiliary blade hub and a second impeller integrally connected to the upper end surface of the first blade so as to protrude in the rotational direction.
