摘要： A stirring impeller, an arrangement, and a use. The impeller comprises a hub disc comprising a shaft attachment structure arranged centrally in the hub for receiving a shaft centrally and perpendicularly from an upper side of the hub disc, a plurality of upper blades arranged on the upper side of the hub disc, and a plurality of lower blades arranged on a lower side of the hub disc. At least one of said plurality of upper blades is arranged to have jet angle of 5°-45°, and the lower blades have a jet angle that is different than said jet angle of least one of said plurality of upper blades.
