An impeller for a centrifugal pump is provided. It has an inlet side and an outlet side. Additionally, the impeller has a base, a plurality of guide elements extending from the base fluid flow channels, and a centrally disposed inlet opening. The fluid flow channels defined by the guide elements impart energy to the fluid during rotation of the impeller. The second member serves as a shroud and encloses the fluid flow channels. The centrally disposed inlet opening through the shroud admits fluid into the flow channels of the impeller to then be conducted outwardly upon rotation of the impeller.
