Abstract (en)
A monolithic impeller (10) for a fluid pump is described, the impeller (10) comprising a gear opening (12) defined by a cylindrical member (14) including an inner surface (16) being splined for receiving a gear shaft with said cylindrical member (14) defining an impeller axis, a plurality of blades (20) including an arcuate configuration extending outwardly relative to said impeller axis, each of said plurality of blades (20) including a proximal end (22) being disposed proximate said cylindrical member (14) and a distal end (24) disposed radially outwardly from said cylindrical member (14), a cover member (28) extending radially outwardly to said distal end (24) of said plurality of blades (20) and defining a fluid inlet (26) being concentric with said impeller axis, a hub member (44) spaced from said cover member (28) by said plurality of blades (20) and extending radially outwardly from said cylindrical member (14); and said proximal end (22) of said blades (20) extending radially inwardly of said fluid inlet (26) and said distal end (24) of said blades (20) terminating at a common concentric diameter as an outermost portion of said cover member (28) and said hub member (44).
