Claim 25:
26. The apparatus according to claim 1 and further comprising:
a vertically extending concentrate discharge tube,
a concentrate centripetal pump, wherein the concentrate centripetal pump is
coaxially aligned with the core,
disposed coaxially about the central tube,
positioned vertically above the centrate centripetal pump, and
in fluid communication with the concentrate discharge tube,

wherein the concentrate centripetal pump is positioned in the interior area in a concentrate centripetal pump chamber,
wherein the concentrate centripetal pump chamber is in fluid communication with the separation chamber, and wherein during rotation of the bowl the upper disc shape portion and the outer wall rotate relative to the concentrate centripetal pump,

wherein the concentrate centripetal pump includes a substantially annular concentrate pump opening, wherein concentrate from the concentrate pump chamber enters the concentrate centripetal pump through the substantially annular concentrate pump opening,
wherein the substantially annular concentrate pump opening is radially disposed away from the axis a concentrate pump opening distance,

wherein the concentrate centripetal pump chamber is bounded by a circular axially centered lower concentrate centripetal pump chamber surface and a circular axially centered upper concentrate centripetal pump chamber surface,
wherein at least one of the lower concentrate centripetal pump chamber surface and the upper concentrate centripetal pump chamber surface includes a plurality of angularly spaced, radially and vertically extending concentrate chamber vanes,
wherein the concentrate chamber vanes extend radially outward away from the axis and terminate at a concentrate vane distance,
wherein the concentrate vane distance is less than the concentrate pump opening distance.
