Claim 8:
9. The apparatus according to claim 1
wherein the centrate centripetal pump chamber is bounded vertically by a lower circular axially centered centrate centripetal pump chamber surface,
wherein the lower centrate centripetal pump chamber surface includes an axially centered lower centrate centripetal pump chamber opening, wherein the feed tube extends through the lower centrate centripetal pump chamber opening,
an upper axially centered circular centrate centripetal pump chamber surface,
wherein the upper centrate centripetal pump chamber surface includes an axially centered upper centrate centripetal pump chamber opening, wherein the feed tube and the vertically extending centrate discharge tube extend through the upper centrate centripetal pump chamber opening,
wherein the centrate centripetal pump includes a substantially annular centrate pump opening, wherein centrate from the centrate pump chamber enters the centrate centripetal pump through the substantially annular centrate pump opening,
wherein the substantially annular centrate pump opening is radially disposed from the axis a centrate pump opening distance,
wherein the lower centrate centripetal pump chamber surface includes
a plurality of angularly spaced, radially and upward extending lower centrate chamber vanes, wherein the lower centrate chamber vanes extend radially outward beginning from the lower centrate centripetal pump chamber opening a lower centrate vane distance,
wherein the lower centrate vane distance is less than the centrate pump opening distance,

wherein the upper centrate centripetal pump chamber surface includes a plurality of angularly spaced, radially and downward extending upper centrate chamber vanes,
wherein the upper centrate chamber vanes extend radially outward beginning from the upper centrate centripetal pump chamber opening an upper centrate vane distance, wherein the upper centrate vane distance is less than the centrate pump opening distance.
