Abstract
1437636 Centrifugal pumps ALLISCHALMERS CORP 6 Aug 1973 [11 Aug 1972] 38959/75 Divided out of 1437635 Heading F1C A rotary pump comprises a plurality of fixed vanes 27 substantially radially disposed around the pumping element 24, the inner ends of the vanes being unevenly spaced and the outer ends of the vanes being evenly spaced. The inner ends of alternate vanes may be spaced a greater distance from the outer ends of the blades of element 24 than the inner ends of the other vanes, Fig.3 (not shown).
