Abstract

244,989. Marzullo, V. May 18, 1925. Disc-supported-blade fans and pumps; impeller blades.-The rotor of a centrifugal pump has an inner set 7 and an outer set 8 of curved blades; the blades of one set are angularly displaced relatively to those of the other set and the blades of Loth sets are concave in the same direction. A set 7 of blades is carried on each side of the impeller disc 6 and a set 8, which are circular in shape, on the periphery of the disc. The two arms 12 of the inlet chamber are arranged at the sides of the pressure chamber 14. The outer set 8 of curved blades may be replaced by straight blades.
