VERTICAL RADIAL-FLOW PUMP Russian patent published in 2013 - IPC F04D1/00 F04D29/44 

FIELD: engines and pumps.

SUBSTANCE: proposed pump comprises housing, impeller with top and bottom vaned rims, ring distributor and pipe bend with outer and inner rings to make manifold with pressure pipe. Said distributor is arranged between pipe bend and manifold. Rings in lower part arte composed elliptical concentric bottoms along pump axis. Channels extending to bottom rim are composed of branch pipes to pass through said bottoms while their axes extend through the center of said bottoms. Guide vanes are arranged from distributor to said branch pipes. The latter communicate with bottom rim via lower confuser with flat radial ribs between branch pipes located by its inner part from branch pipes and by outer part from inner ring to bottom rim. Circular baffle is arranged between housing and outer ring to separate feed line to rims. Channels to top rim are located between two circular elements connected by radial ribs and jointed thereto by flat ribs combined into top confuser within the limits of diameter of intersection of inner generating lines of branch pipe, confuser inner part and inner bottom.

EFFECT: simplified design, higher efficiency, longer life, smaller overall dimensions.
