DISK PUMP WHEEL Russian patent published in 2006 - IPC F04D29/18 

FIELD: space engineering, chemical industry.

SUBSTANCE: proposed disk pump wheel can be used in electrolysis and temperature control systems of spacecraft articles and chemical engineering. Disk pump wheel has carrying and cover disks welded together and axial bridges made integral with cover disk and arranged over outer edge between disks. Rod of additional axial bridges is made over inner edge of cover disk. Made between axial bridges and additional axial bridges are n(N=3,4, etc) projections arranged at equal pitch over circumference, center of which is arranged on longitudinal axis of wheel. Each axial bridge and additional axial bridge is made with height equal to height of projections, and carrying and cover disk are welded in places of contact of projections with carrying disk.

EFFECT: improved chemical resistance and manufacturability.
