Zusammenfassung:	ADJUSTABLE VORTEX PUMP A vortex pump which has been converted from a centrifugal pump by interposing an annular spacer between the power frame and casing of the centrifugal pump to provide space for a vortex impeller which has been substituted for the centrifugal impeller. An adjustable vortex impeller consisting of a hub portion with an annular flange having a plurality of sets of holes circumferentially spaced thereon, a plurality of vanes each having a plurality of holes in its root portion, and bolts for fastening each of the vanes in a plurality of different positions on the hub by passing through different pairs of aligned holes in the flange and in the roots to provide different impeller diameters while maintaining the discharge angle of the vanes within a small predetermined range. A plurality of sets of vanes of different sizes can be selectively mounted on the hub to further extend the range of impeller diameters. ?
