DN1/DN2 are nominal connection sizes, not measured clear bores. Other numerical dimensions are millimetres; bolt callouts retain the source hole counts and diameters. The original installation outline and this exact model row are used, not package dimensions or a neighbouring standard variant. Confirm flange mating, supplied motor and service clearances.
Source and selection qualifications
LEO XZS technical table (printed page 107), model-specific installation table and original outline (printed page 118), checked 16 October 2026. Straight lines connect published numerical points only: no interpolated test points, extrapolated zero-head endpoint, best-efficiency point or certified operating range has been invented. The manufacturer’s continuous-duty guidance depends on its full curve and actual installation; obtain duty confirmation before selection.
