Source conflicts and installation checks
The graphs and numerical ratings are separate manufacturer references, not independently certified duty data. Maximum flow and maximum head are separate limits, not one operating point. The individual curve uses approximate readings of the original orange stroke (about ±0.3 m reading uncertainty), not a fit through the rated/max table. Dimensions are source table values, not measured installation approval; confirm actual phase-specific height and the elbow/coupling interface. Nominal discharge must not be substituted for the drawing dimension D.
No extrapolated shut-off or zero-head endpoint has been invented. Confirm duty, voltage, operating immersion, actual phase, pipe interfaces and clearances before ordering.
