Results are a curve-coverage screen, not a final selection. Confirm the choice against the datasheet and the installation before ordering.
Curves are for water at 60 Hz. Salt water, other fluids, temperature, and 50 Hz supply are not considered.
NPSH and suction conditions are not checked.
Suction lift is not checked. A self-priming model is not confirmed to prime at any particular lift.
The system curve is assumed to be head = static + k * gpm^2 through the single design point given. Real piping, filters, and backwash duty are not modeled.
Motor voltage, phase, and enclosure are not matched to the site. See the spec rows for each model.
Variable-speed speed and watts are affinity-law estimates.
