Grundfos’s published duty point sits below its own curve by more than 3% of shut-off on CRNE 155-1-1 (25 HP) (by up to 6 ft at the rated flow); the table follows the curve. On CRNE 155-1-1 (25 HP) the curve rises above its zero-flow head at low flow (by up to 3 ft); the published shut-off is kept and the flow columns follow the curve.
