Shut-off is Grundfos’s published maximum head. Flow columns are read from the 100% speed curve on the Grundfos 60 Hz chart for each model and motor (water at 68 °F), digitized and rounded down, at 20%, 50% and 75% of 12 GPM, the last regular flow every curve in this listing reaches; the curves end at 12.7 to 14.6 GPM. Where a model is offered on two motor sizes, the smaller motor reaches its power limit sooner and its curve falls away at high flow. At reduced speed the pump runs on a lower curve; full Grundfos charts with the reduced-speed curves are in the product images. Grundfos’s published duty point sits above its own curve by more than 3% of shut-off on CRE 1-21 (3 HP), CRE 1-17 (2 HP, 3Ph), CRE 1-15 (2 HP), CRE 1-9 (1 HP, 3Ph), CRE 1-13 (1 1\/2 HP) (by up to 84
