Shut-off is Grundfos’s published maximum head for each model. Flow columns are read from the Grundfos 60 Hz curve for each model (water at 68 °F), digitized and rounded down, at about 20%, 50% and 75% of 5.5 GPM, the last regular flow every curve in this listing reaches; the curves end at 5.6 to 5.7 GPM. Full curves are in the product images. The CR 1s-2 curve reads 58 ft at zero flow against 53 ft published; the published shut-off is shown and the flow columns follow the curve. Grundfos’s published duty point sits below its own curve by more than 3% of shut-off on CR 1s-2, CR 1s-6, CR 1s-11, CR 1s-25, CR 1s-27 (by up to 63 ft at the rated flow); the table follows the curve.
