Flow columns are digitized from the published 60 Hz curve in the CR, CRN 95-255 Data Booklet (60 Hz, 2026), p. 45 (water at 68 °F), and rounded down, at about 20%, 50% and 75% of 1,750 GPM, the last regular flow every curve in this listing reaches; the curves end at 1,752.8 GPM. Full curves are in the product images. On CR 255-3, CR 255-4-1 the curve reads above the published shut-off at low flow (by up to 3 ft); the published shut-off is kept and the flow columns follow the curve.\u003c\/p\u003e\n\u003cp style=\"font-size:13.5px;margin:14px 0 8px\"\u003e\u003cstrong\u003eMotor each model needs\u003c\/strong\u003e (Grundfos price list and catalog; the motor is ordered separately):\u003c\/p\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\u003ctable class=\"gs-tbl\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eMotor HP\u003c\/th\u003e\n\u003cth\u003eNEMA frame\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-1-1\u003c\/td\u003e\n\u003ctd\u003e60\u003c\/td\u003e\n\u003ctd\u003e364TSC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-1\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003ctd\u003e405TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-2-2\u003c\/td\u003e\n\u003ctd\u003e125\u003c\/td\u003e\n\u003ctd\u003e444TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-2-1\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003ctd\u003e445TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-2\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003ctd\u003e447TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-3-3\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003ctd\u003e447TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-3-2\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003ctd\u003e447TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-3-1\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003ctd\u003e449TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-3\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003ctd\u003e449TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-4-3\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003ctd\u003e449TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-4-2\u003c\/td\u003e\n\u003ctd\u003e300\u003c\/td\u003e\n\u003ctd\u003e449TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCR 255-4-1\u003c\/td\u003e\n\u003ctd\u003e300\u003c\/td\u003e\n\u003ctd\u003e449TSD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:10px;margin:22px 0 4px\"\u003e\n\u003ca href=\"\/pages\/well-irrigation-pump-sizing-calculator\" style=\"flex:1 1 200px;text-align:center;display:block;background:#B3122A;color:#ffffff;font-family:Arial Black,Arial,sans-serif;font-size:12px;text-transform:uppercase;letter-spacing:1.2px;padding:11px 18px;text-decoration:none\"\u003eWell \u0026amp; Irrigation Calculator\u003c\/a\u003e\u003ca href=\"\/pages\/pressure-tank-sizing-calculator\" style=\"flex:1 1 200px;text-align:center;display:block;background:#B3122A;color:#ffffff;font-family:Arial Black,Arial,sans-serif;font-size:12px;text-transform:uppercase;letter-spacing:1.2px;padding:11px 18px;text-decoration:none\"\u003eTank Calculator\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gs-sec\"\u003e\n\u003cdiv class=\"gs-h\"\u003eBefore You Buy — The Limits That Decide the Fit\u003c\/div\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\u003ctable class=\"gs-tbl\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eCheck\u003c\/th\u003e\n\u003cth\u003eWhat decides the fit\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor\u003c\/td\u003e\n\u003ctd\u003eOrder a NEMA C-face motor at the HP and frame Grundfos lists for your model in the motor table under Models \u0026amp; Performance.
