Companion flanges 3/4"–1.5" (iron, SS, bronze sweat, shut-off). SS variant 2400-45S-3P. The 230V-only 2400-45Y-3P is marked obsolete by distributors — the dual-voltage -3P is the current number.
Curve-specific duty for the -45 frame: the MFR submittal publishes only the series max above — send the pump's performance point and we will confirm against the Taco curve.
Confirming the right replacement
Before we quote, compare these fields on your failed pump's nameplate. If any of them differ, send us a photo of the nameplate and we'll match it exactly rather than guessing:
- Full model number — including the part number (e.g. B&G P/N) where one exists
- Voltage and phase
- System duty: flow (GPM), head (ft), and fluid — heating water vs. potable water matters
- Flange size and orientation for in-line replacements
