| Product line | 00R series ECM circulator |
Every 00-series (“double-oh”) circulator uses Taco's replaceable cartridge — the cartridge holds all the moving parts, so a failed unit can often be repaired with a cartridge swap instead of a full replacement. Cast iron = closed-loop heating only; stainless/bronze = potable water.
00R series: replaces the 00R-MSF6-1 and 00R-MSF6-2. The 00R-MS1-2P is a different, discontinued pump — not the same.
115V version: see the VR3452-HY1-FC1A01.
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
