Taco 0011-F4 Replacement

Verified specifications

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.

0011 vs 0010: same 1/8 HP, different duty. The 0011-F4 is the high-head unit (high-pressure-drop boilers, fan coils, heat exchangers, large radiant); the 0010-F3 is high flow / medium head. Match the duty, not just the HP.

Distributor listings differ on max working pressure (125 vs 150 psi) — Taco's submittal is the tiebreaker; check the pump nameplate and we'll confirm when quoting.

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
