Keep Your Wood Boiler System Moving With the Taco 2400-20-WB3P Circulator Pump
Keep water moving efficiently through an unpressurized outdoor wood boiler system with a pump built for high-capacity circulation. The Taco 2400-20-WB3P (2400-20-WB3P) is a 1/6 HP cast iron circulator designed specifically for outdoor wood boiler applications. Its close-coupled motor, stainless steel shaft, non-ferrous impeller, and durable carbon/silicon-carbide mechanical seal provide reliable circulation with minimal routine maintenance. With a compact design and up to 32 GPM of flow, it's a dependable choice for demanding hydronic heating systems.
Key Features
Built for Wood Boiler Systems
Designed specifically for unpressurized outdoor wood boiler applications, this circulator provides the high-capacity water movement these systems require for dependable heat transfer.
Durable Pump Construction
The cast iron casing, stainless steel shaft, and non-ferrous impeller are built to withstand demanding hydronic heating conditions. A carbon/silicon-carbide mechanical seal further supports long-term reliability.
Powerful, Maintenance-Friendly Motor
The close-coupled 1/6 HP motor delivers strong starting torque while permanently lubricated bearings eliminate routine bearing maintenance. Thermal protection also helps safeguard the motor during operation.
Compact Retrofit-Friendly Design
The space-saving design fits easily into existing hydronic piping layouts, while universal flange-to-flange dimensions make the circulator a practical replacement option for compatible systems.
Installation Notes: Install the circulator with the motor shaft horizontal and use the supplied O-ring gaskets. The pump is for indoor use only and must be installed in a weather-tight enclosure when used with an outdoor wood boiler. Do not run the pump dry.

Taco 2400-20-WB3P FAQ
What is the Taco 2400-20-WB3P used for?
The Taco 2400-20-WB3P is a high-capacity circulator designed specifically for unpressurized outdoor wood boiler systems. It moves heated water from the wood boiler through the connected hydronic heating system, helping transfer heat where it's needed. Its 1/6 HP motor and 2400-WB pump design are intended for applications that require more circulation capacity than smaller residential circulators provide.
How do I know if the Taco 2400-20-WB3P is the right size pump for my wood boiler?
The right circulator depends on the system's required flow rate and total head loss, not simply the size of the wood boiler. The 2400-20-WB3P's performance curve reaches approximately 32 GPM at low head, while available head decreases as flow increases, so the pump should be selected based on the actual piping, fittings, heat exchanger, and system resistance.

Can the Taco 2400-20-WB3P be used for a regular hydronic heating system?
The 2400-20-WB3P is specifically designed for unpressurized outdoor wood boiler applications rather than being a general-purpose replacement for every hydronic circulator. Taco recommends stainless steel body circulators for open systems when additional corrosion protection is needed.
What is the difference between a wood boiler circulator and a standard circulator pump?
A wood boiler circulator is designed around the higher flow requirements and operating conditions commonly found in outdoor wood boiler systems. The Taco 2400-WB series uses a close-coupled, thermally protected motor, stainless steel shaft, non-ferrous impeller, and mechanical seal specifically for these applications.
How do I use GPM and head to select a Taco circulator pump?
GPM and head work together to determine whether a circulator can provide the required flow through a specific hydronic system. A pump may be capable of 32 GPM at low resistance, but its available flow decreases as system head increases, so the pump curve should be matched to the system's calculated head loss and required flow rate.
