Bell & Gossett 104301 Ecocirc XL 36-45 Iron Body Circulator

Commercial hydronic HVAC uses Bell & Gossett 104301 Ecocirc XL 36-45 for variable-speed heating and cooling circulation. Its ECM motor delivers up to 45 GPM against 36 feet of head, while proportional-pressure, constant-pressure, and fixed-speed modes adapt pump output to changing loop demand. Confirm the 115 V single-phase supply, IP44 protection, BMS readiness, and system curve before startup.

The Ecocirc XL 36-45 uses a cast iron body, push-button user interface, and high-efficiency ECM motor. Its 14°F to 230°F operating range supports compatible hydronic systems, while verified data does not include amp draw, RPM, impeller material, seal type, connection size, dimensions, weight, thermal protection, or self-priming capability. Match the circulator to the commercial heating or cooling duty point before installation.
