Bell & Gossett 104300 Ecocirc XL 20-35 Iron Body Circulator

Description

Commercial heating controls use Bell & Gossett 104300 Ecocirc XL 20-35 for closed-loop circulation with adjustable pump response. Its ECM motor delivers up to 35 GPM against 20 feet of head, while proportional-pressure, constant-pressure, and fixed-speed modes support changing system demand. Confirm the Modbus RTU and BACnet MS/TP readiness, fluid temperature range, and control wiring before startup.

The Ecocirc XL 20-35 uses a cast iron body with ECM motor technology and a listed operating range from 14°F to 230°F. Its communication interface supports compatible building-management connections, while verified data does not include voltage, phase, amp draw, RPM, seal type, connection size, dimensions, weight, thermal protection, or self-priming capability. Match the circulator to the closed-loop heating or cooling curve before installation.

Key Features of Bell & Gossett 104300 Ecocirc XL 20-35
