Bell & Gossett ecocirc XL 55-45 High-Efficiency ECM Circulator Pump
Engineered to deliver advanced energy-saving automation across high-volume commercial thermal systems, the Bell & Gossett ecocirc XL 55-45 is a variable-speed, smart wet-rotor circulator powered by state-of-the-art electronically commutated permanent magnet motor (ECM/PM) technology. This smart pump dynamically alters its operating speeds to match shifting system demands precisely, dramatically slashing mechanical energy consumption by up to 80% compared to old-school single-speed booster pumps.
Featuring a user-friendly interface with an intuitive four-button layout, the ecocirc XL supports Proportional Pressure, Constant Pressure, and Constant Speed operating modes. It is equipped with advanced remote building management integration protocols (including standard MODBUS® and BACnet®), an automated thermal Night Setback mode, and integrated software dry-run protection to permanently protect the internal carbon sleeve bearings from dry-fire damage.
Key System Performance Baselines:
- Smart ECM Motor: High-efficiency 0.5 HP variable-speed permanent magnet motor scales dynamically to optimize systemic power draw across shifting building loops.
- Condensation Guard Architecture: Complete electronics isolation separation barrier allows safe, reliable runtime in chilled water networks down to 14°F (-10°C) without internal condensation short-circuits.
- System Connectivity: Seamless out-of-the-box communication architecture interfaces directly with local building management loops for remote performance tracking and system tuning.
- Flange Matrix: Robust flanged connection profile interfaces smoothly with standard 1", 1-1/4", or 1-1/2" NPT companion flange hardware (companion flange kits sold separately).
⚠️ Application Profile: This rugged cast iron body model is specifically engineered for closed-loop hydronic heating infrastructure, radiant loops, snow-melt setups, and HVAC chilled water loops. It is not rated for open-loop domestic potable water lines.
