Bell & Gossett 104478LF 3PH Ecocirc XL N 45-375 Stainless Steel Circulator

Campus-wide potable-water distribution can evaluate the Bell & Gossett 104478LF ecocirc XL N 45-375 with 208 to 230 or 460 V three-phase power, lead-free stainless steel construction, 375 GPM maximum flow, and 45 feet of maximum head.

Modbus, BACnet, and fault-relay connectivity provide documented control-integration options for large DHW systems. The listed HI Energy Rating supports efficiency classification, but maximum flow and head are not simultaneous guarantees and require pump-curve matching.

Technical Specifications

- 208 to 230 or 460 V three-phase power establishes the electrical supply range.
- Lead-free stainless steel construction identifies the wetted-body material for potable-water review.
- Maximum flow is listed as 375 GPM, requiring comparison with actual system demand.
- Maximum head is listed as 45 feet, providing an upper hydraulic reference.
- Modbus communication supports integration with compatible building-management controls.
- BACnet communication provides an additional documented control-network option.
- A fault relay supplies a status signal for alarm and monitoring systems.

Hydraulic Performance and Application

The listed maximum performance is 375 GPM at 45 feet, with campus-wide potable distribution and ultra-high-flow domestic hot-water service identified as applications. These limits do not define a normal operating point, so final selection requires the actual system curve, NPSH, pressure, temperature, and control requirements.

Installation Requirements

Confirm three-phase voltage, connection dimensions, potable-water material requirements, flow direction, rotation, Modbus or BACnet wiring, fault-relay connections, service clearance, and operating limits before commissioning. The selected duty must remain within the approved pump curve rather than relying on maximum flow or head.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from shipment or a 1-Year Limited Warranty from installation, whichever occurs first, covering material and workmanship defects. Improper installation, misuse, alteration, negligence, and contrary operation are excluded. Communication wiring and fault-relay checks belong in commissioning records. Mulmotor provides product-information support before purchase.
