Designed to maintain steady hot‑water flow in hydronic heating loops, the Bell Gossett NRF‑45 provides three speed settings for precise control. This **103404** pump delivers 1/6 HP power in a compact inline booster package.
The three‑speed motor adjusts flow rates by varying the impeller speed, allowing system pressure to be matched to demand while reducing energy consumption. Its sealed‑for‑life bearings and corrosion‑resistant housing ensure reliable operation in demanding environments.
Key System Performance Baselines:
- Flow Capacity: Up to 12 GPM at low speed, scaling to 30 GPM at high.
- Pressure Rise: Provides up to 15 ft H₂O head, suitable for typical residential loops.
- Energy Efficiency: Three‑speed design cuts motor draw by up to 40 % at low demand.
⚠️ Application Profile: Ideal for residential boiler circulations, commercial water‑to‑water heat exchangers, spa recirculation, and small‑scale hydronic heating systems.
