Ensure consistent hot‑water delivery throughout a building with a reliable circulator pump designed for residential and light‑commercial hydronic systems. The 103351LF model, part of Bell & Gossett's NBF‑33 series, provides 1/15 HP of steady flow for efficient loop performance.
The pump features a sealed‑tight, bearing‑lubricated motor coupled to a compact volute housing that creates a gentle, vortex‑induced flow. Its low‑speed operation minimizes noise while maintaining the pressure needed to overcome system resistance.
Key System Performance Baselines:
- Flow Capacity: Up to 3 GPM at 10 ft head.
- Power Consumption: 1/15 HP (approx. 125 W).
- Noise Level: Quiet operation below 45 dBA.
- Installation Flexibility: 3/4‑in. NPT inlet/outlet for easy retrofit.
⚠️ Application Profile: Ideal for domestic hot‑water recirculation, small‑capacity boiler feed loops, radiant floor heating circuits, and commercial kitchen water loops.
