Bell & Gossett 106197LF 100 BNFI Bronze Pump 1/12HP

Residential hot-water return systems can evaluate the Bell & Gossett 106197LF Series 100 BNFI with 1/12 HP power, 115 V operation, lead-free bronze construction, and a bronze non-ferrous impeller.

The sleeve-bearing design requires periodic oiling with the specified lubricant, making maintenance access important during installation planning. NSF-61 certification, an alloy-steel shaft with bronze sleeve, and the listed precision potable-water application provide additional material and compliance references for system selection.

Technical Details

- The 1/12 HP motor establishes the listed power class for residential loop evaluation.
- 115 V operation supports electrical planning for compatible hot-water return systems.
- Lead-free bronze construction provides the documented body material for potable-water review.
- A bronze non-ferrous impeller identifies the rotating component for material comparison.
- Sleeve bearings require periodic oiling, creating a documented maintenance obligation.
- An alloy-steel shaft with bronze sleeve provides the listed shaft construction.
- NSF-61 certification identifies the documented compliance reference for potable-water applications.

Performance and Application

The 106197LF is listed for precision potable-water loops and residential hot-water return service. Exact flow, head, NPSH, pressure, temperature, pump curve, and efficiency values are not supplied, so NSF-61 certification and material selection do not establish a guaranteed circulation rate or complete hydraulic suitability.

Installation Requirements

Confirm 115 V power, two-bolt flange compatibility, flow direction, shaft and bronze-sleeve fitment, periodic oiling access, water temperature, system pressure, and NSF-61 project requirements before commissioning. The sleeve-bearing arrangement should remain accessible for lubrication and inspection during normal maintenance service.

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 defects in materials and workmanship. Proper installation and intended use are required, while misuse, alteration, negligence, and contrary operation are excluded. Periodic sleeve-bearing oiling is required.
