Description

Bell & Gossett 103260LF 1/40 HP NBF-12F/LW Bronze Circulator Pump (Lead Free)
A lead-free bronze wet-rotor circulator pump used to move water in hydronic/heating and open-loop hot-water recirculation applications where the specified Bell & Gossett NBF pump is required.

Key Features
  • 115V, 1/40 HP circulator pump
  • Flanged x flanged connection
  • Performance listings: 17 max GPM, 12 ft max head
  • 150 max PSI; 230°F max temperature
  • Bronze construction; listed as lead free
  • Xylem describes NBF wet-rotor pumps as in-line circulators designed for open (potable) water systems with 100% lead-free bronze bodies, available in flanged/union/sweat models, and suitable for residential or light commercial potable or heating applications.

Compatibility & Applications
  • Listed for heating applications; commonly used for hot-water circulation where a small in-line wet-rotor circulator is specified.
  • This model is listed as replacing 103260.
  • Must only be used where the manufacturer specifies this exact part number: 103260LF.

Installation & Operation Notes
  • Installation should be performed by a qualified hydronic/HVAC technician.
  • Reference the pump installation instructions and the system's service/installation manual for correct piping orientation, wiring, and startup/checkout.
  • SupplyHouse lists a 3/4" stainless steel pump flange set (lead free) as a commonly paired item; select the correct flange/connection components per the piping configuration.

Maintenance & Troubleshooting
  • Typical service drivers include loss of circulation (no/slow hot-water return, poor loop performance) or pump failure requiring replacement.
  • If performance seems low after installation, verify system conditions (air removal, check valves, flow restrictions) per the system documentation
  • Use the pump/system troubleshooting guidance to confirm the pump is the root cause before replacement.

User Reviews & Q&A Summary
  • Restores hot water/recirculation: Reviews frequently mention replacing a failed recirculation pump and getting "hot water again."
  • Straightforward install: Multiple reviewers describe installation taking under an hour and the pump working well immediately.
  • Included parts: At least one reviewer notes it came with gaskets, which they did not expect.

Seems to be working fine, 3rd one.

THis is our third one from Pex/Supply House. Seems to last 2-3 years and goes belly up.

Does the job.

Doesn't seem to move as much water as the curve suggests, but its working fine and doing the job. Came with gaskets, which I didn't expect

Direct replacement-worked great.

Direct replacement. Original place did not have the exact pump and it was 30% higher. Arrived in a short amount of time and took about 15 minutes to swap.
