Bell & Gossett 103267 Circulator
The Bell & Gossett 103267, also known as the Model NRF-9F/LW, is a high-efficiency cast iron wet rotor circulator engineered for closed-loop hydronic heating systems. Operating at 115Vac with a single-phase motor, this pump delivers a consistent 2800 RPM while maintaining a low power draw of only 41 Watts and 0.40 Full Load Amps. Deciphering the needs of residential and light commercial loops, this single speed inline pump features a high-starting torque motor that ensures reliable startups even after seasonal shutdowns. The wet rotor design eliminates the need for mechanical seals and coupler maintenance, providing silent operation by using the pumped fluid to lubricate the internal bearings. Designed for versatile installation, the flange-to-flange dimensions are compatible with 3/4", 1", 1 1/4", or 1 1/2" flanges, making it a standard replacement for many hydronic heating circulators in the field.
Key Benefits
- Maintenance-Free Operation: The wet rotor design utilizes system fluid for lubrication, eliminating manual oiling and seal replacements.
- High Starting Torque: Built-in B&G 103267 motor characteristics prevent sticking in systems with high mineral content.
- System Compatibility: Universal flange mounting allows for seamless integration with multiple pipe sizes using standard B&G flange kits.
- Durability: Rugged cast iron pump housing designed for long-term performance in oxygen-free closed loops.
- Efficient Performance: Optimized 41-watt power consumption balances head pressure requirements with energy savings.
Common Questions
Can the NRF-9F/LW be used in an open domestic water system?
No, this model features a cast iron housing intended only for closed-loop hydronic systems. For potable water applications, a bronze or stainless steel circulator is required to prevent oxidation.
What is the maximum fluid temperature rating for this circulator?
The Bell & Gossett NRF-9F/LW is typically rated for a maximum operating temperature of 225°F, making it suitable for high-temp baseboard and radiator applications.
Does this pump require a specific mounting orientation?
Yes, the motor shaft must be installed in a horizontal position to ensure proper lubrication of the bearings and to prevent air entrapment in the rotor chamber.
