Armstrong Fluid Technology 116431MF-132 Pump
The Armstrong Fluid Technology 116431MF-132 is a high-efficiency H51BF circulator pump designed for reliable fluid movement in hydronic heating and cooling systems. As the direct 116431-132 replacement, this 1/4 HP circulator pump features a maintenance-free design with permanently lubricated bearings, eliminating the need for manual oiling. Built with a rugged cast iron body and a centrifugal non-ferrous impeller, it ensures optimal water delivery and durability in demanding HVAC environments. The single-phase 115V motor includes built-in thermal overload protection to safeguard the internal components against overheating. Its three-piece modular design and radially-split body allow the unit to remain in-line during service, significantly reducing labor time. Engineered for 1-inch pipe connections, this in-line pump provides a cost-effective solution for multi-stage zoning and general industrial fluid service, maintaining precise temperature control with 1750 RPM performance.

Key Benefits- Enhanced Durability: Features a cast iron body and non-ferrous impeller for long-term resistance to wear.
- Zero Maintenance: Equipped with maintenance-free, permanently lubricated bearings to reduce operational costs.
- System Security: Integrated thermal overload protection prevents motor damage during high-load scenarios.
- Efficient Servicing: The back pull-out design and radially-split body permit easy repairs without disconnecting piping.
- Universal Compatibility: Uses standard 1-inch flanges, making it a versatile booster pump for various HVAC applications.
Is the 116431MF-132 compatible with the older 116431-132 model?
Yes, the 116431MF-132 is the official updated version. It features a newer maintenance-free bearing design while maintaining the same physical dimensions and performance specs, making it a drop-in replacement.
Can this pump be used for potable water systems?
No, this specific model features a cast iron body, which is intended for closed-loop hydronic heating and cooling. For potable water applications, a bronze or stainless steel model is required.
What are the electrical requirements for the H51BF?
The pump operates on a standard 115Vac, single-phase power supply at 60Hz. It is designed for easy integration into most residential and light commercial electrical systems.
