Armstrong Fluid Technology 116432MF-133 Pump
The Armstrong Fluid Technology 116432MF-133 Pump (Model H51AB) is a high-performance 1/4 HP circulator pump engineered for precision in hydronic heating, cooling, and domestic water systems. This single-phase, 115Vac unit features a lead-free bronze body and a non-ferrous impeller, ensuring superior corrosion resistance and longevity in demanding HVACR environments. Designed as a direct replacement for 116432-133 and 116432LF-133, this centrifugal pump utilizes a maintenance-free design with permanently lubricated bearings, eliminating the need for manual oiling. The three-piece design with a radially-split body allows for easy in-line servicing without disturbing piping connections. Equipped with built-in thermal overload protection and a positive mechanical ARMseal, the 116432MF-133 provides quiet, reliable fluid handling for 1 inch flange applications. Whether used for boiler feed systems or general circulation, this Armstrong pump delivers efficient HVAC water circulation with a maximum flow of 45 GPM and a max head of 24 feet.
Key Benefits
- Enhanced Durability: The lead-free bronze construction resists corrosion, making it ideal for domestic water systems.
- Reduced Maintenance: Features a maintenance-free bearing assembly with no lubrication required for life.
- Simplified Service: The radially-split body and modular construction allow technicians to service the pump while it remains in-line.
- Operational Safety: Includes built-in thermal overload protection to prevent motor damage during electrical surges or overheating.
- Broad Compatibility: Functions as a seamless direct replacement for older 116432-133 and 116432LF-133 models.
Common Questions
Is this pump suitable for potable water?
Yes, the lead-free bronze body ensures compliance with safety standards for domestic and potable water applications.
Does this model require regular oiling?
No, the 116432MF-133 is a maintenance-free model with factory-lubricated bearings that do not require additional oil.
Can I replace a cast iron pump with this bronze version?
While the dimensions may match, bronze pumps are specifically required for open loop and domestic water systems to prevent rusting, whereas cast iron is typically reserved for closed-loop heating.
