Armstrong Fluid Technology 174036MF-113 Protection
The Armstrong Fluid Technology 174036MF-113 (Model S-45 BF) is a high-performance cast iron circulator pump designed for reliable fluid handling in commercial and residential hydronic systems. This 1/4 HP, 115Vac single phase pump is engineered with a non-ferrous impeller and a radially-split body, allowing for efficient "back pull-out" servicing without disconnecting the main piping. Built for longevity, it features permanently lubricated maintenance-free bearings and an oversized stainless steel shaft, significantly reducing operational downtime. The built-in thermal overload protection ensures the motor remains safe under demanding conditions, while the maintenance-free design eliminates the need for manual oiling. With a maximum flow rate of 109 GPM and 16 feet of head, this Armstrong S45 series pump is a preferred choice for HVAC professionals seeking a balance of power and simplicity. It is ideally suited for hydronic heating and cooling, multi-stage zoning, and general industrial service, delivering quiet and consistent performance across its entire operating range.
- Maintenance-Free Reliability: Features permanently lubricated bearings that eliminate the need for periodic lubrication and reduce service costs.
- Thermal Protection: Includes built-in thermal overload protection to prevent motor damage and ensure long-term operational safety.
- Service-Friendly Design: The 3-piece modular construction and radially-split body allow for internal maintenance while the pump remains in-line.
- Durable Construction: Built with a rugged cast iron body and a corrosion-resistant non-ferrous impeller for extended life in HVAC applications.
- High Capacity Fluid Handling: Capable of managing maximum flow rates up to 109 GPM, making it suitable for large-scale hydronic systems.
Common Questions
What size flanges are compatible with the Armstrong S45BF?This model is specifically designed to be used with 2 1/2" or 3" flanges. Please note that flanges are typically sold separately and should be selected based on your existing pipe diameter.
Can this pump be used in potable water systems?No, the 174036MF-113 features a cast iron body, which is intended for closed-loop hydronic heating and cooling systems. For domestic potable water applications, a bronze or stainless steel model is required.
Is the motor on the S45BF serviceable?Yes, the 3-piece design allows the motor and the shaft and bearing module to be removed and serviced or replaced without disturbing the piping system, which simplifies repairs.
