Armstrong Fluid Technology 182212-841 Pump

The Armstrong Fluid Technology 182212-841 is a high-performance Cast Iron Maintenance-Free High Efficiency Circulator Pump (Model E12.2) engineered for demand-heavy hydronic heating systems. As a direct replacement for 180210-841, this unit offers a seamless upgrade path with its compact design and universal flange compatibility, fitting 3/4", 1", 1 1/4", or 1 1/2" connections. Powered by a 2/5HP single phase motor operating at 3300 RPM on 120Vac, it delivers superior wire-to-water efficiency that is up to 41% better than competitive models. This centrifugal pump is built for durability, featuring a stainless steel shaft and a bellows-style mechanical seal with silicon carbide wear surfaces to prevent leakage. Whether utilized for radiant heating, snow-melt installations, or domestic hot water recirculation, the E.2 series provides whisper-quiet operation and long-lasting reliability without the need for periodic lubrication.

• Maintenance-Free Reliability: Features permanently lubricated bearings and a dry motor design, eliminating the need for manual oiling.
• Enhanced Durability: Equipped with a large stainless steel shaft and a redesigned water slinger to protect electrical components from water intrusion.
• High Precision Performance: Includes a bellows-style mechanical seal with silicon carbide wear surfaces for superior protection against leaks.
• Versatile Compatibility: Designed to fit multiple flange sizes (3/4" to 1 1/2"), making it an ideal choice for varying residential and light commercial pipe dimensions.
• Easy Serviceability: The compact, lightweight design allows for quick installation in tight spaces, and the mechanical seal can be serviced or replaced in minutes.

• Is the 182212-841 compatible with my older 180210-841 pump? Yes, the 182212-841 is the official direct replacement for the discontinued 180210-841 model, sharing the same footprint and performance specs.
• Does this pump include flanges? No, flanges are sold separately to allow for custom sizing to your specific pipe diameter (3/4", 1", 1 1/4", or 1 1/2").
• Can this be used for potable water systems? No, this cast iron model is intended for closed-loop hydronic heating; for potable water applications, a bronze or stainless steel version is required.
