Armstrong Fluid Technology 110223-310 Pump

The Armstrong Fluid Technology 110223-310 Pump, also known as the Model Astro 225SSU, is a high-performance stainless steel circulator pump engineered for efficiency in potable water and hydronic heating systems. Featuring a versatile three-speed motor, this hydronic heating pump allows for field-adjustable flow rates to match specific system demands, reducing energy consumption and operational noise. Operating at 115Vac with a low 0.69 full load amps and 83 watts, it provides a cost-effective solution for residential and light commercial water circulation. The maintenance-free design utilizes ceramic bearings and a Noryl impeller to ensure long-term reliability without the need for manual lubrication. This model is specifically designed for use with union fittings (sold separately) and includes a pre-installed, removable high-flow check valve to prevent backflow and simplify the installation process in tight spaces.
