Description
The Armstrong Fluid Technology 116491-136A (Model H65BF) is a 1 HP commercial-grade circulator pump engineered for dependable performance in hydronic heating and cooling systems. Built to operate on 208-230/460 VAC three-phase power, this pump combines a heavy-duty cast iron body with a corrosion-resistant non-ferrous impeller — delivering consistent fluid movement and long-term reliability in demanding closed-loop HVAC environments.
