Armstrong Fluid Technology 182202-652 Pump

The Armstrong Fluid Technology 182202-652 Pump (Model E11.2B) is a high-performance bronze circulator pump engineered for efficient fluid management in hydronic heating and cooling systems. This maintenance-free circulator features a 1/6HP, 120Vac single phase motor operating at 3300 RPM, delivering the power required for demanding residential and light commercial applications like radiant heating and geothermal heat pumps. As the direct updated version for the 180200-652, it incorporates a lead-free bronze body and a stainless steel shaft for enhanced durability and corrosion resistance. The design includes permanently lubricated bearings and a bellows-style mechanical seal with silicon carbide wear surfaces to prevent leakage. Compatible with 1", 1 1/4", or 1 1/2" flanges, this high-efficiency pump ensures a low lifetime cost while maintaining a max flow (GPM) of 45 and a max head (ft) of approximately 31.9.
