ARMSTRONG

ARMSTRONG is a manufacturer of fluid-handling equipment, with a product line centered on circulator pumps, in-line circulating pumps, and the associated components required for installation and maintenance in hydronic systems. The company's catalog includes general-purpose inline circulator pumps, OEM replacement motors, bearing assemblies, flange hardware kits, and standard flanges. These products are designed for use in potable water systems, heating and cooling loops, and other closed-loop fluid transfer applications where reliable circulation is required. ARMSTRONG components are specified by plant engineers and maintenance managers for their dimensional compatibility with existing pump models, such as the S&H 4-Series, H-32, and E7.2HT series. The product range covers motors with 48Z frame designations, single-phase 120V AC operation, and horsepower ratings such as 1/6 hp and 1/4 hp. Flanges are available in sizes including 1 1/2 in and 2 in NPT, constructed from stainless steel with EPDM gaskets, and are supplied as part of flange hardware kits that include steel bolts and rubber gaskets. Bearing assemblies for in-line circulating pumps are offered as seal-bearing units compatible with specific series like the H-32. 3G Electric stocks over 158 SKUs of ARMSTRONG products, providing datasheets and logistics support for global procurement. The inventory includes OEM motors, standard flanges, flange hardware kits, bearing assemblies, unions, and general-purpose inline circulator pumps. Each item is identified by manufacturer part numbers and is cross-referenced for compatibility with Grainger part numbers where applicable. For technical buyers, ARMSTRONG components are specified by their build standards—cast iron volutes, stainless steel flanges, and EPDM gaskets—and by performance parameters such as flow rate (up to 38 gpm) and maximum head (34 ft). The product line supports both new installations and retrofits, with replacement parts designed to match existing pump configurations. 3G Electric's role is to supply these components with accurate specifications and global shipping, enabling engineers and procurement specialists to source ARMSTRONG parts without relying on local distributors.
