Armstrong 410133-343 Circulating Pump 704T Bronze Impeller

Large-scale heating systems need Armstrong 410133-343 704T for three-phase commercial HVAC and secondary-loop circulation. Its 1/6 HP cast iron pump uses a bronze non-ferrous impeller, modular three-piece shaft design, bronze sleeve, and oil-lubricated sleeve bearings. Confirm the 208 to 230 or 460 V supply, 125 PSI pressure limit, bearing lubrication, and system curve before startup.

The Armstrong Series 700 704T uses a cast iron body with bronze-fitted hydraulic components and a three-piece modular shaft. Its oil-lubricated sleeve bearings require the specified service practice, while the three-phase motor accepts 208 to 230 or 460 V configuration. Verified data does not include GPM, maximum head, amp draw, RPM, seal material, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so confirm the complete pump selection.
