Armstrong 410135-302 Circulating Pump 709T

High-demand industrial heating uses Armstrong 410135-302 709T for commercial boiler plants and three-phase circulation. Its 3/4 HP motor accepts 208 to 230 or 460 V, while the heavy-duty three-piece body, curve-specific impeller, and multi-material shaft sleeve support demanding service. Confirm the Buna-N, ceramic, and carbon seal materials, phase rotation, system curve, and motor protection before startup.

The Armstrong Series 700 709T uses a heavy-duty three-piece design with an impeller trimmed for a specific performance curve. Its stainless steel or bronze shaft sleeve supports shaft protection, while verified data does not include GPM, maximum head, amp draw, RPM, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the boiler-plant duty point before installation.
