Armstrong 410134-200 Circulating Pump 706S

Large residential heating uses Armstrong 410134-200 706S for apartment-building circulation and high-flow HVAC loops. Its 1/3 HP, 115 V single-phase motor operates at 1725 RPM through a cast iron body, heavy-duty spring coupler, and oil-lubricated sleeve bearing. Confirm bearing maintenance, impeller selection, system curve, motor rotation, and piping support before startup.

The Armstrong Series 700 706S uses a steel or non-ferrous composite impeller within a cast iron pump body. Its heavy-duty spring coupler transfers motor torque, while the sleeve bearing requires regular oiling during service. Verified data does not include GPM, maximum head, amp draw, seal material, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so confirm the complete pump specification before installation.
