Armstrong 116479-136A H-64-3 Cast Iron Pump 3/4HP 3PH

Circulate closed-loop HVAC water with Armstrong 116479-136A H-64-3, a 3/4 HP three-phase Series 1060 pump for industrial hydronic systems. Its cast-iron body, 1725 RPM motor, and 2-inch flanged connection suit commercial heating and cooling loops where a horizontal in-line layout is available. The 225°F maximum temperature provides a clear operating limit. Confirm the system curve and electrical protection before startup.

The maintenance-free Sealed Bearing Assembly supports the rotating components within the horizontal in-line arrangement. The 208–230/460 V motor requires phase verification and correct rotation before commissioning. Flow, head, amp draw, dimensions, weight, seal material, and port-to-port reach were not supplied, so check the current submittal before installation.
