Armstrong H-65-3 Series Cast Iron Centrifugal Pump 1HP 3 Phase

Description

Move industrial HVAC water with Armstrong 116491-136A H-65-3, a 1 HP three-phase cast-iron pump for large mechanical rooms and industrial fluid circulation. Its 208–230/460 V motor, 1725 RPM speed, approximately 5.5-inch impeller, and 50 to 55 feet of listed head provide useful references for larger hydronic systems. Confirm the actual pump curve and bearing arrangement before installation.

The alloy-steel shaft with bronze sleeve supports the rotating assembly, while the supplied heavy-duty Sealed Bearing Assembly provides the listed bearing reference. The supplied data does not state amp draw, pressure, connection size, dimensions, weight, or seal material. Verify the current Series 1060 standard-design documentation, pipe alignment, phase rotation, and service clearance before startup.
