Armstrong H-63-3 Series Cast Iron Centrifugal Pump 1/2HP 3 Phase

Description

Support cooling-tower circulation with Armstrong 116467-136A H-63-3, a 1/2 HP three-phase cast-iron pump for industrial HVAC systems. Its 208–230/460 V motor, 2-inch flanged connection, and flexible coupler suit secondary cooling loops where the piping layout and motor service must be coordinated. The 225°F temperature limit applies to compatible systems. Verify phase rotation and the actual system curve before installation.

The pump uses an ODP motor and Series 1060 standard configuration with a Sealed Bearing Assembly. The supplied data does not state flow, head, amp draw, dimensions, weight, shaft material, or seal material. Manufacturer reference data for Series 1060 standard circulators identifies sleeve-oil-lubricated bearing construction, so confirm the exact bearing arrangement and maintenance requirements before startup.

Key Features & Benefits

• 1/2 HP Motor: Supports three-phase industrial HVAC and cooling-tower circulation.
• 208–230/460 V Service: Fits compatible commercial electrical systems with verified phase rotation.
• Cast-Iron Body: Provides the specified casing material for closed-loop HVAC service.

• Build: Cast iron, ODP motor, flexible coupler, 2-inch flange, and Series 1060 construction define the supplied pump.
• Value: Confirming bearing service requirements can prevent missed lubrication and avoidable downtime.
• Audience: Suited to industrial HVAC contractors, cooling-tower technicians, facility engineers, and maintenance teams.

Applications & Use Cases

Use Armstrong 116467-136A H-63-3 for three-phase industrial HVAC, cooling-tower secondary loops, and compatible 2-inch flanged systems. The supplied data does not provide overall dimensions, unit weight, or port-to-port reach, so verify pipe support, flange alignment, coupling access, bearing service space, and motor clearance before installation.

Warranty & Support

• Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with Armstrong or the seller.
• Match SKU 116467-136A, H-63-3 model, horsepower, phase, voltage, flange size, coupler, and bearing arrangement before ordering.

Fill and purge the loop, inspect the coupler and seal area, verify phase rotation, and follow the confirmed bearing-lubrication requirements. Monitor vibration, temperature, noise, and leakage during commissioning.
