Armstrong 410135-303 Circulating Pump 7010T

Handle industrial HVAC circulation with Armstrong 410135-303 7010T, a 1 HP three-phase in-line pump for commercial hydronic loops and high-capacity boiler feeds. Its cast-iron body suits fixed mechanical-room installations, while the three-piece modular construction gives technicians a defined service layout. Remove air from the loop before energizing. Trapped air can cause unstable flow, shaft-seal wear, and vibration that travels into connected piping.

The 1 HP motor operates on 208–230/460 V three-phase power at 1725 RPM. Oil-lubricated sleeve bearings require the maintenance attention specified for this pump style, and the mechanical ceramic/carbon seal contains fluid at the shaft. The supplied data does not include GPM, maximum head, working pressure, amp draw, port size, or self-priming capability, so select the pump from the approved system curve and confirm flooded-suction conditions.

Why the Armstrong 410135-303 7010T Stands Out

The 7010T is made for serviceable commercial installations rather than light residential circulation. Its modular body gives maintenance crews easier access to the pump assembly, while the cast-iron casing fits many fixed HVAC and boiler-room applications.

- Build: Cast iron and three-piece construction suit stationary hydronic service; enclosure rating and corrosion-protection details were not supplied.
- Value: Correct 1 HP sizing and scheduled bearing lubrication can help limit circulation complaints, seal replacement, and unplanned shutdowns.
- Audience: A practical match for industrial HVAC contractors, boiler technicians, facility engineers, and commercial maintenance teams.

Applications & Use Cases

Install the Armstrong 410135-303 7010T in industrial HVAC loops, high-capacity boiler feeds, air-handler circuits, and mechanical-room distribution headers. Physical dimensions, unit weight, suction and discharge port size, and port-to-port reach were not included in the supplied product data. Confirm pipe centerlines, connection details, lifting access, and service clearance before installation.

Warranty & Support

- 1-Year Limited Warranty, subject to Armstrong’s applicable terms, registration requirements, installation conditions, and authorized service procedures.
- Match model 7010T and SKU 410135-303 to the existing pump nameplate before purchase.

Prime and purge the loop, verify bearing-oil service requirements, inspect the ceramic/carbon seal for weeping, and check the motor for correct phase and voltage. Confirm overload protection and monitor vibration during commissioning, especially when connecting to older piping.
