Armstrong 410134-240 Circulating Pump 706S Bronze Impeller

Circulate residential HVAC water with Armstrong 410134-240 706S, a 1/3 HP single-phase pump with a bronze impeller and approximately 23 feet of maximum head. The 115 V configuration fits many residential service setups, while the universal two-bolt flange pattern gives installers a clear connection detail to verify during replacement. Check the pump curve before installation. Maximum head alone does not confirm the required flow at the system duty point.

The cast-iron body carries an alloy-steel shaft with a bronze sleeve and drives the specified bronze impeller from a 115 V single-phase motor. The pump is intended for higher-flow residential HVAC service and systems needing erosion resistance, but the supplied data does not state GPM, pressure, amp draw, seal type, self-priming capability, physical dimensions, or unit weight. Verify flange spacing, electrical protection, and suction conditions before startup.

Why the Armstrong 410134-240 706S Stands Out

The 706S Bronze Fitted model pairs a residential 115 V electrical setup with identified bronze and alloy-steel wear components. The universal two-bolt pattern also gives installers a practical connection point to compare before removing the existing circulator.

- Build: Cast iron, bronze, and alloy steel provide specified material selections for hydronic service; enclosure rating and mounting details were not supplied.
- Value: Confirming required flow against the approximately 23-foot head rating can help prevent an undersized replacement and another service visit.
- Audience: A practical fit for residential HVAC contractors, boiler technicians, hydronic installers, and maintenance teams.

Applications & Use Cases

Apply the Armstrong 410134-240 706S to residential HVAC zones, boiler branches, radiant-heating circuits, and higher-flow hydronic distribution systems requiring 115 V power. The universal two-bolt flange pattern supports compatible layouts, but exact physical dimensions, unit weight, and port-to-port reach were not included. Verify flange spacing, valve access, pipe alignment, and mounting support before purchase.

Warranty & Support

- 1-Year Limited Warranty, subject to Armstrong’s applicable terms, registration requirements, installation conditions, and authorized service procedures.
- Verify model 706S Bronze Fitted and SKU 410134-240 against the existing nameplate and flange pattern.

Fill and purge the system, clean the inlet strainer, inspect the shaft area for seal leakage, and confirm the 115 V circuit has suitable motor protection. Watch for air noise, vibration, and overheating during commissioning, then compare operating conditions with the approved hydronic design.
