The Armstrong recirculation pump continuously moves hot water through a building’s heating loop, eliminating temperature loss and cutting down wait time for hot water at fixtures. The **110223B-140** model, Astro 220SSU050S-TA, features a stainless‑steel body and a 6‑ft line cord for easy installation in residential or light‑commercial systems.
Driven by a sealed‑bearing motor, the pump maintains a steady flow rate while automatically adjusting to system pressure changes. Its integrated aquastat ensures the pump only runs when needed, optimizing energy use and extending component life.
Key System Performance Baselines:
- Flow Rate: Provides reliable circulation up to 12 GPM at 30 psi.
- Energy Savings: Reduces pump runtime by up to 20% compared to standard units.
- Durability: Stainless‑steel construction resists corrosion for long‑term service.
- Quiet Operation: Low‑noise motor design minimizes acoustic impact.
- Compatibility: Engineered for Armstrong Astro boiler series.
⚠️ Application Profile: Ideal for residential hot‑water recirculation loops, small‑scale commercial heating systems, boiler‑to‑tank loops, and retrofit upgrades where space and efficiency are critical.
