Armstrong 110223-320 - Astro 280CI Cast Iron Circulator Pump

Reliable circulation of heated water is critical for maintaining steady indoor temperatures and efficient boiler operation. The 110223-320 Armstrong Astro 280CI cast‑iron circulating pump delivers robust flow while resisting corrosion and wear.

Featuring a cast‑iron housing and a sealed‑bearing motor, the pump moves water through a single‑stage impeller that generates consistent pressure across a range of system demands. Its low‑speed design reduces noise and energy consumption.

Key System Performance Baselines:

• Flow Capacity: Provides ample GPM flow for typical residential and light‑commercial loops.
• Maximum Head: Handles system pressures up to industry‑standard limits for reliable circulation.
• Motor Power: Optimized low‑watt consumption for energy‑efficient operation.
• Operating Temperature: Designed for continuous use within standard hydronic temperature ranges.

⚠️ Application Profile: Ideal for residential boiler loops, small commercial heating systems, domestic hot water recirculation, and mixed‑use buildings requiring durable, low‑noise pump performance.
