The Armstrong S-55-1 AB all‑bronze centrifugal pump ensures steady water circulation in residential and commercial hydronic heating systems. Engineered for durability, the 106284MF-133 model (S‑55‑1 AB) provides reliable 1/2 hp performance that integrates seamlessly with existing loops.
This pump uses a closed‑impeller design and bronze housing to minimize corrosion while maintaining high efficiency. Water enters the inlet, the impeller accelerates flow, and the centrifugal force moves water to the discharge, delivering consistent pressure across the system.
Key System Performance Baselines:
- Flow Capacity: Up to 12 GPM at 30 psi.
- Power Consumption: 1/2 hp motor optimized for energy savings.
- Material Longevity: All‑bronze construction resists corrosion for extended service life.
- Quiet Operation: Low‑vibration design reduces noise levels.
🚨 Application Profile: Ideal for boiler condensate recirculation, hot‑water baseboard heating loops, solar thermal pre‑heat circuits, and district‑energy hydronic networks.
