Designed to provide robust circulation in commercial heating and cooling loops, the Armstrong S‑57‑3 cast‑iron pump ensures reliable flow. Featuring the **106285MF-136A** model designation, this 3/4 HP, 3‑phase unit delivers consistent performance for demanding applications.
The pump’s cast‑iron body houses a bronze‑fitted impeller that creates steady hydraulic pressure while minimizing wear. Its triple‑phase motor reduces vibration, and the standard 2‑in. flanged connections simplify integration into existing pipework.
Key System Performance Baselines:
- Flow Capacity: Up to 30 GPM at 30 psi, supporting medium‑size hydronic loops.
- Head Rise: Maximum of 40 ft, ensuring adequate pressure across the system.
- Power Efficiency: 3/4 HP motor meets IEC efficiency standards for reduced energy use.
- Durability: Cast‑iron construction and bronze‑fitted components resist corrosion and extend service life.
⚠️ Application Profile: Ideal for office building boilers, hotel hot‑water recirculation, industrial process heating, and large‑scale HVAC chillers.
