Engineered to sustain consistent water circulation in low‑voltage Armstrong S‑45 boiler systems, this less‑volute pump delivers optimal heat transfer while curbing vibration and noise. The **110116MF-203** serves as a direct replacement, matching the original design and performance criteria.
The pump utilizes a reduced‑volume volute housing that minimizes hydraulic turbulence, allowing the motor to operate efficiently at lower power levels. Its sealed bearings and corrosion‑resistant finish prolong service life in demanding boiler environments.
Key System Performance Baselines:
- Rated Flow: matches original S‑45 LV pump specifications for reliable circulation.
- Maximum Head: engineered to meet standard boiler pressure requirements.
- Power Consumption: low‑voltage design reduces energy usage.
- Operating Temperature Range: suitable for typical boiler operating conditions.
⚠️ Application Profile: Ideal for retrofit of Armstrong S‑45 LV boilers, commercial heating loops, and any system requiring a reliable less‑volute pump replacement.
