Designed to circulate water efficiently within Armstrong S‑55 LV boilers, this pump‑less volute ensures steady flow and reduced cavitation. The **110116MF-306** part integrates seamlessly with the S‑55 LV model, delivering reliable performance in demanding heating applications.
The pump‑less volute operates by eliminating turbulent eddies inside the pump housing, providing a smoother hydraulic path that improves overall system efficiency. Its streamlined geometry reduces vibration and extends the lifespan of both the pump and associated components.
Key System Performance Baselines:
- Flow Rate: Maintains up to 5 GPM at 0‑30 psi, ensuring consistent water movement.
- Operating Pressure: Supports system pressures from 0 to 30 psi for versatile boiler configurations.
- Temperature Range: Reliable operation from ‑20 °F to 212 °F.
- Noise Reduction: Up to 3 dB quieter than standard volutes, minimizing acoustic impact.
⚠️ Application Profile: Ideal for commercial boiler rooms, residential S‑55 LV heating loops, Raypak boiler retrofits, and any hydronic system requiring a reliable pump‑less volute.
