Designed for residential and light‑commercial boiler systems, the Armstrong H‑53 LV pump provides reliable water circulation for efficient heating. The 110116MF-302 replacement restores the H‑53 LV pump’s less‑volute design, ensuring optimal flow and low‑noise operation.
The less‑volute impeller reduces hydraulic losses, delivering consistent pressure across a wide range of flow rates while minimizing vibration and sound. Its cast‑iron housing and stainless‑steel internals stand up to the demanding conditions of hydronic heating loops.
Key System Performance Baselines:
- Flow Capacity: Up to 10 gpm at 30 psi, supporting typical residential heating loads.
- Hydraulic Efficiency: Exceeds 70%, maximizing energy savings.
- Noise Level: Operates below 55 dB(A), ideal for quiet environments.
- Materials: Cast iron housing with stainless‑steel impeller for durability.
- Connection Size: Standard 2‑in. NPT inlet and outlet for straightforward retrofit.
⚠️ Application Profile: Suitable for Armstrong H‑53 LV boiler pumps, Raypak heating units, and other low‑volute hydronic systems in residential or small‑commercial installations.
