Designed to keep hot‑water loops moving smoothly, this circulator pump provides consistent flow for residential and light‑commercial hydronic heating systems. The 106507 model, part of the Series LR‑20WR, integrates seamlessly with standard 2" NPT pipework and delivers reliable performance even under variable load conditions.
The pump utilizes a sealed‑bearing motor and a closed‑circuit impeller design that minimizes friction losses while maintaining high hydraulic efficiency. Variable speed operation (when paired with compatible controls) allows precise flow matching, reducing energy consumption and extending motor life.
Key System Performance Baselines:
- Flow Rate: Consistent delivery suited for 1‑ to 3‑ton heating loads.
- Head Capacity: Maintains pressure across typical loop lengths.
- Energy Efficiency: Optimized motor design reduces kW‑hour usage.
- Durability: Cast‑iron housing provides corrosion resistance.
⚠️ Application Profile: Ideal for residential boiler circulation, small‑commercial heat‑pump loops, domestic water recirculation, and multi‑zone radiant floor systems.
