- Flow Capacity: Up to 30 GPM at high speed, maintaining steady circulation.
- Power Consumption: Efficient 1/6 HP rating reduces overall energy use.
- Noise Level: Operates below 50 dB(A) for quiet environments.
- Reliability: Robust bearings and sealed housing extend service life.
⚠️Application Profile: Ideal for boiler feedwater pumps, condenser water recirculation, HVAC chiller loops, and small‑capacity hydronic heating systems.
