Grundfos MAGNA3 40-80 F Cast Iron Flanged Circulator Pump (115V)
Engineered for mid-sized commercial hydronic heating and cooling systems, the Grundfos MAGNA3 40-80 F (98126800) is a high-efficiency ECM smart circulator designed for maximum performance and energy savings. Featuring a cast iron flanged body with an 8-1/2" port-to-port length, this 115V, 1/3 HP pump is the perfect drop-in replacement for legacy standard-efficiency circulators.
The MAGNA3 series is equipped with a permanent magnet (PM) motor and an integrated differential pressure and temperature sensor. It features advanced control modes like AUTOADAPT to automatically balance comfort and efficiency, along with seamless wireless connectivity via the Grundfos GO Remote app for easy setup, monitoring, and fault logging.
Key System Performance Baselines:
- AUTOADAPT & FLOWLIMIT: Automatically analyzes the heating system, finds the optimum setting, and restricts maximum flow, significantly reducing the need for pump throttling valves.
- Permanent Magnet Motor: High-efficiency ECM motor technology delivers substantial energy savings over traditional cast iron pumps.
- Integrated Sensors: Built-in differential pressure and temperature sensors eliminate the need for external wiring and sensors.
- Smart Connectivity: Fully compatible with the Grundfos GO Remote app for intuitive wireless pump control and real-time system monitoring.
⚠️ Application Profile: Ideal for commercial heating, cooling, and domestic hot water recirculation in schools, apartment buildings, and office complexes.
