Grundfos MAGNA3 50-120 GF N is a feature-rich, stainless steel high-efficiency variable speed circulator pump designed for wide range of large residential, commercial and industrial heating, cooling and domestic water recirculating applications.
Features:
- Wide range of modes to choose from: proportional pressure (adapts to flow demand), constant pressure (keeps pressure consistent), constant temperature, differential temperature (constant temperature drop), constant curve (constant flow and constant head w/ adjusted duty point), constant flow (maintains flow independently of the head), AUTOAdapt, FLOWAdapt, and FLOWLimit (ensures that the set rated flow is never exceeded)
- (3) wireless communication modes between two single MAGNA3 pumps: alternating (one pump operates at a time, changing to the other depending on time or energy performance), backup (one main + one backup which occasionally engages to prevent seizing up), and cascade operation (both pumps automatically switch on/off, adapting to the current system changes/demands)
- Optional Grundfos GO app connectivity (via Bluetooth) for set-up/scheduling, diagnostics, and performance data
- AUTOAdapt (default factory setting) automatically adjusts the pump performance to the size of the system and load over time
- FLOWAdapt combines FLOWLimit & AUTOAdapt features, automatically setting the most efficient mode, while not overriding the flow limit
- Highest efficiency rating on the market
- Built-in energy meter monitors energy distribution and consumption
- Grundfos Eye LED displays system status for easy troubleshooting
- Application wizard interface helps to identify the best-suited control mode
- Automatic air-cooling of the system prevents condensation
