Description

Grundfos MAGNA3 65-120 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
Suitable for up to pumping up to 50/50 glycol & water mix solution
Insulating shell, conduit adapters, terminal glands, cable glands and gaskets included
Made in the USA
cULus, FCC Listed; NSF/ANSI 372 Listed
