Grundfos 98126836 MAGNA3 40-180 F Variable Speed Circulator Pump Cast Iron Flange Mount 208-230V 3/4 HP

The Grundfos MAGNA3 40-180 F is an energy-efficient circulator pump designed for variable-flow hydronic heating and cooling systems in residential and commercial applications. This circulator is suitable for heating systems, air-conditioning and cooling systems, domestic hot-water systems, ground source heat pump systems, and solar-heating systems.

Advanced Energy Efficiency:

With the lowest Energy Efficiency Index (EEI) in the world below 0.20, this pump can achieve energy savings of up to 75% compared to a typical installed circulator. It features a permanent magnet motor (ECM) and AUTOADAPT technology, which adjusts pump performance to meet system demands, optimizing efficiency and reducing energy consumption.

Key Features:

• Wireless monitoring via the Grundfos GO Remote app with advanced controls like AUTOADAPT and FLOWADAPT to optimize system performance
• Built-in proportional and constant pressure control for better system management
• Maintenance-free canned rotor design ensures reliability and long life
• Robust cast iron construction for long-term durability in demanding environments
• Low noise levels and minimal maintenance requirements
• TFT display for intuitive configuration of intelligent features

The MAGNA3 circulator pumps are designed for circulating liquids in heating systems with variable flows where you want to optimize the setting of the pump duty point, thus reducing energy costs. The pump is especially suitable for installation in existing systems where the differential pressure across the pump is too high in periods with reduced flow demand, as well as new systems where automatic adjustment of the head to the actual flow demand is required.
