Grundfos 98126832 MAGNA3 40-120 GF Variable Speed Circulator Pump 208-230V 1/2 HP Cast Iron

The Grundfos 98126832 MAGNA3 40-120 GF is a multi-mode, feature-packed, high-efficiency circulator pump for residential, commercial and industrial heating and cooling applications. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, MAGNA3 is ideal for engineers and specifiers looking to create high-performance heating and cooling systems.

Key Features:

• Incorporates a 4-pole synchronous, permanent-magnet motor (PM motor) characterized by higher efficiency than a conventional asynchronous squirrel-cage motor
• AUTOADAPT automatically adjusts pump operation to meet system demands and reduces energy consumption by up to 85%
• FLOWLimit restricts maximum flow and reduces the need for pump throttling valves
• Built-in differential-pressure and temperature sensor
• Includes built-in components: Flowmeter, Pressure Gauges, BTU meter, and Temperature Sensor
• Features an intuitive display and allows wireless connection with the Grundfos GO Remote app for advanced reporting and monitoring
• Supports fieldbus by optional CIM modules and has a TFT display for intuitive configuration

Technical Specifications:

• Rated flow: 55.5 GPM, Rated head: 25.59 ft, Maximum head: 39.37 ft
• Power input: 16 to 422 W, Current: 0.19 to 1.89 A, Frequency: 60 Hz
• Voltage: 1 x 208-230V, Maximum operating pressure: 174 psi
• Pump housing: Cast Iron
• Ambient temperature: 32 to 104°F
• Weight: 31 lbs

Applications:

• Heating & cooling systems, Ground source heat pump systems, Hydronic venting
• Chilled water, Snow melt, Hot water recirculation, BTU meter

The pump is maintenance-free due to the canned-rotor type design, which means pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. Wet rotor design allows for maintenance free and quiet operation.
