Grundfos MAGNA3

Grundfos MAGNA3

Grundfos MAGNA3 is the ideal hot and cold water circulating pump, suitable for almost any construction project - whether new or retrofit. Thanks to superior energy efficiency, a wide range of applications and built-in communication functions, MAGNA3 is the perfect solution for engineers and designers creating high-efficiency heating and cooling systems.

The MAGNA3 pump is virtually maintenance-free. It has a wet impeller, which means that the motor and pump are an integrated unit with no shaft seals - only two rest seals are used, and the bearings are lubricated by pumped fluid.

The pump is equipped with intuitive display and enables wireless connection to the Grundfos GO app, which provides access to advanced monitoring and reporting. With wireless technology, MAGNA3 can connect to external controls or other MAGNA3 pumps.

Key advantages of MAGNA3:

• AUTOADAPT and FLOWADAPT for optimum efficiency without the need for throttling valves
• Built-in automation and energy reduction features
• Eliminates the need to install additional energy meters

Application:

• Mixing loops
• Heating installations
• Air conditioning and refrigeration systems
• Domestic hot water systems
• Ground source heat pump systems
• Solar heating systems

Technical characteristics:

MAGNA3 is a single-phase pump with a built-in controller and display integrated in the control box. It has a built-in differential pressure and temperature transmitter. The pump housing is available in cast iron or stainless steel, and the composite impeller box has been reinforced with carbon fiber.

Engine:

• 4-pole permanent magnet (PM) synchronous motor
• Higher efficiency than asynchronous motors
• Speed control with integrated frequency converter

Functions and modes of operation:

• Wide communication options: inputs, relays, fieldbus
• AUTOADAPT
• FLOWADAPT (reduces the need for throttling valves)
• Proportional-pressure and constant-pressure control
• Constant temperature control
• Automatic night reduction
• No need for external motor protection

In addition, the MAGNA3 is easy to install with its innovative clamp with one screw, which allows the pump head to be easily repositioned. The pump is supplied with insulation linings, and, thanks to air-cooled electronics, provides a large operating temperature range.
