Grundfos MAGNA3 N Stainless Steel Permanent Magnet Variable Frequency Shielded Circulation Pump

According to the provided technical manual, the MAGNA3 N series stainless steel permanent magnet variable frequency shielded circulation pump

1.Core Functions

AUTOADAPT Intelligent Adaptation: Automatically adjusts operating parameters according to system characteristics to optimize energy consumption (factory default mode).
FLOWLIMIT: Allows setting a maximum traffic limit (25%-90% Qmax) to prevent system overload.
FLOWADAPT Adaptive Traffic: Combines AUTOADAPT and FLOWLIMIT to dynamically balance traffic and load demands.
Multiple control modes: Supports proportional pressure, constant pressure, constant temperature, temperature difference control, constant flow, and fixed curve operation.

2.Sensors and Monitoring

Built-in high-precision sensors: Integrated differential pressure and temperature sensors for real-time monitoring of system status.
Heat energy metering: Calculates heat energy consumption based on flow rate and temperature, with an accuracy of ±5% (requires external temperature sensor).
3D Operation Log: Stores historical operating data, supporting performance analysis and troubleshooting.

3.Energy Efficiency and Reliability

Permanent Magnet Motor Technology: 4-pole synchronous permanent magnet motor, with higher efficiency than traditional asynchronous motors, equipped with an integrated frequency converter.

Mechanical seal-free design: It uses gasket sealing, which is maintenance-free and has no risk of leakage. Wide temperature range operation: liquid temperature range -10 to +110°C, stainless steel pump housing is corrosion resistant and suitable for harsh environments such as domestic hot water.

4.Intelligent Interaction and Expansion

Grundfos GO Remote Wireless Control: Connects to a mobile app via Bluetooth for remote monitoring and parameter adjustment.

Multi-pump collaboration: Supports wireless GENIair communication to enable alternating, standby, or cascaded operation (requires pumps of the same model).

CIM module expansion: Optional communication modules (such as PROFIBUS, Modbus, etc.) can be added to connect to the building management system.

5.Structural Design

Stainless steel pump casing (Model N): Meets drinking water standards and has strong corrosion resistance.

Compact sealing structure: The motor and pump body are integrated into one design, with an IPX4D protection rating. Low-noise operation: Sound pressure levels as low as 39 dB(A), depending on the model and load.

6.Application Suitability

Heating/cooling systems: Supports various applications such as solar heating, ground-source heat pumps, and air conditioning.
Flexible installation: Can be installed horizontally or vertically; features flange or threaded connections (PN10/16 standards).

Note: The above features apply generally to both cast iron and stainless steel versions; stainless steel models (N) offer enhanced corrosion resistance and meet specific hygiene requirements.
