MAGNA3 – More than a pump

With its unrivalled efficiency, all-encompassing range and built-in communication capabilities plus

functionalities replacing system components, the MAGNA3 is ideal for engineers and specifiers

looking to create high-performance systems for buildings.

This pump in the Grundfos Master Class will fit both heating and cooling applications perfectly,

making it the obvious choice for almost any building project – old or new.

The MAGNA3 is of the canned-rotor type, i.e. pump and motor form an integral unit without shaft seal

and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid.

The innovative clamp with only one screw enables easy repositioning of the pump head.

The MAGNA3 is a pump with no maintenance requirements and with extremely low Life Cycle Cost.

The pump is characterised by the following:

• controller integrated in the control box

• control panel with TFT display on the control box

• control box prepared for optional CIM modules

• built-in differential-pressure and temperature sensor

• cast-iron pump housing (depending on model)

• carbon-fiber-reinforced composite rotor can

• stainless-steel bearing plate and rotor cladding

• aluminium alloy stator housing

• air-cooled power electronics

The MAGNA3 is a single-phase pump.

Characteristic features

• AUTOADAPT.

• FLOWADAPT and FLOWLIMIT (more than a pump function as it reduces the need for pump

throttling valves).

• Proportional-pressure control.

• Constant-pressure control.

• Constant-temperature control.

• Constant-curve duty.

• Max. or min. curve duty.

• Automatic Night Setback.

• No external motor protection required.

• Insulating shells supplied with single-head pumps for heating systems.

• Large temperature range where the liquid temperature and the ambient temperature are

independent of each other.

Communication

The MAGNA3 enables communication via the following:

• wireless Grundfos GO Remote

• fieldbus communication via CIM modules

• digital inputs

• relay outputs

• analog input (more than a pump function as heat energy meter)

This motor type is characterised by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an integrated frequency converter. A differential-pressure and temperature sensor is incorporated in the pump.
