With its unrivalled efficiency, all-encompassing range and built-in communication capabilities, the MAGNA3 is ideal for engineers and specifiers looking to create high-performance heating and cooling systems. MAGNA3 is the ideal choice for almost any building project – old or new. The pump is of the canned-rotor type, which means that 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 MAGNA3 is a pump with no maintenance requirements and with extremely low life cycle cost.

Product details
The MAGNA3 is a single-phase pump and 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 (also available in stainless steel versions)
Carbon-fibre-reinforced composite rotor can
Stainless-steel bearing plate and rotor cladding
Aluminium alloy stator housing
Air-cooled power electronics
Motor and electronic controller
The MAGNA3 incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). 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.
