MAGNA3 Variable Speed Circulator Pump
MAGNA3 Delivers Unequaled Efficiency in Circulator Pumps
The MAGNA3 circulator is one of the most innovative members of the Grundfos family of high-quality pumps. MAGNA3 pumps make up a broad range of small, medium and large circulator pumps. Every MAGNA3 pump is fitted with communication equipment and motors with electronic speed control. All motors are permanent magnet and compact stator motor technology.
With a MAGNA3, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT.
The MAGNA3 analyzes the system, finds the optimum setting and then continuously adjust its operation to changes in demand. The result is optimum comfort and minimum energy consumption. MAGNA3 pumps are extremely flexible and reliable, have low noise levels, long life and no maintenance requirements. They are fitted with wireless communication through the Grundfos GO system and can offer external control and monitoring via expansion modules.
Built for Building Management
Optional CIM modules support all common fieldbus standards, making the pump the perfect addition to any BMS system.
Heat Energy Meter
The MAGNA3 features a built-in heat energy meter that can monitor system heat energy distribution and consumption in order to avoid excessive energy bills caused by system imbalances. The heat energy meter has an accuracy of +/-1% to +/-10%, depending on the duty point, and will save you the cost of installing a separate energy metering device within your system.
No Pump Throttling Valves
The new FLOWLIMIT function and FLOWADAPT control mode allow you to set a maximum flow limit for the pump. The pump continuously monitors the flow rate to ensure the desired maximum flow is not exceeded. This eliminates the need for pump throttling valves and hereby improves the system's overall energy-efficiency. To meet system flow limitations, the pump will adjust its performance to a given setpoint, which dramatically cuts energy consumption.
Wireless Communication Between Two Single Pumps
MAGNA3 is supplied with wireless technology which enables it to connect to another identical pump. using the built-in wizard, connection to a parallel coupled pump is quick and easily obtained. The two pumps are now controlled jointly in either cascade mode, alternating mode or pump back-up mode.
The innovative 3D work log and duty Point over Time curve make optimization simple and accurate. The two new features give you the details of the pump's performance since the day it was installed as well as the details of its operating conditions, such as average temperature and power consumption. based on this, it is easy to find the optimal replacement pump, perfect optimization plan or carry out troubleshooting.
