Grundfos - Magna3 25-100 Variable Speed Circulator - 180mm - 240V - MAG3-97924247

Setting the MAGNA3 is simple – just install the pump and leave it on the AUTOADAPT setting, the pump will then analyse the heating system demands and find the optimum setting. It will then continuously adjust its operation to deal with changing system demands.

Characteristic incorporates:

• AUTOADAPT.
• FLOWADAPT and FLOWLIMIT (more than a pump function as it reduces the need for pump throttling valves).
• Proportional-pressure control.
• Fixed-pressure setpoint pressure control.
• Constant-temperature control.
• Constant-curve duty.
• Max. or min. curve duty.
• Automatic Night Setback.
• No external motor overload 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.

Real-world product applications

• Boosting water pressure to multiple outlets in a building
• Maintaining stable pressure where demand varies
• Supplying water from storage tanks to distribution pipework
• Supporting general water supply and transfer systems
• Assisting with pressure control in utility installations
