GRUNDFOS Grundfos Flange Pump MAGNA3 D 32-120 F 220 1x230V PN6/10 No. 97924454 – 97924454

High-efficiency circulation twin pump MAGNA3 D High-efficiency wet runner twin pump made of grey cast iron with permanent magnet motor (ECM technology) and integrated electronic power adjustment through stepless speed change for pumping clean, low-viscosity media, without solid or long-fibred components that would chemically or mechanically attack the pump. Up to and including DN 65 with combination flanges PN 06/10. Twin pump with pump housing made of grey cast iron and spring-loaded change-over flap for silent change-over between the pump heads. Synchronous motors with ECM technology and highest efficiencies, high starting torque and integrated full motor protection. Functions and features: - EEI <= 0.20 Best in Class - Operating modes: standby, alternating operation and efficiency-optimized peak load connection, i.e. parallel operation - Low warehousing due to combination flanges PN 06/10, also available as PN 16 version - Cataphoretic coating for highest corrosion resistance and longevity - AutoAdapt function finds the optimal setting through self-adapting characteristic curve - FlowLimit function for limiting the max. flow rate in all control types, including in AutoAdapt = FlowAdapt function - Further control/setting types: Proportional pressure control Constant pressure control Constant temperature control Constant characteristic curve - Media temperatures continuously -10C to +110C independent of ambient temperature - Automatic night setback for further energy saving - Easiest pump head installation with clamp band and profile clamp - Commissioning via virtual commissioning assistant - 2 relay outputs for operating and fault messages - Plug-in modules in the terminal box for connection to building management systems available as accessories. The following protocols are available: GeniBus, ModBus, LonWorks, ProfiBus, BacNet. - Wireless communication via radio to Grundfos GO remote control and diagnostic device as well as between the two pump heads -> No wiring effort - Intuitive user interface with TFT monitor and status indicator for operation, warning, alarm - Operation optimization through continuous recording and storage of all operating points and conditions - Heat quantity and power detection possible via external temperature sensor (accessory) - Context-related operating and setting assistant - Continuous storage of warnings and alarms with date and time - Split casing made of composite material - Made in Germany
