Wet rotor circulation pump MAGNA3 32-100 180 1x230V PN10 97924257

Circulation pump for heating and cooling systems

The Grundfos MAGNA3 32-100 180 circulation pump is an advanced solution for heating, air conditioning and domestic hot water systems. Designed for both new and modernized buildings, it combines high energy efficiency with versatile application. Its wet-rotor design minimizes the risk of leaks and ensures quiet operation, while built-in communication functions facilitate integration with modern building management systems.

Design and operating parameters

The MAGNA3 pump is characterized by a solid construction, with a housing made of cast iron GG 20 (GJL-200), which guarantees durability and corrosion resistance. Equipped with a synchronous motor with permanent magnets, it achieves high energy efficiency - the EEI index is 0.18. The speed control is stepless, thanks to the built-in frequency converter, which allows for precise adjustment of the pump's performance to the current system needs. The maximum pump capacity is 5.65 m³/h with a head of up to 10 meters. Operation in an ambient temperature from 0 to 40°C and a maximum liquid temperature of 110°C expands its range of applications.

Functions and communication

One of the key advantages of the MAGNA3 pump is its extensive communication functionality. It supports PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP and LON/LONWorks protocols, enabling easy integration with building automation systems. Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for remote control and monitoring. A built-in potential-free switching contact increases application flexibility. The pump is equipped with an intuitive display and the ability to wirelessly connect to the Grundfos GO application, which facilitates configuration and monitoring of operating parameters. AUTOADAPT and FLOWADAPT modes automatically optimize pump operation, reducing energy costs and eliminating the need for throttling valves.
