Wet rotor circulation pump MAGNA3 32-80 F 220 1x230V PN6/10 98333874

Canless circulation pump – an effective solution for your installation

The Grundfos MAGNA3 32-80 F circulation pump is an advanced device designed to force liquid circulation in heating, air conditioning and domestic hot water systems. The wet-rotor design and lack of mechanical seals minimize the risk of failure and ensure long-lasting, maintenance-free operation. This pump is ideal for both new and modernized installations, offering optimal efficiency and low operating costs.

Design and application

The MAGNA3 32-80 F pump is characterized by a solid construction with a cast iron (GG 20) housing, which provides high corrosion resistance and long service life. The impeller made of carbon fiber reinforced composite and the bearing plate made of stainless steel further increase the durability of the device. Thanks to the built-in controller and control panel with a TFT display, the pump offers a wide range of adjustment and monitoring possibilities. The ability to communicate via protocols such as Modbus RTU, PROFIBUS, BACnet MS/TP or LON/LONWorks allows the pump to be integrated with building automation systems. The pump is adapted to work in ambient temperature from 0 to 40°C and in the liquid temperature range from -10 to 110°C.

Advantages and benefits

• High energy efficiency (EEI 0.18): This means significant energy savings compared to older pump models.
• Built-in controller: Allows precise adjustment of the pump's operation to the current needs of the installation, which translates into user comfort and reduced costs.
• Wide communication possibilities: Integration with BMS (Building Management System) allows for remote monitoring and control of the pump's operation.
• Durable construction: Cast iron housing and high-quality impeller materials ensure long service life.
• Low failure rate: Lack of mechanical seals eliminates the risk of leaks and downtime.
• Easy installation and operation: Compact dimensions (connection length 220 mm) facilitate installation, and the intuitive control panel ensures simple operation.
• AUTOADAPT, FLOWADAPT and FLOWLIMIT functions: Automatically adjust the pump's operation to changing conditions in the installation, eliminating the need for throttling valves.
• 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals: Allow connection of the pump to external control and monitoring systems.

The MAGNA3 pump is an investment in comfort, reliability and energy savings for any heating or air conditioning system. Its advanced functions and solid construction guarantee trouble-free operation for many years.
