The Grundfos Magna1 65-60 F 340 is an efficient and energy-saving solution for heating, air conditioning, and domestic hot water circulation systems. Designed for both residential and commercial applications, it ensures reliable operation and optimized operating costs. Its construction based on proven Grundfos technologies guarantees long life and minimal maintenance requirements.

Design and application

The Magna1 pump features a built-in speed controller, enabling stepless performance adjustment. This allows for precise matching of the flow rate to the current system needs, resulting in energy savings. The pump body made of cast iron GG 25 (GJL-250) provides high resistance to corrosion and mechanical damage. Flanged connections with a nominal diameter of "Other" (check the installation specifications) facilitate installation and integration with existing infrastructure. Designed to operate in ambient temperatures from 0 to 40°C and a medium temperature from -10 to 110°C, making it a universal solution for various applications.

Advantages and benefits

• High energy efficiency (EEI 0.2): Reduces electricity consumption, lowering operating costs. A low EEI index means the pump is very efficient compared to standard circulating pumps.
• Built-in speed controller: Allows precise adjustment of the pump performance to the current needs of the heating or air conditioning system.
• Solid construction: The GG 25 cast iron body guarantees durability and corrosion resistance, ensuring a long service life.
• Versatility: Suitable for use in heating, air conditioning and domestic hot water circulation systems.
• Operating monitoring: Provides continuous monitoring of the pump status, including fault detection.
• Remote control capability: Allows remote starting and stopping of the pump via a digital input – useful in BMS (Building Management System) systems.
• Potential-free switching contact: Allows integration with external control and alarm systems.
• Protection class IPX4: Provides protection against splashing water, increasing safety.

The Magna1 pump is an economical alternative to the MAGNA3 pump, offering high performance and reliability at an affordable price. Its compact dimensions (built-in length 340 mm) make it easy to install even in tight spaces. The motor power consumption is 0.365 kW with a rated current of 1.64 A and a voltage of 230 V (1 phase). The maximum head is 6 meters with a maximum flow rate of 20.94 m³/h and the head at nominal flow (BEP) is 39.89 kPa.
