Grundfos Magna1 25-80 circulation pump – an efficient solution for your installation. The Grundfos Magna1 25-80 is an electronic circulation pump designed for use in heating, air conditioning systems, and domestic hot water circulation. It is a user-friendly and energy-saving alternative to older generations of pumps, ideal for both installers and end-users. Thanks to the built-in motor speed controller, it provides precise flow control and optimizes energy consumption.

Construction and application

The Magna1 pump is characterized by a solid construction. The cast iron GG 20 (GJL-200) body guarantees durability and corrosion resistance. The impeller made of PES 30%GF material ensures reliable operation in various conditions. The pump's application is wide – it will work in:

• Heating of single-family homes and commercial buildings
• Air conditioning systems
• Domestic hot water circulation
• District heating and cooling networks
• Industrial heating

Connections with a diameter of 1 1/2 inch (40) with a BSPP external thread facilitate installation in existing systems. The pressure class PN 10 ensures safe operation.

Advantages of the Magna1 pump – what do you gain?

• Energy efficiency: An energy efficiency index (EEI) of 0.2 translates to lower electricity bills.
• Precise regulation: The built-in controller allows you to adjust the pump's performance to the current needs of the heating or cooling system. The speed control method is stepless, allowing optimal adaptation to working conditions.
• Reliability: The solid construction with high-quality materials guarantees a long pump life.
• Simple installation and operation: An intuitive user interface makes configuration and pump monitoring easy. The connection length of 180 mm facilitates integration with the existing installation.
• Work monitoring: The pump provides continuous monitoring of the operating status, including fault detection. It has a potential-free switching contact that can be used to remotely notify of pump problems.
• Wide temperature range: Operation in a temperature range from -10°C to 110°C allows the pump to be used in various conditions.

The Magna1 pump is an investment that quickly pays for itself thanks to energy savings and reliable operation. It is an economical alternative to more advanced models, offering excellent value for money. The motor power consumption (P1) is 0.128 kW with a rated current of 1.03 A and a voltage of 230V (single-phase). The protection class IPX4 protects the device against splashing water.
