Circulation pump for heating and air conditioning systems

Magna1 25-60 180 1x230V PN10 is an electronic circulation pump designed for simple heating, air conditioning and domestic hot water circulation installations. It is an economical alternative to the MAGNA3 pump, while offering high energy efficiency and easy integration with building management systems. It is a universal solution that will work well in both commercial buildings and single-family homes.

Construction and application

The pump construction is based on a solid cast iron GG 20 (GJL-200) body, which ensures durability and corrosion resistance. The impeller made of PES 30%GF material guarantees efficient liquid flow. The pump is adapted to work with water at temperatures from -10°C to 110°C, and its maximum working pressure is 10 bar. Thanks to its compact dimensions (connection length 180 mm) and standard G 1 1/2" connections, installation is simple and does not require specialized tools.

The Magna1 pump is perfect for:

• Heating in commercial and residential buildings,
• Air conditioning systems,
• Circulation of domestic hot water.

Functionality and benefits

The Magna1 pump offers a number of functions that translate into ease of use and savings:

• Built-in motor speed controller: allows smooth adjustment of the rotational speed, adapting the pump's performance to the current needs of the system. This translates into lower electricity consumption.
• Work monitoring: the pump constantly monitors its condition, including any failures, which allows for a quick response and minimization of downtime.
• Remote control: the ability to remotely start and stop the pump using a digital input facilitates integration with building automation systems.
• Dual pump function: (available in some configurations) ensures continuous system operation by automatically switching to the second pump in the event of a failure of the first.
• High energy efficiency (EEI = 0.2): the pump is characterized by a low EEI coefficient, which means minimal energy losses during operation.
• Potential-free switching contact: allows easy connection to alarm or signaling systems.

Additionally, the pump has insulation class F and protection degree IPX4, which ensures safe operation in various environmental conditions. The nominal flow rate of the pump is 4.51 m³/h, and the maximum head is 6 meters. The motor power consumption (P1) is 0.092 kW with a rated current of 0.74 A and a voltage of 230 V (single-phase).
