MAGNA1 40-40 F Circulator Pump

The Grundfos MAGNA1 40-40 F circulator pump is the perfect solution for replacing old circulators in commercial heating and air conditioning applications. This model combines basic functionality, low energy consumption, and ease of installation, making it ideal for installations requiring simple controls and monitoring. Its compliance with the EuP 2015 regulation ensures considerable energy savings, with an energy efficiency index (EEI) of less than 0.23.

Thanks to its compact and user-friendly design, the MAGNA1 40-40 F is highly suitable for commercial applications such as surface heating systems, mixing loops, and air conditioning surfaces, among others. The low noise level is another highlight, making it an efficient and discreet option for a variety of environments.

The permanent magnet rotor allows the pump to operate more efficiently, with lower electrical consumption compared to older circulators. Its start and stop are managed via a digital input, facilitating its integration into modern systems. Additionally, it features configurable status and alarm relays, adjustable to specific installation needs (NO or NC).

Among the standout features of this pump is its integrated insulation casing, which helps minimise heat loss in heating systems, and the Grundfos Eye interface, which provides visual information on the pump's operating status, allowing for quick and easy diagnostics at all times.

The MAGNA1 offers three types of control to meet the demands of different systems:

• Proportional pressure control (PP1, PP2, or PP3) adjusts the pressure proportionally to the system's needs.
• Constant pressure control (CP1, CP2, or CP3) maintains constant pressure in the system.
• Constant curve control (I, II, or III) optimises operation for applications with constant flows.

Technical specifications:

• Nominal flow: Adjustable according to the selected control mode.
• Liquid temperature range: From -10 °C to 110 °C, with an optimal operating temperature of 60 °C.
• TF Class: 110.
• Maximum working pressure: 10 bar.
• Port-to-port length: 220 mm.

Construction materials:

• Pump body: Cast iron (EN 1561 EN-GJL-250, ASTM A48-250B), highly resistant and durable.
• Impeller: High-strength composite material for greater durability.

Electrical data:

• Maximum input power: 90 W, with a minimum consumption of 12 W.
• Frequency: 50 / 60 Hz.
• Nominal voltage: 230 V.
• Protection grade: IPX4D.
• Insulation class: F.

Key advantages:

• Energy saving: With an energy efficiency index EEI < 0.23, it guarantees reduced consumption compared to older circulators.
• Quiet operation: Ideal for commercial environments where minimising noise pollution is desired.
• Easy installation: Its compact design and standard DIN connections (DN 40) facilitate replacement in existing installations without the need for major adaptations.

Additionally, the MAGNA1 40-40 F is suitable for domestic hot water applications, particularly in its stainless steel versions, making it even more versatile for a wide range of uses. Its ease of use, combined with Grundfos Eye technology, ensures that installers and operators can monitor the pump's status at all times, preventing potential failures and ensuring continuous operation.

This pump is also compatible with geothermal systems and small chillers, making it the ideal solution for projects requiring basic functionality without compromising efficiency. With a net weight of 9.57 kg and a robust design, the MAGNA1 is built to last and to deliver reliable performance over long periods of use.
