MAGNA1 32-60 N Circulating Pump

The Grundfos MAGNA1 32-60 N circulating pump is a versatile and efficient option for the recirculation of domestic hot water and other heating applications. Made from stainless steel, it is particularly suitable for environments that require high corrosion resistance, such as hot water systems. This model stands out for its compact design and easy installation, making it the perfect choice for replacing old circulators, improving energy performance and complying with the EuP 2015 regulations.

The MAGNA1 32-60 N is designed to meet basic control and monitoring needs, providing reliable and low-maintenance operation. Its advanced features ensure optimal operation in various applications:

• Energy efficiency: The pump has an energy efficiency index (EEI) of less than 0.23, which reduces energy consumption and improves system performance.
• Quiet operation: Designed to minimise noise, it is ideal for installations where acoustic comfort is important.
• Easy integration and control: It features start and stop functions via digital input and configurable relays for status and alarms (in NO or NC positions).

The MAGNA1 pump also includes Grundfos Eye technology, offering a visual indication of the pump's status in real-time, facilitating monitoring and maintenance.

Main technical features:

• Materials: Body made of stainless steel EN 1.4308 / ASTM A351-CF8, composite impeller.
• Maximum working pressure: 10 bar.
• Connection: Type G, 2-inch size, with a nominal pressure of PN 10.
• Liquid temperature range: -10 to 110 °C, with a typical operating temperature of 60 °C.
• Insulation and protection class: Class F (IEC 85) and protection grade X4D (IEC 34-5).

Control modes:

The MAGNA1 32-60 N offers three control modes to adjust performance according to system needs:

1. Proportional pressure control (PP1, PP2 or PP3): Adjusts pressure based on the system's flow, ideal for applications with variable demand.
2. Constant pressure control (CP1, CP2 or CP3): Maintains a fixed pressure regardless of flow, suitable for systems requiring stable pressure.
3. Constant curve control (I, II or III): Operates with a fixed flow, preferred for specific applications with constant flow.

Recommended applications:

The Grundfos MAGNA1 32-60 N pump is ideal for a variety of applications, including:

• Domestic hot water recirculation, especially in systems requiring corrosion-resistant materials.
• Heating systems and air conditioning surfaces, providing efficient and safe flow.
• Mixing loops in heating systems.
• Geothermal pumping and small chiller applications.

Electrical data:

• Maximum input power: 111 W, with a minimum consumption of 9 W.
• Nominal voltage: 1 x 230 V.
• Current consumption: 0.09 A min. / 0.9 A max.
• Mains frequency: 50/60 Hz.

Additional advantages:

• Integrated insulation casing, helping to reduce heat loss in hot water systems.
• Complies with drinking water approvals (WRAS, ACS, UBA), ensuring water quality and safety.
• Easy installation thanks to its compact design and 180 mm port-to-port connection length.

The Grundfos MAGNA1 32-60 N circulating pump is the ideal solution for those seeking an efficient and reliable option for hot water recirculation and other heating applications, combining advanced technology with a robust and adaptable design.
