Technical Features:

• Pumped Liquid: Water, with a temperature range of -10 °C to 110 °C, with an optimal operating temperature of 60 °C. The density of the pumped liquid is 983.2 kg/m³.
• Manufacturing Materials: The hydraulic body is made of stainless steel, while the impeller is made of high-strength composite. The pump casing is made of stainless steel EN 1.4308, ASTM A351-CF8, ensuring excellent corrosion resistance.
• Electrical Data: With a maximum input power of 533 W and a minimum of 20.2 W, the MAGNA1 50-120 F N is highly efficient. It operates at a frequency of 50/60 Hz and requires a nominal voltage of 230 V. The current consumption varies between 0.22 A and 2.37 A, depending on operating conditions. Additionally, it has a protection rating of X4D and an insulation class of F.

Advanced Control Options:
The pump offers different control modes to suit various needs:

• Proportional Pressure Control: With three adjustable levels (PP1, PP2, PP3) to meet different flow and pressure requirements.
• Constant Pressure Control: Also adjustable in three levels (CP1, CP2, CP3), ideal for maintaining a constant pressure in the system.
• Constant Curve Control: Features three settings (I, II, III) to maintain constant performance regardless of demand.

Compatibility and Applications:
The MAGNA1 pump is designed to be compatible with a wide range of applications, such as:

• Surface heating systems.
• Mixing loops.
• Air conditioning systems and small chiller applications.
• Geothermal pumping systems.

It is also suitable for potable water installations, as it is WRAS, ACS, and UBA approved, making it suitable for use in domestic and commercial water supply systems.

Installation and Connectivity:

• The MAGNA1 50-120 F N supports ambient temperatures from 0 °C to 40 °C and can operate with a maximum working pressure of up to 10 bar.
• It features a DIN connection with a nominal size of DN 50 and a nominal pressure for the connection of PN 6/10. The port-to-port distance is 280 mm, facilitating its installation in most standard systems.

Other Key Features:
