The MAGNA1 combines rugged reliability with intelligent engineering to provide a "set-it-and-forget-it" solution for commercial hydronic systems.

Optimize Your Performance

• Intelligent Control Modes: Nine distinct settings allow you to tailor the pump to your specific system demands, including three settings each for Proportional Pressure, Constant Pressure, and Fixed Speed.

• The "Grundfos Eye": Get instant visual feedback on your pump's health. The intuitive light indicator shows at a glance whether the pump is running perfectly, needs attention, or has triggered an alarm.

Maximum Efficiency & Durability

• Cut Energy Costs by 50%: The advanced electronically commutated motor (ECM) uses less than half the electricity of a standard pump motor, significantly lowering your utility bills.

• Built for Tough Environments: Featuring a Magnetite-resistant design and 360 mNm starting torque, this pump easily clears sediment and system debris that would stall lesser models.

• Maintenance-Free Operation: The wet rotor design ensures whisper-quiet performance and eliminates the need for routine servicing.

Simplified Installation

• All-in-One Design: The integrated pump, motor, and control system reduce complexity and installation time. Plus, no external motor protection is required.

• Ready to Go: Cast-iron models come standard with insulating shells to prevent heat loss and protect the unit immediately.

• Material Versatility: Available in both Cast Iron and Stainless Steel to suit any heating or cooling application.

Technical Summary

• Motor Type: High-efficiency ECM

• Starting Torque: 360 mNm (Debris clearing)

• Installation: Tool-free electrical plug options and compact design.
