Grundfos MAGNA1 25-100N Stainless DHW Pump

Tired of inconsistent hot water or noisy, inefficient heating pumps? The Grundfos MAGNA1 25-100 N is the straightforward, reliable solution you've been looking for. It’s a fit-and-forget hero for your home or light commercial project, delivering quiet, powerful performance exactly where you need it, without the fuss.

Simple, Efficient, and Built to Last

When it comes to your property’s heating or hot water, you just want things to work. That’s why we’re proud to stock the Grundfos MAGNA1. It’s the simple option for a job well done, designed for real-world performance without the complexity.

At its heart is a modern, 4-pole permanent-magnet motor, which is a fancy way of saying it’s far more efficient than older pumps. This high-efficiency design, controlled by an integrated frequency converter, ensures it meets the strict EuP 2015 regulations, leading to substantial savings on your electricity bills. The MAGNA1 truly tackles high energy costs head-on.

This pump isn't just smart; it's tough. The robust stainless steel housing makes it the perfect choice for DHW pumps, preventing corrosion and keeping your water safe. Inside, it’s just as impressive, with a carbon-fibre reinforced rotor can and a maintenance-free, canned-rotor design. This focus on durability means you can fit it and forget it, letting it do its job quietly for years.

Installation and control are a breeze. The intuitive user interface and the famous Grundfos Eye give you instant status updates. For more advanced setups, a digital start/stop input and fault relay output provide essential monitoring capabilities for peace of mind. Plus, it communicates wirelessly with the Grundfos GO Remote app, bringing modern convenience to a classic workhorse.

Its versatility makes it the ideal main pump for a huge range of applications. It's perfectly at home in central heating systems, mixing loops, air-conditioning surfaces, ground-source heat pump systems, and even smaller chiller applications. For a professional finish, we recommend pairing it with quality pump valves and flanges. It even comes with insulating shells included, saving energy right from day one.
