Grundfos - Magna1 25-80n 98254907 Variable Speed Circulator - 180mm - 230V - OBSOLETEMAGNA1 25-80 N
The Grundfos MAGNA1 is a circulator pump unit with permanent magnet motor and straightforward selection of pump setting. The MAGNA1 will fit both heating, cooling and domestic hot water circulation applications perfectly, making it the obvious choice for almost any building project – old or new.
The pump is a canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing.
The bearings are lubricated by the pumped liquid. A pump with no maintenance requirements and extremely low life cycle cost.
The pump has an intuitive user interface, which is especially fit for replacement of older circulators. The well-suited choice for basic performance needs in applications where system communication is not required.
Suitable for: Domestic hot water recirculation

Grundfos - Magna1 D40-60F 99221294 Twin Variable Speed Circulator - 220mm - 230V - Cast IronMAGNA1 D 40-60 F
The Grundfos MAGNA1 D circulator pump is the uncomplicated option for a job well done. With its high energy efficiency, the product complies with the EuP 2015 regulations, ensuring substantial savings on electricity. With its intuitive, user-friendly interface and maintenance-free design, MAGNA1 D is the well-suited circulator pump for basic performance needs in applications where basic system control and monitoring are desired.
With this range of circulator pumps, everything from setup to basic control and monitoring are made straightforward. The pump is maintenance-free due to the canned-rotor type design. MAGNA1 D offers peace of mind due to the security of supply obtained by having a redundant pump, resulting in improved uptime. The flow, and thereby constant comfort, is secured because of its ability to automatically switch between pump heads if one breaks down. The two pumps communicate wirelessly. MAGNA1 D offers the possibility of monitoring the pump via the fault relay output. The digital start and stop input remotely controls the pump. The pump communicates wirelessly with the Grundfos GO Remote app and can also communicate via radio. MAGNA1 D can work as the main pump in both heating and cooling applications, including:
- small chiller applications
- ground-source heat pump systems
- air-conditioning surfaces
- heating surfaces
- mixing loops
MAGNA1 D is a single-phase pump characterised by the controller and operating panel being integrated in the control box. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fibre reinforced, the bearing plate and rotor cladding are made of Stainless Steel and the stator housing is made of aluminium. The power electronics are air-cooled.
The pump incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). This motor type is characterised by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an integrated frequency converter.

Circulating Pumps
Circulating pumps move slurries, liquids, and gases through a closed system, keeping heating, cooling, and hot water circuits flowing as they should. They are most commonly used in domestic and commercial heating systems to maintain a steady supply of hot water, but they also play a key role in underfloor heating, radiator circuits, and chilled water applications.
By keeping water moving continuously, circulating pumps help balance temperatures, reduce energy waste, and ensure that taps, showers, and heating systems respond instantly when needed. Hot water circulating pumps are particularly useful in larger properties or commercial setups, where waiting for water to heat can lead to unnecessary water and energy use.
At Pumpify, our range includes circulating pumps suitable for everything from simple domestic setups to more complex commercial systems. Designed for easy installation, straightforward maintenance, and long-term performance, these pumps ensure your heating and hot water systems operate smoothly, reliably, and cost-effectively.
