  1. Grundfos Magna1 D65-60F 99221377 Twin Variable Speed Circulator - 340mm - 230v

    99221377

    Grundfos - Magna1 D65-60F 99221377 Twin Variable Speed Circulator - 340mm - 230V - Cast Iron

    MAGNA1 D 65-60 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.

    Suitable for: Commercial heating, Commercial air conditioning, District heating, District cooling, Domestic heating, Industrial heating

Heating Circulators

Heating Circulators

Heating circulator pumps keep hot water moving through radiators, baseboards, and underfloor heating systems. They ensure your heating system delivers warmth quickly, reduces waiting times for hot water, and keeps energy use under control.

 

Whether used individually or in combination, circulator pumps can serve multiple zones, giving precise control over each area of your property. In multi-zone systems, one circulator can serve all areas using control valves for each section, or you can fit a dedicated pump to each zone for precise, independent flow.

 

Modern circulators save significant power while maintaining consistent flow. Pumpify offers a range of trusted models from big name brands that are built for durability, smooth operation, and long-lasting performance, helping you get the most out of your heating system.
