Full Description

Pump overview

The Grundfos MAGNA1 25-60 is a high-efficiency variable-speed circulator pump from the Magna 1 family — Grundfos’s simple, reliable choice when straightforward, energy-efficient circulation is required without the advanced control of the Magna 3.

Within the Magna 1 range, the 25-60 is the most commonly specified model — a 6 m head suits a typical UK 3- or 4-bedroom heating system. The 25mm (G 1½”) port and standard 180 mm port-to-port length mean it drops into the spot of the older fixed-speed pump it’s replacing without re-piping.

A permanent-magnet motor with integrated frequency converter matches flow and head to system demand, cutting electricity use against older circulators by a substantial margin. EuP 2015 compliant with an Energy Efficiency Index of 0.20. Backed by a 2-year Grundfos manufacturer warranty.

Key features

Variable speed PM motor

Permanent-magnet motor with integrated frequency converter. Adjusts speed to match demand — constant pressure, far higher efficiency than older asynchronous circulators.

EEI 0.20 — EuP 2015 compliant

Energy Efficiency Index of 0.20 — well below the EuP 2015 threshold. Direct drop-in replacement for older inefficient fixed-speed pumps with substantial electricity savings.

180 mm drop-in fit

Standard 25mm (G 1½”) circulator footprint — fits the spot of most older domestic pumps without re-piping or modifying the system.

Maintenance-free canned rotor

No mechanical seal, no routine servicing. Carbon-fibre reinforced rotor can, stainless steel bearing plate and rotor cladding, aluminium stator housing.

Grundfos GO Remote app

Wireless connection to the Grundfos GO Remote app — pump setup, control and monitoring from a phone, no extra hardware required.

Fault relay & start/stop input

Built-in fault relay output for connection to a BMS or external alarm. Digital start/stop input allows remote on/off control from a panel.

Wide liquid temperature range

−10 °C to +110 °C. Suitable for heating, cooling, chilled-water and ground-source heat pump systems.

UKCA approved

Approvals: CE, VDE, EAC, UKCA, Morocco, TSE, RCM, UkrSEPRO. Environmental: CN ROHS, WEEE.

2-year Grundfos warranty

Standard Grundfos manufacturer warranty when purchased from Anglian Pumping, an authorised distributor.

Typical applications

Domestic heating — main pump

Primary circulator for UK heating systems. The 6.0 m head suits standard domestic pipework with the corresponding emitter load.

Mixing loops

Secondary circulation for mixing valves and blending loops in zoned or multi-circuit systems.

Heating surfaces — UFH

Underfloor heating manifolds and emitter circuits.

Ground-source heat pump systems

Primary or secondary loop circulator. The wide −10 °C to +110 °C range covers brine and water side.

Air-conditioning surfaces

Chilled-water circulation in fan-coil and surface-cooling systems.

Small chiller circuits

Light commercial chiller and process-cooling loops within the pump’s flow and head envelope.

Frequently asked questions

What does the model number 25-60 mean?

The Magna 1 naming convention reads as port size – maximum head in decimetres. So 25-60 = 25mm port with 6 m maximum head. The 25-60 has a standard 180 mm port-to-port length, shared across the entire 25mm Magna 1 range.

Will the MAGNA1 25-60 replace my existing pump?

In most UK systems, yes. The 180 mm port-to-port length matches the standard footprint for 25mm (G 1½”) circulators, so it fits the spot of the older fixed-speed pump it’s replacing without re-piping. What you need to check is the head requirement of your system. If the existing pump runs at maximum (constantly noisy, struggles to reach distant emitters), step up to the MAGNA1 25-80 (8 m head). If it ran comfortably below maximum, a smaller model in the 25mm range would use less energy. Contact us if you’d like help sizing.

Are pipe unions included?

No — the MAGNA1 25-60, like all Magna 1 pumps, ships without union connectors. Pair it with the 25mm Magna union set (1¼” BSP). We supply matching unions for all Magna 1 sizes.

Does it work with the Grundfos GO Remote app?

Yes. All current Magna 1 pumps include wireless connection to the Grundfos GO Remote app. Use the app for pump setup, mode selection, head and flow display, and monitoring from your phone — no extra hardware required.

What control modes does it support?

The Magna 1 supports proportional pressure and constant pressure control, plus three constant-curve speed settings. Mode is selected via the on-pump operating panel or the Grundfos GO Remote app. The pump arrives factory-set for proportional pressure, which suits most variable-flow heating systems.

What’s the warranty?

2 years manufacturer warranty direct from Grundfos when purchased from Anglian Pumping, an authorised Grundfos distributor.

Where is it manufactured?

Grundfos Magna 1 pumps are manufactured in Germany. Custom tariff number 84137030, country of origin DE.

Is it suitable for cooling and chilled-water systems?

Yes. The −10 °C to +110 °C liquid temperature range covers heating, cooling, chilled-water, ground-source heat pump primary loops, and small chiller applications. The pump housing is cast iron — for closed-circuit heating and cooling. For potable water or open-vent systems, a stainless steel Magna 1 N variant is required instead.

How quiet is it?

The Magna 1 uses a permanent-magnet motor with no mechanical seal, so it runs significantly quieter than older asynchronous circulators. There’s no published dB(A) figure on the datasheet — but in practice it’s quiet enough for installation in airing cupboards and utility rooms without nuisance.
