Technical overview
About these figures
These figures provide simplified information for searching, filtering and initial comparison. They are not a complete specification. Exact details depend on the model and configuration.
Power rating: Usually the motor’s rated mechanical output (P2). Electrical input power (P1) is a different value. Check the product’s nameplate or manufacturer’s documentation to confirm which rating applies.
Outlet size: The nominal size class is expressed on a millimetre basis: for example, DN40 denotes a nominal 40 mm size. It does not specify the exact measured opening, connection type, thread, flange drilling or pressure rating.
Head and flow: Indicative figures describing the pump’s performance envelope, rather than a single operating duty point. Do not assume maximum flow is available at maximum head, or that every combination within the ranges is achievable. Minimum figures do not establish safe continuous operating limits. Consult the relevant performance curve.
Check the product description, nameplate and manufacturer’s documentation before selection or installation. Please contact us before purchasing if you need help confirming suitability or connection details.

GRUNDFOS MAGNA1 32-60 180 – Circulator Pump 99221234 (2022) #4423 (USED)
This listing is for a Grundfos MAGNA1 high-efficiency wet-rotor circulator pump. MAGNA1 is designed as a simple, reliable and maintenance-free solution for heating and cooling circulation where basic control and monitoring are required without the complexity of advanced building management integration.
The pump features a permanent-magnet synchronous motor with integrated frequency converter, providing significantly higher efficiency than traditional fixed-speed circulators and ensuring compliance with EuP energy regulations.
Condition: supplied as a used pump. The unit shows cosmetic wear consistent with previous service use.
It is inspected prior to dispatch and confirmed operational.
Guarantee: supplied with our 6-month guarantee.
- Pump type: MAGNA1 wet-rotor electronically controlled circulator
- Connection: G 2" union (PN10)
- Port-to-port length: 180 mm
- Electrical supply: 1 × 230 V, 50 / 60 Hz
- Motor: 4-pole permanent-magnet synchronous (PM)
- Control: integrated frequency converter with user interface
- Communication: Grundfos GO Remote compatible

Frequently Asked Questions
Why choose a MAGNA1 instead of a MAGNA3?
The MAGNA1 is intended for users who need a high-efficiency, reliable circulator without advanced BMS features. Compared with MAGNA3:
- MAGNA1 offers simpler setup and operation with lower cost
- Ideal where only basic control modes are required
- Still provides major energy savings via PM motor and integrated drive
- Includes fault relay and digital start/stop input
Choose MAGNA3 when you need:
- Advanced flow estimation and heat-energy monitoring
- Full building management communication (BACnet/LON)
- Multi-pump cascade and advanced control functions
For straightforward HVAC circulation where simplicity and efficiency are the priority, MAGNA1 is usually the better value choice.
Is the pump maintenance-free?
Yes. MAGNA1 uses a canned-rotor wet-rotor design with no mechanical seal, eliminating routine seal replacement and providing very quiet operation.
Can this replace older fixed-speed pumps?
Yes — subject to hydraulic match. The variable-speed electronics in a MAGNA1 can provide major energy savings compared with a fixed-speed pump, but system duty and connection type should be confirmed before replacement.
Are union tails included?
This model uses G 2" union connections. Union tails or mating fittings are not included unless specifically shown in the product photographs.
