How to check if reference 59965502 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

- Compare the marked codes: 59965502, 0049FG, and MU1021400 (the latter is also marked on the pump and with the Fagor brand).
- Do not confuse it with other UPS 15-50 from Grundfos with different codes, such as the UPS 15-50 130 (59525600) or 96281418.
- Check on the PCB of your boiler that it is a Fagor FEE-20/2N or FE-20E/2B.

- Commercial statement from the seller of reference 59965502/MU1021400 (24/10/2026): Fagor FE-24, FE-24E, FE-24NOX, FEE-24, Superfagor, Contract and Eco-Compact. These are mentioned families, not verification of variants. Edesa/Aspes without specific models are not included as compatible.
Before purchasing
- To confirm: Fagor Ecocompact FE-20E/2N: and (MU1021400)
- To confirm: Fagor Superfagor, Contract and Eco-Compact (series), without specific models.
- To confirm: Fagor FE 24 E — and another pump (AS0015925); this is for the FE-24/FE-24E series. Contradictory: compare the code.
- Do not confuse: 59525600 — Grundfos UPS 15-50 130, with its own technical sheet in the official catalog — Another variant: it is not the 59965502.
- Do not confuse: 96281418 — Grundfos UPS15-50 (3 speeds, G 1", 130 mm) from the USA — Another article number; does not mention 59965502 or MU1021400.
- Do not confuse: AS0015925 — Pump that (ref. 280.34.0010) and (RS15/5-3) are for the Fagor FE 24 E — Another code for the FE 24 E in and in (this one is referred to as RS15/5-3). It has not been verified if it is the same pump.
- To confirm: The designation is written as "AC AO" (letter O) in, and "AC A0" (zero) in the title of that.
- To confirm: MU1021400 comes with UPS 15-50 AC AO; the 59965502, only. No official document read mentions its codes: the parts list from Fagor and the PDFs from Grundfos were blocked.
Frequently asked questions: Fagor 59965502
Where is the code for this pump and which one should I compare?
To confirm: On the pump itself, marked: Grundfos UPS 15-50 AC AO, with the codes 59965502, 0049FG, and MU1021400. MU1021400 is marked on the pump and with the Fagor brand: it appears next to UPS 15-50 AC AO in and .
Is it compatible with my Fagor FEE-20/2N or FE-20E/2B?
Yes. Confirmed: for the Fagor FEE-20/2N and for the FE-20E/2B. Additionally, the distributor provides the code MU1021400 for the FEE-20/2N.
Is it compatible with the Fagor Ecocompact FE-20E/2N?
We still don't have it confirmed for the FE-20E/2N. They provide the MU1021400 with the UPS 15-50 AC AO for that boiler. Confirmed: the FE-20E/2B: the suffix changes (2N versus 2B), so compare the PCB of your boiler or send us a photo from Contact.
What does each code mean: 59965502, 0049FG, and MU1021400?
UPS 15-50 AC AO is the Grundfos designation for the pump. 59965502 is its part number (marked on the pump and cited by ). MU1021400 is also marked on the pump: with the Fagor brand and referred to as Fagor's internal code. The 0049FG is marked on the pump, but we have not found any external confirmation that explains it.
Is another Grundfos UPS 15-50, like the 59525600, acceptable?
To confirm: Not without checking the code. The Grundfos catalog gives the UPS 15-50 130 its own technical sheet (59525600), and the UPS15-50 with the article 96281418. Neither mentions 59965502 nor MU1021400, so we do not consider them equivalent.
Is it compatible with the Fagor FE 24 E?
We do not have it confirmed and there are contradictions. For the FE 24 E, the pump AS0015925 (referred to as RS15/5-3) is given as UPS 15-50 AC A0 for the FE-24 and FEE-24 series. Compare the code before ordering it or send us a photo from Contact.
Who should install it and what information is marked on it?
We recommend that it be installed by a qualified technician. The unit is rated at 230 V ~ 50 Hz, with a capacitor of 2 µF, three steps (45, 70, and 100 W), and IP42.
