How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look at the motor plate: it should say NYE43-15 P Ku and the code 4512946.
- Also compare reference 4512937 and the data from the PCB: 230 V, 88 W, and capacitor of 2.6 µF.
- Do not confuse it with the NYL 43-15 (195000050) or the DYA43-15 P (122075100): they are different models with different codes.
- Measure your pump: a similar model (Salmson NYE 43-15-Ku P) has 1" and 130 mm, without confirming that it is the same part.
- If they match, call us at 911 17 77 77 with your boiler model and we will confirm availability.
