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 for the label on your pump motor: it should indicate Wilo, model RSB15/5-1 Ku P, and code 4513443.
- Compare the data on the label: ~230 V · 50 Hz, 88 W, 0.38 A, 2200 min⁻¹, PN6, IP44, class F · TF95 and capacitor of 2.6 µF · 400 VDB.
- Don't rely solely on the name. The codes 4511638 and 4512476 are other Wilo pumps. Always compare the complete code.
- Check the connections of your pump: G 1" thread and Ø30 x Ø21 x 2.1 (EPDM) gasket. Also measure the distance between the ports and see where the connection box is located.
- If everything matches, call us at 911 17 77 77 with your boiler model to confirm compatibility before purchasing. You can also send us a photo of your pump label and the boiler's specification plate from the Contact section.

Frequently asked questions about the circulation pump
How do I identify the Wilo RSB15/5-1 Ku P 4513443?
Check the motor label: it should indicate Wilo, model RSB15/5-1 Ku P, and code 4513443. This pump also marks ~230 V · 50 Hz, 88 W, 0.38 A, 2200 min⁻¹, PN6, IP44, class F · TF95, capacitor of 2.6 µF · 400 VDB, and "Made in EU." The 88 W is the power and the 0.38 A is the current. The model can also be written as RSB 15/5-1 Ku P, RSB15/5-1KuP, or RSB15-5-1 Ku P; the code remains the same.
What boiler is the Wilo 4513443 compatible with?
