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.
- Locate the round label on the pump. It features the Vaillant logo, "Type VPAL-7/2A" and "P/N 59866551". The Grundfos logo is also on the same label.
- Read the complete P/N, digit by digit: it must be 59866551. Do not stop with just the first digits.
- Compare the label data: 230 V~, 50 Hz, 2.5 μF, IP44, the markings "Class H" and "TF 95," and the two rows 0.39 A · 85 W and 0.44 A · 100 W.
- Check the complete model on your boiler's label, including the revision (for example VU 376/3-5 R1), and verify that it is an ecoTEC plus 637, 837, or 937 from the compatibility list.
- Compare the electrical connector and the water connections of your current pump with the photos.
- If your pump has a different code (0020025043, 8000011227) or you have questions about your boiler model, call us at 911 17 77 77.
