Tunze 6055.700 replacement impeller for the Nanostream 6055 pump

The Tunze 6055.700 impeller is the genuine replacement part for the Nanostream 6055 circulation pump. After years of 24/7 saltwater operation, the impeller (also called drive wheel) can wear, calcify or bind — swapping it restores the pump's rated flow without replacing the whole unit.

Frequently asked questions

How often should the Nanostream 6055 impeller be replaced?

Wear-dependent: typically every 2-4 years in saltwater with regular maintenance (vinegar rinse every 6 months to remove calcification).

How do I know the impeller needs replacement?

Visibly reduced flow, unusual noise (grinding, vibration) or frequent binding — usually after cleaning no longer restores the calcification-free state.

Does this impeller fit Nanostream 6015, 6020, 6025 as well?

No — each model has its dedicated part. For the 6025 and 6045, see reference 6025.700.
