## Long description

Shaftless magnetic impeller designed for Fluval U4 aquarium filter (model FV-3335). This replacement impeller restores the pump's magnetic coupling and enables consistent water circulation and filtration performance in both freshwater and saltwater aquariums. The component is intended for maintenance and repair of Fluval U4 units to recover flow rate, reduce abnormal vibration and noise, and maintain overall filter reliability.
Advantages
The shaftless magnetic design eliminates the need for a metal shaft, reducing wear and points of failure while providing smoother, quieter operation. Made to match the geometry and magnetic alignment of Fluval U4 pumps, the impeller helps recover original flow characteristics and reduces vibration that can occur with worn or damaged parts. Installation of a correct replacement part supports efficient filtration and can extend the service life of the filter unit.

How to use
Turn off and disconnect the filter from power before servicing.
