## Long description

Replacement impeller cartridge Fluval A20174 for 304/404 filters is a direct-fit rotor assembly designed to restore the original pump performance of compatible Fluval canister filters. The cartridge contains the impeller and its housing components required to maintain efficient water circulation and filtration in freshwater and marine aquariums. It is intended for routine maintenance or when existing moving parts show signs of wear, noise, reduced flow, or vibration.
Advantages
This impeller cartridge restores proper flow rate and helps reduce operational noise and vibration by replacing worn or damaged rotor components. The unit is engineered to match the original dimensions and tolerances of the filter’s pump chamber, ensuring reliable alignment and smooth rotation. Replacing the impeller can extend the life of the pump motor by reducing strain from imbalanced or worn parts and contributes to stable filtration performance.
Suitable for
Routine maintenance of Fluval 304 and Fluval 404 canister filters
Repairing reduced water flow or increased vibration in the pump
Restoring quiet operation after impeller wear or damage
Use in freshwater and marine aquarium filtration setups
Key specifications
Component type: complete impeller/rotor assembly with housing parts
Compatibility: specifically for Fluval 304 and Fluval 404 canister filters
Function: restores impeller rotation, maintains water circulation and pump balance

How to use
Turn off and unplug the filter and disconnect hoses from the unit before opening the canister. Remove the old impeller cartridge from the pump chamber according to the filter manufacturer’s service instructions, then inspect the pump housing and shaft for debris or buildup. Install the replacement impeller cartridge in the same orientation as the original, ensuring it seats fully and rotates freely by hand before reassembling the filter. Reconnect hoses, refill the canister as required, plug in the unit and monitor the flow to confirm proper operation.
Usage recommendations
Inspect and clean the impeller chamber and intake screens regularly to prevent premature wear. Replace the impeller cartridge immediately if you observe persistent noise, reduced flow, or visible damage. Use genuine or compatible replacement parts designed for Fluval 304/404 models to maintain performance and protect the filter motor.
