Impeller cover Fluval CP1/CP2 A20338 – replacement part for Fluval pumps (MPN FV-3385)

Replacement impeller cover designed for Fluval CP1 and CP2 series internal pumps. This impeller cover fits directly onto the pump housing to protect the rotor and impeller while maintaining correct alignment and clearance. It helps restore intended flow and operational stability after wear or damage to the original cover, contributing to consistent circulation performance in aquarium systems.

Advantages

The impeller cover is manufactured to match the original shape and mounting points of Fluval CP1/CP2 pumps, ensuring a secure fit and simple installation. By protecting the rotor and impeller, the cover reduces the risk of contact with debris and minimizes vibration that can cause noise. Replacing a worn or cracked cover can also reduce the chance of leakage and help the pump maintain steady flow rates.

Suitable for

• Repairing or maintaining Fluval CP1 and CP2 series internal circulation pumps
• Restoring pump performance and reducing operational noise
• Routine aquarium pump servicing to ensure reliable water flow
• Replacement when original impeller cover is damaged, cracked, or lost

Key specifications

• Compatibility: Designed for Fluval CP1 and CP2 series internal pumps
• Function: Protective cover for rotor/impeller assembly
• Material characteristics: Durable molded component suitable for continuous aquatic use
• Mounting: Matches original pump housing attachment points for direct replacement
• Effect on performance: Helps restore correct impeller alignment, reduce vibration, and maintain flow stability

How to use

Turn off and disconnect the pump from power before beginning any maintenance. Remove the pump from the aquarium and drain water as needed to access the impeller chamber. Open the pump housing according to the pump model instructions, remove the old impeller cover, inspect the impeller and rotor for wear or debris, then place the replacement cover in the correct orientation and reassemble the housing. Reinstall the pump in the aquarium, refill if required, and run a brief test to ensure smooth operation and absence of leaks or unusual noise.

Usage recommendations

Inspect the impeller and rotor when replacing the cover; clean or replace worn components to achieve optimal performance. Use genuine-fit replacement parts and follow manufacturer service intervals to maintain reliable circulation and minimize risk of damage to the pump and aquarium environment.
