Product information

Description

The sera Impeller with Shaft and Cap for 400 + UV Aquarium Filter is a genuine replacement assembly designed specifically to maintain the performance of sera 400 + UV aquarium internal filters. Over time, mechanical components in aquarium pumps experience wear from continuous operation, which can lead to reduced water flow and increased noise levels. This replacement set restores the original operating efficiency and quietness of your filtration system.

Advantages

Using authentic replacement parts ensures a precise fit and reliable operation within your existing setup. This impeller assembly restores optimal water circulation and filtration performance, helping to maintain a healthy aquatic environment. Regular replacement of worn parts prevents sudden pump failures and extends the operational lifespan of your aquarium filter.

Suitable for

  • Replacing worn or damaged impellers in sera 400 + UV internal filters
  • Routine maintenance and servicing of aquarium filtration equipment
  • Restoring original water flow and reducing pump noise

When it may not be suitable

This component is exclusively designed for specific filter models and will not fit internal filters from other manufacturers or different sera filter series. It is also not suitable if the underlying issue with the filter is related to electrical faults or damaged power cords rather than mechanical wear of the impeller.

Key specifications

  • Compatible with sera 400 + UV aquarium internal filters
  • Includes impeller, shaft, and cap
  • Designed for internal pump assembly

How to use

Before performing any maintenance, always disconnect the aquarium filter and all other submerged electrical equipment from the power supply. Open the filter housing according to the manufacturer instructions and carefully remove the old impeller assembly from the motor block. Insert the new sera impeller with shaft and cap into place, ensuring it rotates freely without obstruction. Reassemble the filter housing, install the unit back into the aquarium, and reconnect the power supply.

What to consider before purchase

  • Verify your specific aquarium filter model to ensure compatibility with the sera 400 + UV parts
  • Inspect the current impeller and housing to confirm that the mechanical parts are the source of the issue
Usage recommendations: Inspect the impeller assembly periodically during routine aquarium maintenance to check for debris buildup, calcium deposits, or physical wear, and clean gently with water if necessary.
