Impeller for sera PS 200 aquarium pump model SE-45001 – replacement rotor/wear part

Replacement impeller compatible with the sera PS 200 aquarium pump model SE-45001. This rotor is designed as a wear part to restore the original hydraulic performance of the pump and maintain consistent water circulation in aquarium and filtration systems. The impeller helps reduce operational noise when worn components are replaced and supports efficient flow in both freshwater and marine tanks.

Advantages

The impeller is manufactured to match the form and function of the original part, allowing quick replacement without modifying the pump housing. By renewing the rotor and its magnetic assembly, users can recover rated flow rates and pressure characteristics while minimizing vibration and noise. The component uses standard materials suitable for continuous submersion and contact with aquarium water.

Suitable for

• Routine maintenance and scheduled replacement of worn impellers in sera PS 200 pumps
• Repair of pumps producing reduced flow or increased noise
• Use in freshwater and marine aquarium circulation and filtration systems

Key specifications

• Function: replacement rotor / impeller for aquarium pump
• Compatibility: designed for use with sera PS 200 pump model
• Material properties: corrosion-resistant materials suitable for aquarium water contact
• Operating environment: continuous submersion in freshwater or saltwater
• Purpose: restores hydraulic performance and reduces mechanical noise

How to use

Turn off and disconnect the pump from the power supply before servicing. Remove the pump cover or housing according to the pump manufacturer's instructions, extract the old impeller from the rotor chamber, and inspect the magnet and sleeve for wear or debris. Clean the rotor chamber and seating areas with fresh water, then install the replacement impeller in the correct orientation, ensuring the magnet assembly seats properly. Reassemble the pump, prime if required, and restore power to verify smooth operation and expected flow.

Usage recommendations

Inspect the impeller and rotor sleeve during regular maintenance intervals (for example, every 6–12 months depending on running hours and water conditions). Replace the impeller if there are signs of wear, excessive play, chips, or if flow and noise levels have degraded. Rinse the replacement part with aquarium water before installation and avoid lubricants or solvents that are not aquarium-safe.
