Impeller Shaft for PS 200 aquarium pump, sera SE-45002 replacement part

Replacement impeller shaft designed specifically for the sera PS 200 aquarium pump. This precision-made rotor pin restores correct rotor alignment and supports the impeller to re-establish proper water flow through the PS 200 unit. It is intended as a spare part for maintenance or repair when the original shaft shows wear, bending, or damage that affects pump performance.

Advantages

The replacement impeller shaft is manufactured to match the form and fit required by the PS 200 pump, allowing quick restoration of impeller rotation and reduced vibration. Using a correctly sized shaft maintains the pump's designed axial alignment, which helps preserve seal life and reduces noise. The part is compact and easy to handle during routine service or part replacement.

Suitable for

• Repairing sera PS 200 aquarium pumps with worn or bent rotor pins
• Routine maintenance to replace an aging impeller shaft
• Restoring proper circulation in freshwater or marine aquarium systems driven by PS 200

Key specifications

• Function: impeller shaft / rotor pin for PS 200 pump
• Compatibility: designed for installation in PS 200 aquarium pump models
• Material: corrosion-resistant metal suitable for continuous water contact
• Form factor: precision cylindrical shaft sized to match original PS 200 rotor geometry

How to use

Power off and disconnect the PS 200 pump from the aquarium before attempting replacement. Remove the pump housing and extract the existing impeller according to the pump's service instructions. Withdraw the damaged shaft from the rotor assembly and install the replacement shaft, ensuring correct seating and alignment of the impeller. Reassemble the pump housing, verify free rotation of the impeller by hand, then reinstall the pump and reconnect power. Observe initial operation to confirm stable flow and absence of unusual noise or vibration.

Usage recommendations

Inspect the impeller and shaft periodically as part of routine maintenance; replace the shaft promptly if you notice wobble, scoring, or corrosion to maintain pump efficiency and prevent further damage to bearings or seals.
