Genuine Oase Replacement Rotor & Impeller Assemblies
Model-specific rotors for ASE/Filtral 2500 and older Aquarius 900 pumps
A worn, swollen or damaged rotor can leave an otherwise serviceable pump noisy, reluctant to start or low on flow. These are genuine Oase assemblies, but they belong to different pump families and are not interchangeable.

Diagnose before replacing
- Disconnect the electricity before removing the pump.
- Clear the cage, impeller chamber and hose restriction first.
- Inspect the ceramic shaft, magnet, blades, bearings and O-rings.
- Replace cracked or swollen components; do not sand the magnet to make it fit.
- Refill and bleed a dry-installed pump before restarting.
A rotor will not repair a failed stator, damaged cable or cracked motor block. If the electrical body is suspect, replace the complete pump. Browse our pond pumps and genuine service parts.
