This is a replacement diaphragm for the Stellar S-30 aquarium air pump. The rubber diaphragm is the part that pushes air through your pump. Over time, constant vibration can wear it thin or cause small tears, which reduces airflow or stops the pump working.

Replacing a worn diaphragm can restore your pump’s airflow, which is often far cheaper than buying a new pump.

Key Features

• Restores airflow: Replaces a worn or torn diaphragm to bring back steady bubbles.
• Extends pump life: Keeps a working pump motor in use instead of replacing the whole unit.
• Model-specific: Made to fit the Stellar S-30 air pump.

How to Use

1. Switch off and unplug the air pump.
2. Open the pump housing, usually via screws on the base.
3. Remove the worn diaphragm, noting how it’s fitted.
4. Fit the new diaphragm in the same position, reassemble the pump and switch it back on.

Please note: Check your pump’s model number before ordering, as diaphragms are model-specific. Always unplug the pump before opening it.

Suitable For: Owners of the Stellar S-30 aquarium air pump who need to restore airflow from a worn pump.
