Oase AquaOxy 7500 - Replacement Diaphram - Pack of 2 (74313)

This pack of 2 replacement diaphragms is designed for the Oase AquaOxy 7500 pond air pump. As internal working parts, the diaphragms help the pump create the pressure needed to deliver air through the airline and into the pond.

With regular use, diaphragms can wear or become less effective. This can lead to lower air output, reduced bubble production from pond air stones or diffusers, uneven aeration, or a noticeable increase in pump noise.

Oase AquaOxy 7500 Replacement Diaphragm Set Features

• Pack of 2 replacement diaphragms for the Oase AquaOxy 7500 air pump
• Helps restore lost air pressure and reduced pump output
• Useful where pond bubbles have become weaker or less consistent
• Can help address increased noise caused by worn internal diaphragms
• Genuine Oase service part for maintaining air pump performance

The AquaOxy 7500 is used to provide pond aeration through connected air stones or diffusers. Good bubble production helps move water and support oxygen transfer, which is especially important in warmer weather, at night, or in ponds with a higher fish load.

If the pump is still running but the air delivery has reduced, replacing the diaphragms can be an effective maintenance step. It is also worth checking the air filter, airline, and air stones at the same time, as restrictions in the system can also reduce aeration.

Good to Know

• Always isolate the air pump from the mains before carrying out maintenance
• Reduced airflow, weak bubbles, uneven output, or louder operation can indicate diaphragm wear
• Replace diaphragms as a pair where supplied as a set, to help maintain balanced pump operation

This genuine Oase replacement diaphragm set helps support the correct operation of the AquaOxy 7500 pond air pump and is a useful spare part for restoring reduced aeration performance.
