Oase AquaOxy 2500 - Replacement Diaphram - Pack of 2 (74305)

This pack of 2 replacement diaphragms is designed for the Oase AquaOxy 2500 pond air pump. The diaphragms are key moving parts inside the air pump, helping to create the air pressure needed to push air through the airline and into the pond.

Over time, air pump diaphragms can wear, harden, stretch, or split. When this happens, the pump may still run, but its performance can drop noticeably, with reduced air output, weaker bubbles from the air stones, or an increase in operating noise.

Oase AquaOxy 2500 Replacement Diaphragm Set Features

• Pack of 2 replacement diaphragms for the Oase AquaOxy 2500 air pump
• Helps restore reduced air pump performance
• Useful if air output or pond bubble production has dropped
• Can help resolve increased pump noise caused by worn diaphragms
• Important service part for maintaining reliable pond aeration

The AquaOxy 2500 air pump supplies air to pond air stones or diffusers, producing bubbles that help improve water movement and oxygen transfer. If the bubbles in the pond have become weaker than normal, uneven, or have stopped from one outlet, worn diaphragms are one of the first service parts to check.

Replacing worn diaphragms can help the pump build air pressure correctly again, supporting steady airflow to the pond. This is particularly important during warm weather, overnight, or in ponds with fish, where reliable aeration helps support oxygen levels.

Good to Know

• Always switch off and isolate the air pump before carrying out maintenance
• Reduced airflow, weak bubbles, or louder running can indicate diaphragm wear
• Check airline, air stones, and filters as well, as blockages can also reduce air output

This genuine Oase replacement diaphragm set helps maintain the correct function of the AquaOxy 2500 pond air pump and is a useful spare part for routine pump servicing.
