Swell Maxi Air Pump Replacement Diaphragms

Each diaphragm is sold separately. If looking to order more than one diaphragm, you will need to update the quantity in your basket. 

Diaphragms are a moving part within the Pond Maxi Air Pump and over time will stretch and can split, reducing the output of the air pump. They are made from a silicone rubber for excellent reliability and life expectancy but will eventually need replacing.

Diaphragms are a moving part of the product and are not covered under warranty.
