Why AODD Pump Diaphragms Fail: A Guide to Mechanical Stress & Strain Damage
If you operate Air-Operated Double Diaphragm (AODD) pumps, you already know that the diaphragm is the heart of the pump. It is the component that does all the work — flexing thousands of times per hour, pushing fluid through your system, and taking the full brunt of every pressure cycle. When it fails, everything stops. […]
Pumping Sulphuric Acid 98% with an AODD Pump: Challenges and How to Avoid Frequent Diaphragm Failure
Sulphuric acid at 98% concentration is one of the most demanding fluids you will ever ask an AODD pump to handle. It is not just corrosive — it is dense, with a specific gravity of 1.84, nearly double that of water. It generates heat on contact with moisture. And it will destroy the wrong pump […]
