When Chemical Compatibility Charts Are Not Enough: The Case for System-Level Chemical Validation
Chemical compatibility charts give you a starting point. They do not tell you whether your specific system will fail. The chart says EPDM is compatible with 30% sulphuric acid — and it may be, under the test conditions used to generate that data. Those conditions may not match your operating temperature, your concentration, your exposure […]
The Relationship Between Stroke Rate and Pulsation — And Why It Matters Downstream
Every stroke of an AODD pump delivers a discrete pulse of fluid. This is not a defect — it is the fundamental operating principle of any positive displacement pump. But pulsation is also one of the most overlooked sources of process problems downstream, and the stroke rate you set has a direct and predictable effect […]
