In the semiconductor and chemical industries, the fluid transportation link is regarded as the "lifeline" of production operations, and PTFE diaphragm pumps are the core and most reliable key equipment on this lifeline. Whether it is the precise transportation of ultra-high-purity fluids in semiconductor chip manufacturing or the safe transfer of corrosive media in chemical production, every link from product R&D and manufacturing to rigorous pre-delivery testing is handled with extreme care. The goal is to ensure the stability and safety of the products and provide protection for industrial production.
Different from ordinary transportation equipment, PTFE diaphragm pumps can perfectly adapt to the special needs of the two industries relying on their unique material advantages and structural design—resistance to strong acids and alkalis, no medium pollution, and precise transportation. This is the key reason why they can become the core dependency. This "reliability" is never an empty slogan; instead, every pump must pass four extremely strict, even harsh, key tests before leaving the factory for use.
The first is the flow stability test. Links such as semiconductor lithography and chemical proportioning have extremely high requirements for the accuracy of fluid flow, and even a slight fluctuation may affect product quality. Therefore, each pump undergoes repeated debugging and testing to ensure that the flow fluctuation is strictly controlled within ±5%. Even during long-term continuous operation, it can maintain stable output, eliminating potential production hazards caused by flow deviations.
The second is the sealability test, which is the bottom line for ensuring production safety. We conduct a continuous leakage test on each pump for up to 72 hours, strictly controlling the leakage rate to no more than 0.1 milliliters per 24 hours. It should be noted that even a tiny leakage of corrosive media in the chemical industry or high-purity reagents in the semiconductor industry will not only cause material waste but also may lead to safety accidents or product scrapping. Therefore, this test must achieve zero tolerance.
The third is the corrosion resistance test, which also verifies the core advantage of PTFE material. We soak the key components of the pump body in highly corrosive solutions such as HF (hydrofluoric acid) and HNO₃ (nitric acid) to simulate actual industrial application scenarios. After soaking for a specified period of time, we use HPLC (high-performance liquid chromatography) analysis technology to accurately detect whether the components are corroded or whether the material is precipitated. This ensures that when in long-term contact with corrosive media, the pump can still maintain structural integrity and stable performance without polluting the transported medium.
The last one is the extreme condition test, which tests the pump's ultimate adaptability. The industrial production environment is complex and changeable, and temperature and pressure are inevitably subject to fluctuations. Therefore, each pump is subjected to continuous testing at a high temperature of 100℃ while bearing a maximum pressure of 150psi, verifying that it can still operate normally without faults or leaks under extreme working conditions.
It is these rigorous tests and every meticulous manufacturing detail that enable PTFE diaphragm pumps to firmly establish themselves in the semiconductor and chemical industries and become the "ballast stone" for the fluid transportation link. From R&D to factory delivery, and from testing to application, every step of perseverance is to provide more stable, safer and more reliable transportation guarantees for industrial production, helping the two industries achieve high-quality development.
