Compact yet robust, the German-engineered KNF N86 N89 series diaphragm gas pumps—like the KTE variant—thrive in R&D labs, gas analytics, bioprocessing, environmental monitoring, and industrial online analysis systems, running continuously 24/7 .
We equipped the KTE version with a corrosion-resistant PTFE diaphragm to boost longevity and handle vapor or condensation with ease.
The purpose of the design of KNF diaphragm gas pumps is to transfer, compress, and generate a vacuum for gases and vapors, without contaminating the media.
You can customize them to your exact needs, with options for motor type (AC, DC, brushless), control interface, voltage, and materials that resist chemicals, vibration, noise, and extreme temperatures .
Every N 86-series pump delivers oil-free operation for clean, maintenance-free performance.
