KNF double diaphragm pumps offer a high level of performance and greatly enhance safety, especially when working with dangerous, rare and valuable gases. A second diaphragm is located underneath the working diaphragm. The safety diaphragm has a significantly longer service life than the working diaphragm, thus ensuring that no gas can escape into the environment even if the working diaphragm ruptures.
