High Performance with Improved Protection
KNF double diaphragm pumps offer a high level of performance and greatly enhanced safety, especially when working with dangerous, rare and valuable gases.
A “safety diaphragm” is located underneath the working diaphragm, providing additional protection.
Being under less mechanical stress when the pump is operating, the safety diaphragm has a significantly longer service life. Thus ensuring that no gas can escape into the environment even if the working diaphragm ruptures.
