KNF designs and manufactures diaphragm pumps for sampling, transferring, evacuating and compressing process media for many industrial applications. Our oil-free diaphragm pumps meet discerning engineer's requirements for robust and contamination-free performance under the most challenging and corrosive conditions. Additionally, our modular system allows us to custom-design pumps to meet your specific application requirements.
ATEX pumps are designed to prevent internal or external explosions by enclosing parts that could ignite. KNF ATEX-compliant pumps are certified in accordance with the 94/9/EC directive on equipment and protective systems.
Equipment for Explosive Atmospheres (ATEX) - European Commission references standards on equipment and protective systems intended for use in potentially explosive atmospheres.
