CONFIGURED TO MEET DOD AND CIJ REqUIREMENTS
From ink supply and degassing to the cleaning and purging of print heads, vacuum generation on the print heads for the meniscus effect and ink circulation, our customized, comprehensive solutions use gas and liquid pumps to perform all the processes needed to ensure the continuous transfer of ink. kNF’s diaphragm pumps are tailored to all the specific requirements of both DOD and CIJ technology.
Fully adaptablekNF pumps are known for their outstanding flexibility. With their compact design, ability to be installed in any position and fully adjustable controls, all pump compo-nents can be adapted to meet the exact needs of your equipment.
Chemically resistant and robustWhen designing our gas and liquid pumps, we take the chemical composition of the ink, the pigment density and the use of solvents into account. To ensure that our solution fulfils your specifications, you can choose to have your wetted pump components produced from
like FFkM, PTFE, EPDM, FkM and others. kNF pumps are able to transfer all types of ink used in the printing industry, from water-based and pigment inks to solvent-based and UV inks. What’s more, even our pump name plates are solvent resistant.
Flexible and efficient levels of performanceThe wide array of industrial inkjet printing solutions on the market cover an extensive range of sophisticated printing processes. The variety of options available in our modular system help you to stand out from the crowd and can be used to create a solution with a price/performance ratio tailored precisely to any set of requirements.
