The first 3D printers have been fitted with our diaphragm pumps. Our modular gas and liquid pumps were adapted to the specific needs of these machines in collaboration with the pioneers of jetting technologies. We are looking forward to even more exciting projects and the opportunity to use our extensive knowledge of pumps to continue to support this important cutting-edge technology.
We have been involved in jetting technologies for 3D printing from the beginning, and so we know that growth sometimes takes time. No matter the size of the production run you need, we produce and deliver an optimal solution.
In the end, it all comes down to an optimized print head with a seamless supply of binder. We have been producing pumps to perform this task for decades in industrial digital printing, where the medium is ink but the goal is the same – a perfectly functioning print head. Our diaphragm pumps ensure all of the functions required for continuous transfer of the binder, from transporting the binder to the print head to degassing, print head cleaning and purging to generating a vacuum for the meniscus effect.
Chemical resistance: In order to cope with binders of various chemical compositions whose aggressiveness can change with the temperature, KNF gas and liquid pumps offer scalable chemical resistance. When working with highly aggressive binders such as furan, for example, KNF liquid pumps are equipped with a PP pump head and a PTFE-coated diaphragm.
Satisfying process requirements: Our pumps are fully operational even at the low temperatures necessary for preventing the binder from hardening, and the elastomeric materials in the pump head and the diaphragm remain both completely functional and chemically resistant. As hazardous environments may occasionally occur, our liquid pumps are manufactured with protection class up to IP65, thus supporting the Ex requirements for the entire system. Equipping our diaphragm pumps with brushless motors promotes durability.
Maximum precision: KNF gas and liquid pumps fulfill a range of tasks within the 3D printer, always guaranteeing high-quality results. Our liquid pumps transfer the binder to the print head at the right time. Our gas pumps degas the binder, ensuring the functionality of the 3D print head and industrial-grade quality.
KNF offers a range of 70 series models designed for handling gases and liquids. The performances of these are described in our data sheets.
It is easy to tailor every series model to meet application-specific requirements by selecting and combining a variety of options. These range from the material used to make the pump components that come into contact with the media, to the drive and the mechanical elements such as the circuit points and connections. The configurations created by the KNF modular system are based on tried and tested individual components, meaning that developing customized pumps is quick and inexpensive.
Every application is different and some are one of a kind. Our modular system is designed to give you a high degree of flexibility, speed and reliability. You can be sure that every gas and liquid pump supplied by KNF will exactly meet your requirements, no matter how complex or unusual these might be. This includes a broad range of accessories. We work closely with you to design customized project pumps that give you a competitive edge in your target market. From its configuration to its testing conditions and packaging as well as customized warehouse and logistics concepts - your project pump is tailored to your particular needs.
