Jetting-Technologie im Fokus

Jetting technology
in the spotlight

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.

KNF modular system

How we collaborate to optimize your pump

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.

Series models – the first step to customized pumps

KNF offers a range of 70 series models designed for handling gases and liquids. The performances of these are described in our data sheets.

The KNF modular system for creating customized pumps

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 to tried and tested individual components, meaning that developing customized pumps is quick and inexpensive.

Project pumps – precisely designed for the application

We support your development project by providing you with sample pumps quickly and easily. In consultation with you, our employees from the sales, engineering, and product management divisions determine the modifications to be made to the product’s standard technical parameters.
