KNF Receives Award for Innovation Excellence

Diaphragm pump manufacturer fuels success story with tailor-made pump solutions

More than 280 invited representatives of AVL’s top technology suppliers from all over Europe attend the annual AVL Supplier Day. AVL is the world’s largest independent company for the development, simulation and testing of powertrain systems for passenger cars, commercial vehicles and large engines. At this year’s conference, high-ranking automotive industry experts discussed the future of the industry as well as new technologies. Topics included autonomous vehicles and electric drive mechanisms.

KNF received the AVL Supplier Award in the category of Innovation Excellence. CEO Günter Emig and Area Sales Manager Felix Ullrich proudly accepted the coveted prize from Prof. Helmut List, the CEO of AVL. Crucial factors in KNF’s favor were the flexibility and competence with which the company supplies custom-fit pump solutions.


Working off the series models of the heated N 024 gas sampling pump and the N 938 pump, KNF developed customized assembly solutions in close cooperation with AVL. The objectives were to integrate external system components in the sample gas pumps and to reduce their dimensions and the number of components, thus allowing them to be mounted more quickly and cost-effectively into the AVL system.


To achieve this, the stainless steel pump head was redesigned completely to enable the direct integration of certain components into the pump head, such as temperature and pressure sensor technology, AVL’s own valves and fittings, and sensing lines and heating elements. A customized attachment design guarantees optimal mounting of the pump assembly.


The motor control device was also adjusted to meet AVL’s needs. The motor software had to be adapted to the limited operating current, the defined motor startup characteristics, and individualized control parameters — the perfect opportunity for KNF to employ its skills as a motor developer and manufacturer, developing and implementing the necessary programming in-house.


KNF is extremely proud of winning the award for Innovation Excellence. This goes to show that, thanks to the KNF modular system, every series model pump can be converted into an individual pump solution — even for tasks as challenging as this one.
