High-resolution drop-on-demand printing relies on perfect droplet formation. A diaphragm vacuum pump equipped with a vacuum controller stabilizes the meniscus inside the print head, ensuring accurate and reliable performance. Drop-on-demand (DOD) inkjet printing requires extremely high precision. Every ink droplet must adhere accurately to its designated position. A crucial element in this process is the curved ink surface, known as the meniscus, that forms at the tip of each nozzle. Stabilizing the meniscus is essential not only for print quality but also for maintaining the reliability and consistent performance of the system. The NVC 830 diaphragm vacuum pump with KNF's vacuum controller simplifies the system in demanding industrial printing environments.

Nadine Kuntz, the Product Engineering Team Leader, talks about her work, cross-departmental collaboration, and the role of product engineering at KNF. Since joining KNF Flodos AG in 2016, Nadine Kuntz has built her career from product engineer to product engineering team leader. Her interest in diaphragm pump technology began even earlier, sparked by a practical internship in the testing department. Currently, she is active at the intersection of technology, products, and people. In this interview, she discusses the realities of product engineering at KNF, the importance of collaboration, and the driving forces that support products and empower people.

Ensuring Safety and Hygiene with Food-Grade Diaphragm Pumps In the food and beverage industry, maintaining high hygiene and efficiency standards is extremely important. KNF's food-grade diaphragm pumps are designed to meet these needs, providing a reliable and safe solution for the transfer of gases, liquids, and mixed media. Made from materials compliant with food safety regulations, these pumps maintain product purity and ensure that it is safe for consumption. *The original blog is available in English only.*

The exceptional durability of diaphragm pumps is not a coincidence. At KNF, it is thoroughly pursued and designed. With pumps that operate for over 11 years under specified test conditions, OEM manufacturers can enjoy the benefits of reduced failures, cost savings, and improved reliability in critical applications. Ten years is not enough—KNF demonstrates what long-term reliability means. The NMP 850.1.2, proven to withstand 100,000 hours of operation under specified operating conditions, has set a new standard for the lifespan of diaphragm pumps. This groundbreaking achievement is the result of outstanding engineering rooted in product development focused on reliability. A rigorous testing policy ensures that all products meet the highest standards. As a result, pumps have been realized that enable OEM manufacturers to build safer, more efficient, and more durable systems.

Selecting the appropriate material for a diaphragm pump is key to achieving reliable, long-lasting, and contamination-free pump operation. This article explains the points to consider when selecting materials and introduces the most important and commonly used materials. Designing the optimal diaphragm pump for your application is like assembling a jigsaw puzzle. Only when all the pieces fit perfectly does the optimal solution come together. Among these, the selection of materials is an extremely important factor that affects the pump's lifespan, safety, and performance. So, what points should be considered when selecting materials for diaphragm pumps? And what are the reasons for these considerations?
