The performance of a diaphragm pump is greatly influenced by the configuration of the pump head. Let's learn how various configurations affect flow rate, vacuum level, and overall performance, as well as how to choose the optimal configuration for your application. The optimal pump head configuration is determined by the required flow rate and vacuum level. Choosing the right solution is extremely important as it directly impacts the performance of the application. Engineers can choose from single-head, dual-head, or multi-head designs, and these can be connected in parallel, in series, or in combination.

Berlin Heart uses KNF diaphragm pumps, characterized by their sustained accuracy and quiet operation, in their ventricular assist devices. Our hearts are a miracle created by nature. The heart beats tirelessly up to 100,000 times a day. This is a given for healthy individuals. However, the situation is different for patients with heart disease who urgently need a new heart. Their chances of survival depend on whether a compatible heart transplant donor can be found. Unfortunately, this often requires a long wait. During this waiting period for a transplant, ventricular assist devices (VADs) can help support the patients.

The six astronauts on the International Space Station (ISS) travel through space at a speed of 28,000 kilometers per hour, orbiting the Earth 16 times a day. The crew's survival is ensured by the design of the "living and working space" that can withstand extreme environments. The ISS provides the necessary stability, and its shell and glass protect the interior from heat, cold, and pressure loss. Additionally, efforts have been made to create an environment in space that is as close as possible to that on Earth. The survival of the astronauts depends on the reliability of all systems and components. The pumps used in space were completed in the fall of 2018. Ultimately, two pumps were incorporated into the new life support rack.

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.

Composting facilities emit large amounts of greenhouse gases, causing specific environmental issues. However, by capturing these gases, it is possible to mitigate their impact on the environment and convert them into useful resources. New methods to enhance environmental sustainability are becoming increasingly common. One of the main focuses in the ongoing efforts toward sustainability is the emission of greenhouse gases, which has become a significant concern across various sectors. The agricultural sector is often cited as a major source of greenhouse gas emissions. One of the primary sources of these emissions is the composting facilities that are essential for livestock farming. However, recent initiatives are underway to convert these emissions into high-quality biogas. Diaphragm pumps are essential for the transfer of gases in this process.
