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.

Biopsy devices require a reliable vacuum to obtain accurate results and must be low-noise for patient comfort.

Stable, reliable, and accurate flow in liquid diaphragm pumps When stable flow is important, KNF's Flow Control technology makes the operation of liquid pumps easy and reliable. The built-in sensors enable closed-loop control, allowing the diaphragm pump to automatically adjust motor speed to match the set values even under changing conditions. This includes external factors such as back pressure and fluid temperature changes, as well as internal factors like pump performance degradation at the end of the service cycle. The integrated flow sensor is optimized for the pump and directly transmits all data to the built-in pump control unit, achieving high setting accuracy. This makes it particularly suitable for applications where high precision is essential for measurement and dosing. This sensor employs ultrasonic flow meter technology to avoid contact with the fluid. This results in excellent leak prevention performance, enabling the transfer of almost any liquid, including corrosive, aggressive, and sensitive fluids.
