News about this product(2)

Reasons why safety diaphragm pumps guarantee leak prevention in harsh environments.

  • Product news

By equipping a safety diaphragm, we ensure leak-free and contamination-free pump operation that meets the highest safety standards, even in the unlikely event that the working diaphragm is damaged. The very harsh environments in chemical and pharmaceutical processes, as well as the transfer of hazardous materials, toxic substances, and expensive fluids, impose high safety standards on the systems used. Safety diaphragm pumps achieve excellent leak prevention and airtightness by adopting an additional diaphragm as an extra layer of safety.

Challenging the limits of KNF pump low-temperature technology.

  • Product news

In the quest to push the limits of cryotechnology, cryostats are considered one of the most notable technological innovations. These complex devices are essential to scientific research, industrial processes, and space exploration due to their unparalleled ability to achieve and maintain temperatures close to absolute zero (the lowest possible temperatures). Essential components of diaphragm pump cryostat systems KNF's diaphragm pumps provide a versatile and customized approach to meet the unique needs of any application, whether in laboratories, industries, or other applications where reliable and efficient pumping solutions are required.
