100,000 hours: KNF diaphragm pumps achieve astonishing longevity.

  • NEW
  • COMPANY

The exceptional durability of diaphragm pumps is not a coincidence. At KNF, this durability is thoroughly pursued in the design. 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.

The "Nautilus Fluidics" simulation application is now available for your use.

  • NEW
  • COMPANY

KNF's web-based software application "Nautilus" helps customers digitally simulate fluid systems and identify optimal gentle flow pump solutions. Nautilus is now available for testing by customers at KNF.com. By using this web-based fluid simulation application, users can recreate their systems digitally and compare the performance of various gentle flow pumps before integration. Fluid simulation software supports more efficient pump selection. With a simple drag-and-drop interface, customers can build simulations of their systems using components such as pumps, reservoirs, valves, and filters. By adding values relevant to their application, they can replicate actual operating conditions and assist in more accurate pump selection. "Nautilus" is compatible with KNF's gentle flow pumps. Nautilus can shorten the pump selection process through early and easy digital testing, reducing the need for physical testing and on-site support.
