KNF FP7 Series FP25 Pulsation Mitigation Diaphragm Liquid Pump

From high-resolution inkjet printers to life-saving devices, KNF's advanced flow technology delivers smooth, turbulence-free performance in situations where precision is everything. Gentle Flow Pump – A groundbreaking product in diaphragm pump innovation KNF's Gentle Flow series employs two advanced design techniques to achieve minimal pulsation. One is a design that uses an internal damper integrated within the pump to absorb pressure fluctuations. The other is a design that connects up to five diaphragms in parallel, operating each with a phase difference to smooth the flow. Both configurations minimize vibration and noise, enabling precise flow control through a built-in brushless DC motor.

With the development of the Gentle Flow Pump, KNF has minimized the pulsation of liquid diaphragm pump systems and set a new standard for diaphragm pump technology. In this interview, Daniel Kohli, the head of product development at KNF Flodos, the liquid pump product center, provides unique insights into the development process, technology, and key benefits for customers. He also discusses KNF's first pump equipped with intelligent features, which is the latest innovation project.

The new KNF FP 1.70 combines many advantages of diaphragm pump technology with the benefit of a smooth flow with almost no pulsation. Launched as the high discharge pressure version of the FP 70, the FP 1.70 allows for a maximum pressure of 6 bar (relative), providing cutting-edge diaphragm pump technology that is ideal for the most demanding industries.

In the pursuit of sustainable energy solutions, diaphragm pumps provide precise control, safety, and efficiency as a crucial component in hydrogen management within fuel cell systems. As the world moves towards decarbonization, hydrogen fuel cells have emerged as a potential foundational technology for more sustainable energy generation. Within such systems, diaphragm pumps perform several key functions that directly impact performance and lifespan, from hydrogen recirculation to condensate management.
