Smooth Flow

KNF FP 70 is a new addition to the Smooth Flow product lineup, providing the benefits of diaphragm pumps with a pulsation level comparable to gear and centrifugal pumps.

Strong Performance

Developed for an operation of up to 2 bar pressure, the FP 70 delivers a flow rate of up to 0.85 l/min. Thanks to the improvements in its structure, the pump can operate smoothly without supplementary pulsation dampening elements and tubings.

Various Customization Options

Another key advantage is the patented 4-point valves, which enable reliable self-priming. Additionally, numerous motor options and precious parameter customization possibilities make the FP 70 perfect for customers looking for an excellent low-pulsation pumping solution.
