Low Pulsation, Less Than 150 mbar
Combining the advantages of diaphragm pump technology with a pulsation level comparable to gear pumps, the FP 400 is an innovation from KNF, targeting recirculation applications in a diverse set of markets.
Pulsation for FP 400 is less than 150 mbar. Levels far below this are achievable, depending on the configuration. The pump delivers up to 5 l/min of liquid at back pressures to 1 bar g, with full linear control of flow between 10% and 100% of the nominal flow rate.
Low Shear, Low Vibration and More
The pump flow is completely stable with fluid viscosities ranging from 1 to 150 cSt. With some flow rate reduction, the FP 400 can handle viscosities up to 500 cSt.
Other benefits include extremely low vibration, a noise level below 55 dBA, an IP 65 protection rating, and chemical resistant material options.
FP 400 Applications
- Industrial Inkjet Printing
UV Inks, as well as modern printers that require much higher recirculation flow rates, for example the High Laydown (HL) printhead technology - Medical Devices
Temperature management, including aesthetic laser cooling systems - Semiconductor
Temperature management and cooling, especially in systems with sensors sensitive to pulsation - Fuel Cells
Fuel recirculation and membrane hydration
The FP 400 has been intensively tested for 18 months at major printer and ink manufacturers in five countries across Europe and East Asia. The KNF Modular System ensures full customization possibilities and timely response to the market. Please contact us to learn more.
