The Smooth Flow promise from KNF

Maximum ink supply reliability with KNF's low-pulsation Smooth flow diaphragm liquids pumps.

Smooth flow pumps with low pulsation, developed a few years ago by KNF and already well established in the digital printing market, are ideal for achieving a constant and homogeneous flow of large volumes of ink.

The FP series with liquid flow rates of up to 5 l/min and the FK series with flow rates above 12 l/min significantly reduce pulsation compared to conventional single-head pumps, making them a valid alternative to gear pumps.

In keeping with the evolution of the digital printing market, the company strives to constantly improve its technological proposition by offering customers increasingly innovative and highly efficient systems.

Diaphragm liquid pumps for maximum ink supply reliability

Digital inkjet printing systems combined with liquid diaphragm pumps are being used in many different areas of application, from textiles and packaging through to ceramics and glass.

All of these applications require fluids such as primers, inks, varnishes, glazes, coatings or even electrically conductive liquids to be available at the print head in the right quantity at the right time, and without compromising the quality of the fluid.

KNF diaphragm liquid pumps are ideal for these applications as they handle fluids very gently, ensuring that their specific characteristics do not change. They can handle chemically aggressive or abrasive media such as ink containing particles with ease. This is important in terms of service life and reliability of a printing system.

Multi-diaphragm technology

By interlacing the flow and the pulses generated by each of the diaphragms, a very high and yet smooth flow is achieved in the diaphragm liquid pump.

This helps to efficiently transfer liquids through long hoses with smaller diameters as Smooth Flow pumps reduce pressure loss. This innovative technology also minimises hose vibrations which might impair print quality.
