Smooth Flow Pumps for Demanding Applications
At KNF, the development of a new diaphragm liquid pump starts with looking at the end of the value chain. The inkjet market and the medical sector are good examples of this. What began decades ago with digitally printing ink on paper has evolved into an innovative and expanding industry. Today, digital inkjet printing is used in various applications, including textiles and packaging , printing on ceramics and glass products, electronics, and additive manufacturing. The same is true for the medical industry.
Diaphragm pumps offer many advantages for demanding applications in the inkjet and medical fields. They are clean, oil-free, handle fluids gently and offer outstanding leak tightness. Their ability to move aggressive and abrasive media and their reliable and safe operations are also advantages. As with all positive displacement pump technologies, including peristaltic, gear, and piston, diaphragm pumps generate pulsation. KNF has developed several liquid pumps with minimal pump pulsation using special Smooth Flow Technology.
Why Inkjet Benefits from Smooth Flow Pumps
Diaphragm liquid pumps are crucial for inkjet applications as they must move primers, inks, varnishes, resins or even electrically conductive liquids without compromising their quality. This also includes chemically aggressive or abrasive media such as ink containing particles.Smooth Flow Pumps can add real engineering value in these applications. Some advantagesinclude reduced resistance in the tubing, which is typically only a few millimeters thick and several meters long. Smooth flow increases the efficiency of the pumping process in these applications. It also prevents pressure peaks in the ink system. This is important as, in the worst case, these peaks can affect the quality of the print by disrupting precisely controlled pressure conditions in the print head or by pre-curing inks.
Minimal Pump Pulsation is Crucial for Medical Application
Many advantages of Smooth Flow diaphragm liquid pumps that are critical for inkjet applications are also important for medical technology. Media also need to be transferred in a clean manner, and tubing connections can have similar effects. However, there are more advantages to Smooth Flow Technology that make a difference in medical applications. As many applications are in close contact with patients, pump pulsation can be heard or felt by the patients and may cause discomfort.This can be avoided with Smooth Flow Technology, increasing patient comfort and helping the recovery process.
