KNF, Spider-jet Partnership Powers Custom Inkjet Solutions
Custom KNF diaphragm pump solutions help Italian startup Spider-jet complete solutions in plotter and single pass digital inkjet printing technology
Spider-jet, an Italian inkjet printing startup, focuses on innovative plotter and single pass technology for industries requiring custom solutions. They rely on KNF pumps in all their systems to meet their customers’ needs. KNF pumps are known for their performance and reliability. These custom diaphragm pump solutions have a proven record of success across a variety of industries, including Spider-jet’s inkjet printing technology.
Managing Aggressive Media
KNF diaphragm pumps, most notably the NF 60 and NF 25, are a critical part of every one of Spider-jet’s system lines. These dry-run safe, self-priming pumps are available with a variety of motor options. Both can be produced using chemically resistant materials and can achieve maximum flow rates of 0.6 l/min or 0.25 l/min respectively.
They are responsible for two primary functions. The first is loading ink from canisters to the main tank. While this is a simple task, it requires a pump that can handle aggressive or abrasive materials often encountered in inkjet printing applications.
Pumps like the NF 60 are ideal for this function, as they can be custom fitted with FFKM diaphragms. These diaphragms are softer and can resist abrasive inks containing solid particles. They are also chemically resistant to solvents, a necessity in inkjet printing systems where these solvents are common.
The NF 60 is an important piece in Spider-jet's cutting edge printing systems. It features optional diaphragms made from chemically resistant materials.
Keeping the Ink Flowing
The next function is in the ink recirculation system, a key part of any inkjet solution. To avoid precipitation of heavy components, it is critical to keep the ink in continuous motion. That is where KNF pumps come in. The NF 25, with its consistent and reliable performance, is particularly well suited to this task.
In Spider-jet systems, ink needs to be recirculated indefinitely. This helps to prevent particle precipitation, which is common in these applications. FFKM diaphragms are also typically required. This, coupled with the required flow rate to maintain continuous circulation, is why Spider-jet relies on the NF 25 for ink recirculation systems.
Customized Solutions for Customized Products
Spider-jet systems are custom designed for various industries where unique processes are required. As such, KNF’s custom-designed diaphragm liquid pumps are ideal for their systems. Spider-jet engineers have continued to work with KNF to refine and perfect their systems.
Some potential changes include the incorporation of NF 100 pumps where higher flow rates are necessary. This state-of-the-art pump achieves a maximum flow rate of 1.2 l/min and is available with the chemically resistant FFKM diaphragm materials required of inkjet printing applications.
FP 70 and FP 25 are also being introduced into Spider-jet systems. These Smooth Flow pumps have integrated pulsation dampers, allowing for greater controllability of ink flow. They offer up to 10 times lower pulsation compared to conventional pumps. This is especially critical in inkjet systems. It allows the FP 70 and FP 25 to serve as a replacement for gear pumps in these applications.
