Peristaltic pumps pumping water based ink gently
Pumping ink from storage containers to the rollers on printing machines was proving problematic for the Danish company, Peterson Packaging. Air diaphragm pumps were responsible for the job but had proved unable to pump the water-based ink gently enough. As a result bubbles formed in the ink, ruining the packaging, creating excess waste and adding expense.
To resolve the problem Peterson Packaging researched the market for a gentle-action pump to ensure bubble-free ink. The chosen design also needed to be both cost effective and sufficiently compact to fit into the limited space available.
The Verderflex Dura peristaltic pump proved the ideal solution. Ink is completely contained within the tube pump’s hose which is compressed by a rotating roller. On restitution of the hose the resulting vacuum draws in more liquid, creating a gentle and accurate pumping action. The design eliminates any danger of cross contamination or spillage.
One of the most advanced peristaltic pumps on the market, the Verderflex Dura has a unique design that provides a 70% smaller footprint to similar pumps. This was an important attribute for Peterson Packaging as it required five peristaltic pumps to fit in a tight space at the end of each print line.
As well as overcoming the space constraints the Verderflex Dura hose pumps are now delivering important performance benefits for Peterson Packaging. In addition to transferring bubble-free ink, the peristaltic pumps are proving very easy to clean and maintain. They can even run dry without fear of damage. Downtime is greatly reduced as the only wearing part is the hose. Colour change of the inks is also quick and easy.
Peterson Packaging confirms that the pumps are certainly proving more efficient and quieter to run than their unsuitable and expensive forerunners. “We are very happy with the Verderflex Dura pumps and have now installed a total of 15 units into our printing process,” the company’s engineering manager concluded.
