Verderflex has exported 30 of its VF hose pumps to Morocco. The models are said to reduce downtime, minimise maintenance costs and ensure the reliable pumping of abrasive, corrosive, viscous and high-density fluids. The pumps were ordered to fulfil an essential role in the refining of cobalt. Principally, the pumps are being used to transfer sulphuric acid and ammonia solutions from storage and dilution tanks to reactors and baths. These solutions are used in electrolysis, a process whereby the cobalt is rinsed to eliminate impurities and separate it from other ore components such as nickel, iron and arsenic. Exact dosing of the sulphuric acid in accordance with the pH value of the mined cobalt is vital to ensure its purity and concentration. To achieve this, the capacity of the Verderflex pump is automatically adjusted by a frequency controller that is driven by a pH meter. The VF pump is suitable for such an application as the absence of product slip in the hose gives a 100 per cent...

Peterson Packaging, a Danish printing company, has selected the Verderflex Dura peristaltic pump to gently handle water-based ink. Transferring ink from storage containers to the rollers on printing machines was proving problematic for Peterson. Air diaphragm pumps were originally responsible for the job, but had proved unable to handle 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, the company decided to look 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. With the Verderflex Dura peristaltic pump, ink is completely contained within the 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 process. The design eliminates any danger o...
