Process Equipment Update
Peristaltic pumping offers a host of advantages over conventional pumping techniques, especially when coupled with the latest control technology. Sean Ottewell reports.
Peristaltisches Pumpen bietet jede Menge Vorteile gegenüber konventioneller Pumptechnik, insbesondere, wenn es mit modernster Kontrolltechnik gekoppelt ist. Sean Ottewell berichtet.
Le péristaltisme présente de nombreux avantages par rapport aux systèmes de pompage traditionnels, d’autant plus s’il est accompagné d’une technologie de contrôle sophistiquée. Selon Sean Ottewell.
Peristaltic pumping tackles tricky processing problems

Fig. 1. The Flexicon PD22I has overcome a host of processing problems, including contamination and slow product changeover.
ompared with lobe pumps, diaphragm pumps, gear pumps and piston pumps, and every other type of pump, the advantages of peristaltic pumps are many, including no
contamination of the fluid being pumped, no contamination of the pump itself, ideal for shear- sensitive and aggressive fluids, dry-running, no valves/glands/seals, and reversibility. One of the latest companies to avail of these
benefits is London, UK-based Wine Innovations, the inventor, founder and pioneer of ‘the tulip’ pre-filled wine goblet. The company is now using industrial peristaltic filling machines from Flexicon Liquid Filling, part of the Watson-Marlow Pumps Group, on its latest filling lines.
Having originally used volumetric filling equipment, the company is enjoying a vast array of benefits from its switch to Flexicon technology. The tulip itself is a pre-filled and sealed shatter-
proof plastic wine goblet (187ml) for outdoor events such as concerts, festivals, sporting events, parties and fairs. Its advantages include rapid serve time, no spillage or waste, safer than glass and full recyclability.
Growing take-up Now the company is finding additional success as a convenient solution for airlines, ferries, hotel mini bars and railways. With its one-year shelf life, there is also growing take-up from retail outlets. The original volumetric filling machine was
