This month Watson-Marlow will be unveiling its latest pumps designed for the food industry, the 720 range, which, along with the 520 and 620 models, come with a five year warranty, a first for the peristaltic pump industry, the company says.rnThe 720 models, which are being shown for the first time at the Carrefour des Fournissiers de I'lndustrie Alimentaire show in Rennes, France, are said to have a smaller footprint than other industrial pumps with a similar flow rate. This is 2,000 litres an hour for single channel versions or twice that for double channel models.
