Peristaltic pumps are currently used for the filling of food, medical, pharmaceutical and industrial products. In particular, they are used in bottling lines of flavorings, acids, bases and, in general, foaming liquids containing impurities in suspension. There are two types of peristaltic pumps normally used in this application: O.E.M. pumps integrated in a central control system and stand-alone independent pumps. The integration of O.E.M. pumps allows manufacturers of automated systems to fill with good repeatability, quickly, easy change of the worked product and maximum cleaning. The use of independent pumps enables users to fill, easily and with reduced costs, particular or dangerous liquids, increasing the safety and repeatability factors.
