Watson-Marlow manufactures tubing in four materials for peristaltic pumping and transfer duties. The company can supply tubing in 12 different materials and over 60 sizes. Chemical and abrasive resistant Marprene, Sta-Pure, Chem-Sure and Neoprene tubing are suitable for applications including beverage dispensing, industrial washers, automotive, ink and chemical transfer, abrasive, aggressive, acidic or caustic-based fluids.

For hygienic applications, Pumpsil is a high-grade silicone tubing manufactured to extremely tight tolerances. Laser traceability provides lot number, part number and use-by-date laser-etched into the surface of Pumpsil silicone tubing. This feature meets all the necessary requirements for validated processes. For greater chemical compatibility, Marprene and Bioprene thermoplastic tubing is FDA-approved and offers a long life.

The right choice of tubing material, together with the correct bore to wall thickness ratio, are the criteria which determine consistent throughput and long tube life in all applications. In peristaltic pumps, a new tube is a new pump. Peristaltic technology ensures that the pumped fluid never comes into contact with any other part of the pump than the tube, guaranteeing safety and the integrity of the fluid.
