New from peristaltic pump specialist Watson-Marlow Pumps Group is a high performance, long life tubing ideally suited to harsh chemical applications.
The GORE High Resilience Tubing: Style 400 is an expanded PTFE multi-layer tubing featuring high performance Viton filler that is able to maintain a stable flow rate for thousands of hours while pumping aggressive chemicals. This construction makes the new tubing suitable for a range of aggressive chemicals such as concentrated acids as well as aromatic hydrocarbons.
At continuous pressures of 4 bar, consistent flow rates are achieved throughout the lifetime of Style 400 tubing. While chemicals will attack most other types of tubing, the resilience of Style 400 is provided by Viton GF-600S, a peroxide-cured fluoroelastomer based on DuPont advanced polymer architecture. Performance testing shows that compared with conventional non-reinforced extruded Viton or Fluorel tubing, Style 400 extends the tube life by more than 50 times. The new tubing also offers superior burst resistance.
The tubing is currently available with internal diameters ranging from 1.6 to 12.7mm, with wall thickness from 1.6 to 4.8mm.
