Always make an immersion test before choosing a tube material for critical applications. Immerse a short length of the tubing (always available from Watson-Marlow Fluid Technology or its distributors) in a closed container of the fluid for 48 hours, and then examine it for signs of attack, swelling, embrittlement or other deterioration.
*Important note - The ReNu Pumphead contains lubricant. It is the user’s responsibility to comply with local health and safety regulations, including ensuring chemical compatibility between the lubricant and the duty fluid before use. The standard lubricant is silicone oil. A glycerol/glycol blend lubricant is also available as an option. Contact your local Watson-Marlow representative for guidance.
*The information contained in the chemical compatibility guide is believed to be correct. Watson-Marlow Fluid Technology Group accepts no liability for any errors it contains. It is the users responsibility to ensure chemical compatibility within their application.
