Which pump seal material should I choose?

Pump Seal Material Compatibility

Choose a pump seal material that is compatible with the chemicals you will use. Chemical incompatibility can cause accelerated wear and equipment failure that is not covered by warranty, so it’s important to do your research.

  • Consult the safety data sheet (SDS) for your chemical to learn about the ingredients.
  • Use a chemical compatibility database (like this one: https://www.coleparmer.com/Chemical-Resistance) to look up the ingredients and find material compatibility info.
  • Note that the concentration of chemicals makes a big difference in compatibility. Think about whether the chemical you use will be in a pre-diluted or concentrated form when it is used in the equipment.
  • If you need help, ask your chemical manufacturer. Or, send your SDS to techsupport@foamit.com and we can help.
