COMPATIBILITY CHEMICAL COMPATIBILITY Chemicial Compatibility Guide The following information is intended to be used as a general guideline for pump material selection. The information accuracy of these ratings cannot be guaranteed, nor is it a complete list due to the extensive area of this field. Materials used in the pump and pumping systems must be chemically compatible. The data provided for the chemicals is at 70ºF (21ºC), unless otherwise noted. If your temperature differs from this, it may affect the compatibility of the fluid with the given pump materials by accelerating the reaction. If you are unsure of the compatibility of your chemical, we recommend testing a sample of the material in question with the chemical. Updated 10/29/2024
