The information, provided below, is intended to be used as a general guideline for pump material selection. The 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 21ºC (70ºF), unless otherwise noted. If the fluid temperature differs, from the recommended range, it may affect the compatibility by accelerating the reaction.
*Temperature limits are based on mechanical stress only. Certain chemicals will further limit the fluid temperature range. Stay within the temperature range of the most-restricted wetted component. Operating at a fluid temperature that is too high/low for the components of your pump may cause equipment damage.
**Consult Graco’s Chemical Compatibility Guide. This guide is intended to be used as a general guideline for pump material selection. If you are unsure of the compatibility of your chemical, we recommend testing a sample of the material in question with the chemical.
***The specific gravity of a liquid or solid is defined as the ratio of the weight of a given volume of the material to the weight of an equal volume of water. s.g. = (weight of a given volume of material) / (weight of an equal volume of water).
