This tool is intended as a general guide for pump material selection. It includes many common liquids used in chemical, paint, industrial and food processing applications. It has been compiled using many sources, all believed to be reliable. However, the information cannot be guaranteed.
Due to the extensive scope of this field, the tabulation is not complete, nor is it conclusive. Corrosion is the destructive attack of metals by chemical or electrochemical reaction with its environment. Corrosion rates vary widely with concentration, temperature and the presence of abrasives. Impurities or other trace elements common in industrial liquids may inhibit or accelerate corrosion. Aeration or deaeration of the substance being pumped can also affect rate of corrosion. Materials used in the pump and pumping systems must be chemically compatible.
Elastomers are subject to destructive attack by chemicals or solvents. Attack may be evident as hardening, swelling, loss of elasticity, increased permeability, or more subtle changes.
