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.
