The pumping fluid can sometimes wash out or extract certain elements from the metal in the piping, pump and seal components.

Some types of de-ionized water have been know to leach out copper from the piping and deposit it between the lapped seal faces where it caused a premature seal leak.

Other types of de-ionized water have leached out carbon from the seal face leaving a weakened structure behind.
