Ground wires must be connected to the piping and any other peripheral equipment. When operating the
pump make sure it is properly grounded. Otherwise friction between the parts and abrasion caused by
some fluids flowing inside the casing may generate static electricity. In addition it may cause fire or
electric shock, depending on the type of fluid being pumped and the installation environment (such as
gases in the air or the surrounding mixtures).
