Spray-coat the inside wall of the pump casing and, in particular, the impeller
clearance areas with a preservative.

2.
Flush and clean the pump, particularly if it has been used for handling noxious,
explosive, hot or other hazardous fluids.
3.
If the pump has handled fluids whose residues could lead to corrosion damage
in the presence of atmospheric humidity or could ignite upon contact with
oxygen, the pump must also be neutralized, and anhydrous inert gas must be
blown through the pump to ensure drying.
4.
Always complete and enclose a certificate of decontamination when returning
the pump.
Always indicate any safety measures and decontamination measures taken.
