6.2.6 Internal coating
If the pump has an internal coating, this coating
must be inspected periodically. Any wear or
cracks of the coating found must be immediately
repaired. Failure to do this may lead to accelerated
wear of the coating during operation and corrosion
of the exposed base metal, depending on the
material and pumped liquid. Special attention must
be paid to the coating edges. Any loss of coating
material is considered to be normal wear and tear
on the pump and is not considered as warranty.
Flowserve has applied the coatings according to
the supplier's instructions but will not be held
responsible for coating wear or cracks that may
develop over time
.
