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.
