7.1.13 Preassembly inspections
7.1.13.1 Reconditioning
After disassembly all parts must be cleaned and checked for wear carefully. Worn or damaged parts
must be replaced by new parts (spare parts).
It is recommended in most cases to replace mechanical seal, ball bearings and seals (flat seal, O-rings).
NOTICE:
All PTFE sealing elements and graphite seals are intended for being used only once.
In most cases it make sense, if damaged absolutely necessary, to renew the mechanical seal and the
bearings Deposits on the impeller (230), in the volute casing (102V) or on the casing cover must be re-
moved.
