Problem:<br />
A high solids slurry combination of water <strong>and</strong> coal ash would cause severe abrasive wear to this bottom<br />
ash transfer pump housing. Previous method of repair was to simply replace the pump housing when<br />
required. Pump housing replacement cost was estimated to be $30K.<br />
Solution:<br />
Pump housing was s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Complete repair area was then<br />
chemically cleaned using Cleaner Blend 300. Ceramic <strong>Repair</strong> Putty was applied to rebuild wear ring<br />
seats, fill holes <strong>and</strong> repair eroded areas deeper than .125”. Ceramic <strong>Repair</strong> was allowed to partially<br />
cure for 4 hours. Wearguard Fine was applied to a thickness of between 1/2” <strong>and</strong> 1-1/2” depending on<br />
the depth of wear. Acetone was used to smooth <strong>and</strong> feather Wearguard Fine following gel point.<br />
Following a 4 hour partial cure of Wearguard Fine, Brushable Ceramic was applied to a thickness of 30<br />
mils. Brushable Ceramic encapsulated the repaired areas, <strong>and</strong> provided a protective coating to the<br />
remaining exposed edges. <strong>Devcon</strong>’s repair cost was $1K.
