Pump <strong>Repair</strong><br />
Products: Titanium Putty / Ceramic <strong>Repair</strong> Putty /<br />
Application Date: Brushable Ceramic<br />
Application Customer: Date: 6/1/90<br />
Customer: Industry: Pennsylvania Electric Company<br />
Industry: Utility Power Generation<br />
Problem:<br />
This multi-stage cooling pump would receive extreme abrasive <strong>and</strong> cavitation wear to the spicket fits, hub<br />
area, flange <strong>and</strong> casing. The wear was so severe the pump efficiency was reduced by 50%. The previous<br />
method of repair was to simply replace when required. Replacement cost was estimated to be 28K.<br />
Solution:<br />
Complete repair areas were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. All surfaces were chemically<br />
cleaned using Cleaner Blend 300. Titanium Putty was applied to the spicket fits to replace or rebuild<br />
missing metal. Titanium was smoothed <strong>and</strong> contoured using Acetone <strong>and</strong> a putty knife following gel<br />
point. Titanium Putty was also used in the same way to rebuild missing metal on the hub <strong>and</strong> flange areas.<br />
Ceramic <strong>Repair</strong> Putty was applied to cavitated areas deeper than 1/4”. Following a partial cure of Ceramic<br />
<strong>Repair</strong> Putty <strong>and</strong> Titanium Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in<br />
two 15 mils coats. Brushable Ceramic provides a long lasting, low co-efficient to friction, protective<br />
surface coating.
