Problem:<br />
This stainless steel water circulation pump impeller received extreme cavitation from processing high<br />
velocity cooling water. The pump could not be removed from it’s operating position. This required the<br />
repair be completed in wet conditions <strong>and</strong> in an overhead position.<br />
Solution:<br />
The damaged areas on the impeller blades were roughened by h<strong>and</strong> using a wire brush. Complete repair<br />
areas were then pressure washed with distilled water. Surface area was then chemically cleaned using<br />
Cleaner Blend 300. Underwater <strong>Repair</strong> Putty was applied to damaged areas, covered with pliable plastic<br />
paper, <strong>and</strong> compressed or formed. The plastic paper protected the Underwater <strong>Repair</strong> Putty from being<br />
eroded by the continual flow of water while curing. Following a 2 hour cure of Underwater <strong>Repair</strong> Putty,<br />
the plastic was easily peeled away.
