Pump Liner <strong>Repair</strong><br />
Flexane® 80 Liquid & Putty, Irathane® 155HS<br />
May 2002<br />
South American Copper Mine<br />

Problem:<br />
These Warman® pump rubber liners suffer a lot of wear because of the severe operating conditions<br />
in mineral pulp. The cost of replacement is extremely high.<br />
Solution:<br />
The surface of the liners was hydroblasted to give it a good profile for the repairs <strong>and</strong> to<br />
decontaminate it. Then it was cleaned with <strong>Devcon</strong> Cleaner Blend 300. UU-66 primer was applied<br />
<strong>and</strong> allowed to dry. Then Flexane Putty <strong>and</strong> Liquid were used to rebuild the worn geometry of the<br />
liner. Once this repair cured, the substrate was again primed with UU-66 <strong>and</strong> 4 mm of Irathane<br />
155HS polyurethane was applied to even out the surface <strong>and</strong> give it greater abrasion resistance.
