Customer: Industry: Eurocan Pulp<br />
Industry: Pulp <strong>and</strong> Paper Manufacturing<br />
Problem:<br />
After only a short service life this Bingham pump casing would received extreme abrasive <strong>and</strong> cavitation<br />
wear from processing wet pulp stock. The wear was so severe that the pump would require replacement<br />
every 3 years. Pump replacement cost was estimated at $60K.<br />
Solution:<br />
Complete pump casing was s<strong>and</strong>blasted to a SP5 white metal finish. Exp<strong>and</strong>able metal was tack welded<br />
to areas of extreme wear. Exp<strong>and</strong>able metal improved mechanical bonding properties of Titanium Putty.<br />
Welding slag was cleaned using a grinding machine. Surfaces were chemically cleaned using Cleaner<br />
Blend 300. A thin 10 mil coating of Brushable Ceramic was applied as a primer to thoroughly wet out<br />
the pump surface area. Titanium Putty was applied to rebuild all areas of extreme wear <strong>and</strong> wear ring<br />
seat areas. Ceramic <strong>Repair</strong> Putty was applied to cavitated areas deeper than 1/8”. Following a partial<br />
cure of Ceramic <strong>Repair</strong> Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in two<br />
15 mil coats.. Brushable Ceramic provides a long lasting, abrasion <strong>and</strong> chemical resistant, low coefficient<br />
to friction protective surface coating. <strong>Devcon</strong>’s repair cost was $4K.
