Problem:<br />
Primary first stage pump impeller would receive extreme wear from processing raw sewage <strong>and</strong> other<br />
foreign materials. Past pump repair method was to simply replace the worn impeller when required.<br />
Impeller cost was estimated to be $5K.<br />
Solution:<br />
Impeller was s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Complete impeller was then chemically<br />
cleaned using Cleaner Blend 300. FL10 Primer was applied <strong>and</strong> allowed to cure or dry for 15 minutes.<br />
FL10 Primer improved the chemical bonding properties of the epoxies used. Ceramic <strong>Repair</strong> Putty was<br />
applied to rebuild all worn <strong>and</strong> cavitated areas deeper than 1/8”. Following a 4 hour partial cure of<br />
Ceramic <strong>Repair</strong> Putty, two 15 mil coatings of Brushable Ceramic were applied. Brushable Ceramic<br />
provides an abrasion <strong>and</strong> chemical resistant, low coefficient to friction protective surface coating.<br />
<strong>Devcon</strong>’s repair cost was $200.
