Pump <strong>Repair</strong><br />
Brushable Ceramic<br />
3-15-99<br />
Syncrude, Ft. McMurray<br />
Mining<br />
Problem:<br />
In mines, water feed pumps “wear” because of abrasive particles flowing through the volutes at<br />
tremendous speeds, causing wear <strong>and</strong> abrasion inside the volute <strong>and</strong> impeller areas. Pump casings are<br />
very expensive <strong>and</strong> instead of “replacing” the volutes, metal-filled epoxies are used to rebuild loose metal.<br />
These polymers act as better “wear resistant” finishes on the surface. In this pump, the volute areas had<br />
wear up to 1” deep, which had to be filled before a protective coating could be applied.<br />
Solution:<br />
The volute of the pump casing was s<strong>and</strong>blasted to an SSPC-SP5 white metal finish. After blasting, the<br />
pump was cleaned with our Cleaner Blend 300 to remove all residual abrasive shot from the surface.<br />
Then a primer coat of Brushable Ceramic (12-15 mils) was coated on all areas. Immediately after coating<br />
with Brushable Ceramic, the large voids (over 1” deep), were filled with Wear Guard High Load. The<br />
Brushable Ceramic acts as a primer helping the beaded epoxy adhere better to the surface. Next, Ceramic<br />
<strong>Repair</strong> was used to fill all other voids (under ½” deep). Finally, a topcoat of Brushable Ceramic (12-<br />
15mils) was used for a smooth, final chemical resistant finish.
