Brushable Ceramic Blue
Epoxy Coat™ 7000 AR
In mines, water feed pumps “wear” because of abrasive particles flowing through the volutes at tremendous speeds, causing wear and abrasion inside the volute and impeller areas. Pump casings are very expensive and instead of “replacing” the volutes, metal-filled epoxies are used to rebuild loose metal. These polymers act as better “wear resistant” finishes on the surface. In this pump, the volute areas had wear up to 1” deep, which had to be filled before a protective coating could be applied.
The volute of the pump casing was sandblasted to an SSPC-SP5 white metal finish. After blasting, the pump was cleaned with our Cleaner Blend 300 to remove all residual abrasive shot from the surface. Then a primer coat of Brushable Ceramic (12-15 mils) was coated on all areas. Immediately after coating with Brushable Ceramic, the large voids (over 1” deep), were filled with Wear Guard High Load. The Brushable Ceramic acts as a primer helping the beaded epoxy adhere better to the surface. Next, Ceramic Repair was used to fill all other voids (under ½” deep). Finally, a topcoat of Brushable Ceramic (12-15mils) was used for a smooth, final chemical resistant finish.
