Belzona Facts:

The customer saved $15,000 and the application took 3 days to complete. The customer wanted to try Belzona on this casing since previously they were only getting 3 months of service out of the casing. This pump was coated a year prior with Belzona. When they opened in January 6 months later it still looked just like the day it was coated. That’s when they decided to coat all their pumps with Belzona.
