Belzona Facts:

Regional waste water authority routinely replaces its pumps, as it has been unsuccessful with previous coatings to protect against erosion and corrosion of entrained solids through its waste pumping system. Coating will allow client to continue using more cost effective steel castings instead of looking at more exotic alloys. The easy application of the Belzona 1321 in two colors and two coat system allows the internal maintenance team to complete the repairs internally and observe the level wear before it becomes critical.
