Belzona Facts:

Belzonas solution for acid pumps was originally tested in 1998 on a vertical pump in contact with 93% sufuric acid. Very satisfiying results led to 5 identical pumps 4 years later being protected. Belzona 4311, designed to withstand immersion in such agressive chemicals, once more proved that it is a very cost effective maintenance solution for equipement.
