Belzona Facts:

The alternative to a Belzona repair is replacement which is considerably more costly, and takes several weeks for delivery. Similar repairs had already been carried out for this customer so belzona was obvious choice as not only is time and money saved but the life and performance of the pump is extended. This application can be performed at a cost of approximately $15,000, and returned to service within one week.
