Belzona Facts
In 2007 the customer asked for renewal and protection of pump casings with Belzona® 1311 and Belzona® 1321. After 4 years in service the casings showed no significant wear. The customer was convinced of the quality of Belzona and ordered the renewal and protection of the impellers with the same Belzona system.
