Replacement new vertical storm water pump
Application Method

Belzona Facts
City personnel were very unhappy with the short service life of original vertical storm water pump. To protect the new pump from the damaging effects of the erosion corrosion cycle, Belzona coatings were applied. The new pump was retired after 10years of successful service to replace it with a larger pump. An after service inspection revealed that 100% of the Belzona® 5811 was intact and 95+% of the Belzona® 1321 was intact.
