KHIA ID: 9029

Industry: Marine (MRNE)
Application: CEP-Centrifugal Pumps (CEP)
Substrate: Other

Customer Location: Houston, TX
Application Date:

Products: Belzona 1331, Belzona 1814

Problem: The client had used weld overlay in the past to build up the worn dredge pumps once they hit their limit. This was a slow, expensive, and inconvenient process due to having to ship them to FL to have the exotic metal welded.

Belzona 1814 applied to all wear areas of the pump

Application Situation

Belzona was a cheaper and faster alternative to the weld overlay of the exotic Ni-Hard metal overlay. Taking 3 days to complete vs 2 weeks. This allowed the client to stop from shipping the pump across the country and also get it back in service in 1/4 of the time

Application Method

Pump was brought to the shop
SP10 minimum 3-mil blast
"Priming" coat of 1331 was applied to help with increasing shear adhesion of the 1814
1/4" of 1814 applied to the entire pump internals.

Belzona Facts

The client wanted to find a faster way of protecting their dredge pumps vs weld overlay. Belzona became the solution with excellent documented testing on abrasion and a fast turnaround time to get the equipment back online and running.
