Belzona Provides Corrosion Protection on a Brand New High Pressure Pump
Belzona - providing solutions to industry for 60 years through industrial protective coatings and polymer repair composites has a recently undertaken an application to provide corrosion protection and increased efficiency to a pump casing and impeller.
A global producer and supplier of high-quality farmed salt water fish in North Wales, contacted Belzona looking for a reliable corrosion protection system. Application services division of the Belzona Group, Belzona Technosol Limited provided a full supply and application service ensuring the pump was back in service within 3 days.
Once the pump unit was high pressure washed and blasted to a substrate cleanliness of at least SA 2 1/2 and a surface profile of no less than 75μm it was found that the main areas of damage were the impeller and the volute casing.
The first stage of the application was to coat the internals of the pump casing and the impeller with two coats of Belzona 1341 (Supermetalglide) a high performance coating for improving the efficiency of fluid handling systems and protection of all metals from the effects of erosion-corrosion.
The second stage of the application was to apply a protective coating to the externals of the pump casing. The Belzona 5811 (Immersion Grade) system was ideally suited to this application as it demonstrates outstanding protection from the effects of salt water and the environment and was designed for substrates operating under immersion conditions in contact with aqueous solutions.
The total cost of this repair was a fraction of the cost of a new replacement and the epoxy based coating supplied by Belzona will offer resistance against corrosive attack in the future.
