India is the not only the largest consumer of sugar in the world, it is now also the largest producer of sugar, displacing Brazil. The Indian sugar industry is the second largest agro-based industry in India.* With this in mind, our partners in India, Kirloskar Corrocoat, regularly work with clients in the sugar industry, providing refurbishment, repair and corrosion protection for plants and ancillary equipment. Kirloskar Corrocoat have applied Fluiglide E to more than 500 pumps in the sugar industry: providing improved efficiency, along with corrosion protection to considerably extend the life of the pumps.
Fluiglide was featured in the product showcase in the last edition of Corrocoat News (the May 2022 issue). These energy-efficient products maximise the performance of pumping systems used in power generation cooling water systems, water & waste treatment and process industries worldwide. They also provide an effective corrosion barrier, preventing early fall-off in performance due to nodular growth, corrosion and surface roughness.
Kirloskar Corrocoat recently worked with a client/sugar factory in the populous state of Maharashtra. They took on a project to refurbish and protect 5 injection water pumps (ranging from 6” to 16”) with Fluiglide E, with the aim of improving overall efficiency.
The below images show the top and bottom casing and the impeller.
Note, the wear ring portions and bore ID area were totally damaged by erosion & corrosion. The hydraulic portion of casing was in a heavily damaged condition.
For the refurbishment work, the internals were grit blasted in accordance with ISO-8501 to Sa2 ½ surface finish, and then coated using Fluiglide E, applied by brush to a minimum DFT of 1.2mm. The pitting and cavities were filled with Corrocoat EA; a viscous, solvent-free, high build, two pack epoxy coating with excellent erosion resistance, toughness and outstanding anti-corrosive properties. The internals were then spark tested at 10kV.
The externals were also grit blasted to Sa2 ½ surface finish and coated with a standard epoxy paint for aesthetic effect only, as requested by the client. Bearings and wearing rings were replaced, and the pumps were then reassembled using new fasteners, gaskets and fixings.
