Application Situation
Because of the dissimilar metals (Bronze and cast iron) making up the pump components, the facility would only get one year of operation out of a pump.
Application Method
Application was carried out in accordance with a Belzona Know-How System Leaflet CEP-1 & 10.
Belzona Facts
Apart from the general erosion corrosion problems experienced with swimming pool pumps, improving pumping efficiency and reducing running costs were becoming more important as energy costs continue to escalate. An application of Belzona® 1341 Supermetalglide to the internal surfaces of the pump increased the efficiency by almost 12%.
