BELZONA® 1341 IMPROVES SWIMMING POOL PUMP PERFORMANCE
Industry: Water / Wastewater (WATR)
Application: CEP-Centrifugal Pumps (CEP)
Substrate: Cast Iron casing / Bronze impeller
Customer Location: Swimming Pool, BC, Canada
Application Date: August 2006
Belzona® 1311 (Ceramic R Metal)
Belzona® 1341 (Supermetalglide)
Problem: Erosion corrosion, aggravated by galvanic corrosion and corrosion from pool chemicals had reduced pump performance.
- Pump casing prior to application
- Impeller prior to application
- Pump casing after application of Belzona® 1341
- Pump impeller after application of Belzona® 1341
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 was carried out in accordance with a Belzona Know-How System Leaflet CEP-1 & 10.
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%.
