Application Situation
2-stage Pemo pump with heavy leaching.
Application Method
All components of the Pemo Pumps were previously grit blasted according to SA 2½ / 75µ. After grit blasting, the components were immediately re profiled with Belzona 1111 and Belzona 9341. This process was repeated several times to achieve the original size. After re-profiling, the parts were turned to the original size on the lathe. After the re-profiling was completed, the pumps would be coated with Belzona 1321 Grey and Belzona 1341 Blue. Application was carried out in accordance with Belzona Know-How system leaflet CEP-3
Belzona Facts
A quick solution with the Belzona products prevented a longer downtime of the system. By re-profiling the Pemo pumps, the system could be put into operation again after 2 weeks. Due to the longer delivery times for new parts from Italy (3 months), the customer decided to reprofile and coat the pumps. The customer saved approx 120,000 Swiss Francs (Approx £94,000 GBP)
