Plant in one of the biggest open-pit mine operations on the planet have to handle the exceptionally poor and aggressive quality ofwater. This article discusses how a combination of a pump shaft upgrade and the use of non-galling advanced thermoplastic represented a huge improvement in the pump performance.
For any new project, engineering and mining companies select their pumping equipment for some very specific duty conditions and fluid characteristics. How ever, when months and years go by, some of these variables start changing, such as the pipeline internal diameter or the percentage of solid concentration in the fluid, which can impact pumps heavily and even experience catastrophic failures if no corrective measures are taken. This is certainly not desirable for the end-user, asit operation does not perform as planned, nor the pump manufacturer that usually receives negative reviews of its product…
