The upgrade of the outer magnet ring on the CS pump range offers significant advances in magnetic coupling robustness leading to increased MTBF (mean time between failure), reduced downtime / increased uptime and increased operational efficiency.
The retro-fittable outer magnet ring (OMR) provides shielded magnets that retain the same level of performance and eliminate any potential for damage. The new OMR has improved cyclic thermal duty whilst the identical coupling power produced means that the upgrade maintains similar performance to maintain reliability.
The encapsulated magnets on the OMR are made of samarium cobalt and have increased resistance in corrosive applications. They also provide higher efficiency by reducing slip and improved reliability because no tie bolts are used in the retention of the magnets.
This upgrade is straightforward as no specialist tools are required and is recommended as the current magnets used in the CS pump are becoming obsolete and so no longer available as spare parts.
With increased safety due to there no longer being a remote possibility for the magnets to come into contact with the containment shell, this upgrade is recommended for all current CS pumps.
