The type 580 is a welded metal bellow seal that doesn’t have dynamic o-ring on shaft and can avoid the leakage problems due to the hanging of elastomer on the shaft. The bellow form gives a good balancing factor to the seal. This seal can work with high and very low temperature or viscous liquids and slurries.
