Style 558-559
Mechanical Seals Multi Spring
Pusher
type rotating seal with a PTFE wedge sealing on the shaft. This PTFE wedge
retains the sealed fluid and follows the seal movement to compensate for
shaft run-out and end play. This extremely effective seal designed to meet
API standard and featuring multiple spring action, is suitable for a wide
range of applications, particularly in refineries and petrochemical process
plants. It is available in both metric EN 12756-L1K and imperial (inch)
sizes. Style 558 uses an elastomeric O-Ring instead of a PTFE wedge. Available
upon request in balanced configuration 558B - 559B.
