√ Stationary designs well fitted for large shaft and high speed application
√ Ideal for cryogenic and high temperature condition, normally the quench system is required with steam at high temperature to avoid coking, and nitrogen is used at cryogenic services to prevent icing;
√ Special design for non-compensation ring structure to avoid stress deformation of faces;
√ Standardized bellows manufacturing process with high strength and fatigue resistance
Features:
● Welded metal bellows, stationary
● Shrink fitted seal face
● Flexible graphite as secondary seal
● Standard floating bushing
Recommended applications:
√ Cryogenic and high temperature
√ Refining & petrochemical
√ Coal chemical
