Edge-Welded Metal Bellows Seals
Low-Temperature and High-Temperature bellows seals assure low emissions and optimized
Mean-Time-Between-Planned-Maintenance (MTBPM).
• Superior Bellows Design
These seals are manufactured with a 45º tilt edge at the bellows' inside
diameter to disperse stresses and maximize operating life.
• Superior Plate Shape
The plate shape used by FBU is called a nesting ripple. With a
three-sweep radius, this plate design allows the bellows device to be flexed
repeatedly without the metal being stressed beyond its endurance limit.
• Self-Cleaning Design
Rotating bellows throw off suspended particles that clog spring-type seals.
This self-cleaning action eliminates the need for external flushing, filters or
cyclone separators and their associated costs.
• World-class Bellows Manufacture
Our bellows production facility has an outstanding manufacturing process with state-of-the-art stamping,
welding and testing technology.
• Application Flexibility
A wide range of metallurgies, face combinations and packing materials are used to seal a variety of
demanding applications.
