Edge welded metal bellows are manufactured by microscopic welding of stamped metal diaphragms. Male and female diaphragm plates are stamped from rolls of sheet metal stock. Inner diameters of the male and female diaphragm are then welded to form a convolution. Repeated process of welding convolutions at their outer diameter forms a bellows core. The bellows core can be welded to end fittings to complete the bellows assembly.
Bellows for Mechanical Seals
Metal bellows in mechanical seal ensures dynamic sealing along with a defined pre-loaded spring force.
Double ply design for high pressure applications.
Sliding surfaces can be offered in Carbon, Silicon carbide, Tungsten carbide, Ceramic and composites.
Bellows for Vacuum Valves
Metal bellows provide effective stem seal for valves in vacuum applications.
Very high flexibility and reliability over a large number of cycles.
Customized bellows designed to fit your valves.
Bellows for Accumulators and Reservoirs
Used for energy storage or pulsation damping in hydraulic systems.
Metal bellow isolates gas & liquid compartment of an accumulator. Storage pressure is increased or decreased by pumping liquid in or out of the accumulator.
Metal bellow accumulator completely eliminates use of elastomeric or wearing seals ensuring zero leakage and no seal wear providing completely maintenance and service-free operation.
Bellows for Manipulators and Feedthrough
Precise positioning and movements in vacuum applications are achieved through metal bellow manipulators & motion feedthrough.
As a flexible sealing element, metal bellow allows linear, angular and lateral movements while maintaining a high degree of vacuum.
Bellows for Sensors and Actuators
Metal bellows instead of traditional piston can be used to generate force or movement. Hence, they can be used as sensors and actuators.
Metal bellow offers combined sealing and actuation effect.
Careful selection of materials ensures consistent performance characteristics.
