Application Scenarios  Bellow Type Mechanical Seal

Centrifugal and Reciprocating Thermal Oil Pumps

Metal bellows seals will have a higher performance when compared to elastomers for centrifugal thermal oil pumping systems and thermal oil recycling processes. After prolonged operation in both applications, metal bellows seals will maintain a consistent face loading through both thermal expansion and thermal contraction.

Chemical Processing Pumping Applications

Applications using metal bellows seals include any chemical processing system that adds solvents and aggressive materials into their system. These seals have corrosion resistant materials allowing for their extended use in media that may otherwise destroy conventional sealing products.

Vacuum Systems and Low-Pressure Process Applications

Low leakage rates and reduced out-gassing risks make the use of metal bellows seals particularly useful in vacuum furnaces and semiconductor manufacturing and laboratory research equipment.

Petrochemical Refining Applications

The typical combination of high temperature cycles and hydrocarbon process media creates a considerable amount of damage through face loading on the seal and metal bellows seals allow for a significant amount of thermal fluctuations and produces less thermal deformations leading to seal failure.

Electric and Gas and Energy Generation Applications

Metal bellows seals have been found useful with many types of power generation applications including boiler feed water pumps, turbine auxiliary systems and any rotating equipment operating under high temperatures or varying loads.
