Metal Bellow seals are ideal for high temperature applications and harsh chemical services where elastomers cannot be used effectively. This seal type incorporates metal bellows as a spring-loading mechanism to maintain face contact when the seal is not pressurized and eliminates traditional secondary sealing requirements.

Types of Metal Bellow Mechanical Seal

In applications where the process temperature exceeds elastomer capabilities, metal bellows mechanical seals with graphite secondary seals are a good sealing option. Metal Bellows Single Seal is designed for high-temperature services typically found in chemical and petrochemical processes. Graphite secondary seals replace O-Rings to achieve the higher temperature requirements. Advanced bellows design distributes pressure uniformly across the span of the bellows plate to reduce stress and minimize weld fatigue. Component design replaces most OEM seals.

Features of Metal Bellow Mechanical Seal

For unstepped shaftsSingle seal, balanced, independent of direction of rotationMetal bellows rotatingAsymmetric bellows form results in even stress distribution with benefits of greater strength and higher rate of flexibilty; seal is bi-rotational and inherently pressure balanced.Smooth profile is resistant to clogging and therefore ideal for slurries and fibrous liquids. Similarly, seal unit is easy to clean and sterilize in place.Unit construction ensures a simple-to-fit seal, with superior heat dissipation paths. Seal unit is reliable and does not wear the shaft.Graphite secondary seals for high-temperature performanceAdvanced bellows design for maximum cycle lifeRotary bellows for enhanced performance in slurry and particulate servicesHydraulically-balanced seal designBlister-resistant carbonProven heat-treated AM 350 bellows constructionGraphite secondary seals for high-temperature performance

Difference between Metal Bellow Seal and Ordinary Mechanical Seal

The welded metal bellows mechanical seal has good floating and random compensation, which can compensate for the leakage caused by wear, axial movement and vibration. Welded metal bellows itself as the elastic element and the sealing function, so there is no need to design the general dynamic auxiliary push ring spring type mechanical seal ring, thus avoiding the fine particles due to dynamic auxiliary seal ring caused by the obstruction, dynamic auxiliary seal and high temperature because of its axial friction resistance reduction the seal compensation ability of the problem.

Metal bellows mechanical seal with no auxiliary seal ring, reduce a leak; at the same time reduce the friction resistance compensation mechanism, improve the following; in the petrochemical industry, welding sealing temperature is not restricted by auxiliary seal bellows; for PTFE bellows seal can be used in the corrosive medium. Its drawback is that some bellows have the smaller elastic force and need to add auxiliary springs.

Welded metal bellows are made by interlacing and closely welding each internal and external diameters of each wave plate, so no matter whether they are used as the stationary or rotary type, it is not necessary to consider the problem of rotation. Welded metal bellows can be made from precipitation hardening stainless steel, high-temperature nickel based materials and chrome-nickel corrosion resistant materials. Therefore, welded metal bellows can be applied to a wide range of temperature (-117 C - 426 C), and various acid, alkali and salt media. The selection of different thickness and layers of the wave plate makes it withstand a pressure of up to 7MPa in a special pump. The design of welded metal bellows seal is generally balanced, so its pressure bears little influence on the surface pressure. The welded metal bellows mechanical seal is not only suitable for nonhydrocarbon media, but also for flash hydrocarbon medium. Compared with the ordinary mechanical seal, its service life has been greatly improved, so it has a higher ratio of performance and price.
