bellow mechanical seal supplier
A Bellows seal does not have a secondary seal that must move along the shaft or sleeve to maintain seal face contact. The secondary seal is static state at all times, even when the pump is in operation.
Primary seal face wear is typically accommodated by welded metal or elastomeric bellows which move to assist in the compression of the rotary to stationary seal faces.
Bellows seals allow for high and low temperature applications when used in conjunction with metal bellows. They do not require a rotating secondary seal, which means it is not prone to secondary seal hang-up or fretting along the shaft or sleeve.

John Crane brings you the world’s most complete selection of performance-proven edge-welded and formed metal bellows sealing products used in a wide range of rotating equipment such as pumps, compressors, mixers, and agitators. Our experience in diverse industries such as oil & gas, petrochemical, chemical, refrigeration compressor, pharmaceutical, food processing, pulp & paper, and more have proven the soundness of John Crane’s metal bellows design.
Yes, Flexaseal’s edge-welded bellows are completely manufactured at our Vermont factory. Our welding department and engineering staff work closely together to control the manufacturing quality of all bellows assemblies, from stamping sheets of foil stock through welding cores and end fittings, evaluating spring rates, and pressure testing the completed assembly. We use the TIG (Tungsten Inert Gas) welding process which provides the finest control of the weld arc, resulting in efficient, clean, and long-lasting welds.
Formed bellows are manufactured from either welded (seamed) or seamless tubing and utilize extensive automation for mass production. This process offers some cost benefits over edge-welded bellows assemblies however, formed bellows are limited to materials which can be elongated through either rolling or hydroforming. Formed bellows typically have thicker convolution structure with higher spring rates and larger deviations than edge-welded bellows which impacts precision loading.
Flexaseal designs and manufactures edge-welded bellows. Our bellows production begins by stamping male and female diaphragms from sheet (foil) stock. We inventory foil stock including various Hastelloy™ and Inconel® grades, titanium and Monel® as well as cryogenic-grade materials, to accommodate a wide range of applications. Diaphragms are TIG-welded together to create a convolution, and these convolutions are assembled together and welded to create the bellows core. Bellows core sizes can range from just a few welded convolutions to 100+ convolutions for a hermetic bellows assembly.
Contrary to popular belief, it is possible to repair a rotary bellows assembly. If pressure testing reveals leakage around the seal face, Flexaseal will de-insert the current face and check the retainer for any damage. If the retainer is within the necessary tolerances, FAS will insert a new face into the assembly as well as replace the other wear parts (O-ring and hardware).
If the bellows rotary shows visible damage to either the bellows core or end fittings, or a pressure test reveals leaks in the assembly itself, Flexaseal recommends a new bellows assembly to ensure sealing integrity.
In a pusher seal design, the secondary sealing component – usually an O-ring or a wedge — must move axially to compensate for wear, vibrations, and movements of the shaft.
Welded bellows assemblies also offer the benefit of an inherently balanced seal design. Mechanical seal balance refers to the ratio of the opening and closing areas of the seal faces. Both a balanced and unbalanced design may have the same opening face area but the balanced seal’s closing area is smaller, reducing the load on the faces. This reduced load means less heat generated at the seal faces, enabling the balanced seal to run cooler than an unbalanced seal design. This cooler operating environment positively impacts a seal’s run time.
If your facility must comply with API Standard 682 which requires all Type B or C cartridge seals to utilize a balanced seal design, standardizing on hydraulically balanced, welded metal bellows seals ensures satisfactory seal run time and low seal maintenance for your equipment.
Operating length (OL) - also referred to as installed or working length: The axial length of a bellows assembly as installed to the designed compression. The term may also refer to the dimensional range within which a bellows assembly can safely be operated.
Mechanical seals, whether a pusher or bellows design, need a specific amount of compression to ensure the faces are in contact to maintain the correct amount of lubrication to operate (dry-running seal designs are the exception to this statement.) Both the Free Length and Operating Length are necessary for this compression calculation: Free Length – Operating Length = amount of compression. Here’s an example:
We recognize and understand the vital role of metal bellow mechanical seal in their application. With purposes including securely fastening components within systems, and contaminants prevention such as gases and liquids from navigating through enclosed and sealed areas. That is why we offer wholesale metal bellow mechanical seal in different variations and diversities to ensure the integrity and efficiency of systems they will be applied to will function successfully and optimally. The different seals" types available include static that does not move along with other seals and dynamic seals that move collaboratively.
Depending on the industry and selected purpose, we consider metal bellow mechanical seal requirements. Requirements are like pressure, that is pressure changes, to ensure they can withstand and do not deform by the sealed fluid, the load and how it can withstand deflection, dynamics such as the alignment and vibration, and temperature covering the environmental conditions and the heating arising from the friction of the seal operation and fluid movement.
The seals are either bolts, nuts, or washers. Seal bots are commonly used because of their benefits in being reusable, preventing fluids and contaminants from escaping even under high pressure. Nuts are essential on temperature withstanding and compatibility with screws, studs, and bolts, in addition to, easy installation. Moreover, washers can withstand high pressures and are compatible with other seals.

A Metal Bellow Mechanical Seal is a kind of seal that is mainly used in the process of containing fluid, especially from pumps and mixers. The mechanical seal is much needed so as to seal between the shaft and the pump housing so that it can help in containing the pressure of the pump. The bellow mechanical seal can help in withstanding the friction caused by the shaft rotating.
These kinds of bellow mechanical seals are characteristically working towards maintaining the strength between friction faces. The Metal bellows mechanical seal comes with some advantages and in relation to conventional spring systems.

Elastomer bellows mechanical seal is identified by the use of a unique elastomer bellows or diaphragm for the secondary sealing part, which provides a high degree of axial flexibility to compensate for lack of concentration of the shaft & misalignment & wear due to thrust movement of the shaft.
Elastomer bellow seal is the most commonly and generally used rubber bellow seal, due to its compact design, easy installation, mass production and low cost.
Elastomer seal is non-directional, technically advantageous and extremely versatile. Elastomer bellow seals can be used regardless of the direction of the rotation since the driving torque is not transmitted through the single coil spring. The required driving torque is enhanced through the rubber bellow which fits on the shaft through the interference fit between the collar, rubber bellow, and shaft.
