Robust bellow seal with non-DIN cross-section, available inthree standard DIN working lengths and with stationaries to suitall common European housing sizes.

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.

Bellows Mechanical Seal are a type of mechanical seal where the spring element is a bellows. This eliminates the need for a secondary dynamic seal e.g o-rings. Bellows Mechanical Seals are also known as non-pusher seals as they have a static secondary seal which stays in place against the shaft, sleeve or on the gland of the pump.

A bellows mechanical seal is used where a dynamic seal is deemed unsuitable for the application e.g high temperature medium slurry or high seal hysteresis.

The primary mechanical seal functions exactly the same as a standard mechanical seal except the spring element is now being replaced with a bellows. The friction from the dynamic seal (e.g o-ring) is not a consideration.

However if a bellows mechanical seal should fail it can be due to several reasons such as; poor wielding, product particulate getting into the bellows and causing the spring element to fail, chemical and/or abrasive attack or over-pressure.

The Rubber Bellow Mechanical Seals is designed to protect the top entry drives in glass-lined vessels. The Rubber Bellow Mechanical Seals are compact in design that is mainly used for any mixed and pressurized liquid in vessels where the leakage cannot be tolerated. The Rubber Bellow Mechanical Seals comes with seat rotating, stationary springs, a standard version with grooves, and many others.

These series of seals are used for plain shafts, these are single coil Unbalanced seals having elastomer bellows and are Independent of direction of rotation.

Rubber Bellow Mechanical Seals can be use regardless of direction of rotation since the driving torque is not transmitted through the coil spring. The required driving torque is through the spring and spring holder.The single coil spring will avoid effluent particle.

Rubber bellow Seals are used in slurry, Alkaline and base medium. It will work in dual direction. It can be used as a double mechanical seal by back to back arrangement. The seals are recommended with pure medium without solid contaminations

Regarding seal construction, We hold expertise in offering a wide range of the product. These are admired for their robust design and high functional efficiency. Our seals are acclaimed for their various salient features. These are made from the top quality components, these seals are acknowledged for their assured quality and reliability. And the seal has following special featuresLonger service life

Asymmetric 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.

It is easy to occur coking and carbon deposition at the trough between the wave plates, which makes the bellows lose elasticity and cannot compensate, so it can not be used for coking, carbon deposition and crystallized precipitation pump.

For external installation mechanical seals, the sealing surface can be pushed open when the pressure in the sealing cavity is more than 0.2MPa. This is because the elastic force of the bellows is small and can not withstand the high pressure of the medium. Therefore, it is not possible to use an external bellows mechanical seal when the pressure is high.

Because the metal bellow type mechanical seal is a balanced structure, the effective diameter and load factor must be calculated in use. Otherwise, in the high-pressure propane and propane pump, the phenomenon of "spray leakage" is easy to occur.

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.

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.
