Dry Gas Seals
HB BSET dry gas seals offer advanced, patented sealing technology in a compact and easy-to-install design. The fault-tolerant design of our dry gas seals offers higher reliability, reduced gas consumption requirements, and allows for gas supply disruptions.
Why Use a Dry Gas Seal ?
Dry gas seals are useful in processes that cannot tolerate any product contamination or escape into the atmosphere. They are also useful for processes or materials that are sensitive to heat that typical mechanical seal faces generate. Dry gas seals use an inert gas to separate the seal faces. The seal faces are profiled to capture the gas and provide lift for seal face separation or light contact. With separation or light contact, minimal heat is generated. The inert gas provides the lubrication for the seal faces and acts as a barrier against the product.
AESSEAL has invested heavily in the development of Gas Seal Technology, that we believe will revolutionise the industry.
This has produced a range of Compressor Dry Gas Seals and Pump Gas Seals. These seals have been designed and are manufactured using our unique modular system, which ensures product quality, continuity and reduced delivery times.
The Gas Seal range has been developed to operate on the most challenging duties with high pressures, speeds and large diameters. Testing on new and current designs is carried out at our dedicated Gas Seal testing facility and this ensures that all our Gas Seal products will exceed your performance expectations.

CAPI-74
Face to Face Category 2 & 3 Seals
The advantages of sealing pumps with dual pressurized dry gas seals are becoming widely recognized throughout industry. AESSEAL® has developed a range of pump dry gas seals to suit every application.
CCS
Conventional Compressor Seal
The CCS™ is a tandem cartridge seal where the inboard seal is designed to seal up to 82 bar (1200 psi), and an outboard seal that acts as a low pressure tandem seal.
HHCS
Hydrostatic Hydrodynamic Compressor Seal
Hydrostatic and hydrodynamic Dry Gas Compressor seal technology, offering robust protection for the sealing surfaces during start-up, shutdown, slow roll and upset conditions.
STS
Mechanical Seal for Steam Turbines
The STS mechanical seal has been developed in conjunction with a major oil refinery to replace existing carbon ring seals normally fitted to steam turbines.
UDGS
Universal Dry Gas Seal
Non-contacting, gas lift dual cartridge seal primarily designed for pumps (ANSI/DIN) providing practically zero process emissions in service. The design ensures long life, low power consumption and reduced capital cost for support systems.
Chamber Shaft Seal RotaSeal KD-3
Chamber Shaft Seal
The high-performance shaft seal RotaSeal KD-3 is an economic shaft seal. Because of its modular system, the single parts can be assembled according to the various operating conditions. Chamber, barrier gas and/ or grease barrier as well as intermediate chamber are designed depending on the special operating conditions.
The respective chamber elements are solid. The shaft seal is formed by the axial screw connection of each chamber element. The chamber elements are delivered including drillings for the holder screws.
The seal elements are multi-part radially cut and are held onto the shaft by the garter spring.
The material of chamber and seal ring is chosen according to the specific operating conditions. The chamber materials are stainless steel, e.g. 1.4571, 1.4021, 1.4539 as well as special materials such as Titan, Hastelloy etc.
The materials for the seal elements can be a variety of PTFE compounds or several artificial carbon qualities.
The RotaSeal KD-3 series is mainly used for the seal of small or middle-sized ventilators, fans, compressors and bearing seals.
Grease chambers do increase the tightness: the grease barriers may reduce the barrier gas volume respectively the leakage by up to 90 %. Barrier gas is indispensable when solid containing media or even toxic media are to be sealed.
As in a modular system, the high-performance shaft seal RotaSeal Type KD-3 can be flexibly assembled from the above mentioned elements for several operating conditions.
The chambers are produced with drillings for the appropriate holder screws. In case of narrow installation spaces, long slots should be preferred.
Chamber Shaft Seal RotaSeal KD-4 HD
Chamber Shaft Seal
The shaft seal type KD-4 HD is a labyrinth seal with solid chambers und seal rings which are radially flexibly mounted.
The seal rings consist of several segments and are kept together by the garter spring. The seal rings are suitable for dry running and do not need any lubrication whatsoever.
The material of the seal ring is chosen according to the operating conditions. Standard material is T10K.
As a wear protection for the shaft, a surface hardness of minimum 60 HRC has to be considered. If the shaft does not have the necessary surface hardness, we recommend a shaft sleeve according to our norm file TWB 2 along with wear protection of quality FMP
65/75. Special shaft sleeves according to customers' specification may as well be delivered.
Chamber Shaft Seal RotaSeal KD-8 HD
Chamber Shaft Seal
The shaft seal type KD-8 HD is a labyrinth seal with solid chambers und seal rings which are radially flexibly mounted. It is especially adequate for the application with extremely high medium-pressure.
The one-piece seal rings consist of a temperature and pressure resistant titan enclosure with seal carbon insert. The seal rings are suitable for dry running and do not need any lubrication whatsoever. The material of the seal ring is chosen according to the operating conditions. Standard material is T10K.
The shaft seal KD-8 HD is suitable for seal the shaft
glands of turbines, compressors and other high-pressure equipments with subcritical and supercritical rotors.
Chamber Shaft Seal RotaSeal GD-2
Chamber Shaft Seal
The shaft seal of our production range GD-2 is a shaft seal in a split case. The applied seal rings are threepiece, radially cut and are radially movable within the housing. Because of the split housing, the installation respectively dismounting is considerably simplified. Special assembly handholds make the handling of big seals much easier. Corresponding mounting threads are foreseen in the housings of bigger dimensions. The layout of the seal, the materials of both housing and seal ring can be adapted to the various operating conditions. The seal rings can be supplied in several PTFE compounds (PTFE with filler materials) as well as in various qualities of artificial carbon.
Chamber Shaft Seal RotaSeal GD-5
Chamber Shaft Seal
The shaft seal of our production range GD-5 is a sliding three-piece carbon seal ring for the application in blowers, agitators, dryers, stirring units, fermenters etc.
The three-piece seal elements are made from PTFEcompound or special carbon and are produced in an adjustable version, i.e. with overlapping mortised, gastight joints. By the garter spring and the existing medium/barrier gas pressure, the seal ring elements are permanently pressed to the shaft respectively the
shaft sleeve. Because of the continuous sliding contact between seal ring and shaft respectively shaft sleeve, latter ones should be furnished with a wear protection.
Chesterton 4400 Dual Concentric Dry Gas Seals
A.W. Chesterton Company has developed technology that makes the use of a dry gas seal easy and intuitive. The 4400 delivers higher reliability with lower gas consumption than conventional gas-lubricated seals. It acommodates loss of barrier gas for greater seal reliability.
Transitions to a traditional liquid seal in the event of the loss of barrier gas and recovers
to a gas seal upon restoring the barrier gas
Compact flush mount design that does not require modification of the stuffing box; fits more equipment types than conventional gas seals
Innovative in-Gland Control System (IGCS) dynamically controls gas pressure to process pressure
Features
Zero fugitive emission, monitoring exempt, dual gas seal design
Full sealing recovering following loss of barrier gas
Unique design minimizes profiled gas face wear due to loss of barrier fluid
Seal transitions to a contacting wet mode during gas disruptions for greater sealing reliability
In-Gland Control System (IGCS) dynamically tracks process pressure to minimize gas consumption
