Inflatable seals work by introduction of an inflation pressure into the cavity of the inflatable seals. This inflation pressure causes the displacement of the seals effecting a positive seal between the seals and the surface to be sealed. Once the seals inflation pressure is removed the seal returns to its uninflated position
Inflatable seals work by introducing inflation pressure into their cavity, causing the seals to displace and create a positive seal against surfaces. Regulated air is commonly used as the inflation medium. Inflatable seals offer versatile configurations in radial and axial directions. They are made of silicone or other materials and can accommodate variable sealing gaps by inflating. When pressure is removed, they return to their original shape.

Mechanical seals are used to prevent leakage at the point where a rotating shaft passes through a pump casing. There are several types of mechanical seals classified by their sealing method - dynamic seals include labyrinth, carbon ring, gland packing, and mechanical seals. Mechanical seals have no leakage and low power loss, making them commonly used on centrifugal pumps. API standard 682 governs the selection and operation of mechanical seals for pumps handling fluids from -30°C to 260°C and pressures from 0-34.5 bars. Key components, materials, balancing methods, and failure causes were discussed in the presentation. Steam traps are also presented as devices that discharge condensates from steam systems while retaining steam to improve efficiency.
The Linuo butterfly valve uses a triple offset design that provides tight shut off and minimal friction. As the valve begins to open, the disc moves away from the seat, resulting in less friction, wear, and torque compared to traditional butterfly valves. The triple offset design also allows the valve to achieve tight shutoff even at low pressures or reverse flow. Butterfly valves are also lighter and more economical than equivalent ball valves.
A mechanical seal is a sealing device which forms a running seal between rotating and stationary parts. They were developed to overcome the disadvantages of compression packing. Leakage can be reduced to a level meeting environmental standards of government regulating agencies and maintenance costs can be lower.

What is and what is the function of a rubber seal
The Increasing of the speed of mechanical systems, driven by the desire for greater productivity, leads to higher operating temperatures and reduced fluid viscosities. This, coupled with higher pressures, causes an increasing tendency for fluid to leak. This leak in fuel systems that handle highly flammable solvents cannot be overlooked as there is a high probability of a fire hazard.
For this reason it has become common practice to include a safe leak path in the system design, to an escape or collection point, in order to minimize risk.
Seals prevent fluid from escaping from a hollow cylinder when a shaft penetrates the cylinder wall. Most commonly, the axis will have a rotary or linear motion. If a seal is not made for functional requirements, or installed and maintained properly, it can fail, causing fluid loss. The two main functions of a seal are to keep the fluid in while keeping dirt and debris out.

Advances in Spray Dry Nozzle body sealing with C&DStuart Morgan
The document discusses advances in spray dry nozzle sealing technology. It describes the limitations of traditional radial seals, which require a gap and are prone to failure under pressure spikes. The new "Click & Dry" nozzle uses two independent compressive axial o-ring seals with no gap. This eliminates the need for expensive and troublesome backup rings to support the seal. The axial face-to-face sealing arrangement of Click & Dry can withstand far greater pressures than radial seals and has a longer service life by protecting sealing faces during assembly and cleaning. Various worldwide sealing standards limit the safe operating pressure of radial seals without backup rings, showing the advantages of Click & Dry's gap-free design.

1. Inflatable seals work by introduction of an inflation
pressure into the cavity of the inflatable seals. This
inflation pressure causes the displacement of the seals
effecting a positive seal between the seals and the
surface to be sealed. Once the seals inflation pressure is
removed the seal returns to its uninflated position
(memory).
Regulated air is the commonly utilized inflatable seals
medium while in some applications pnuematic (gas) or
hydraulic (liquid) methods are suitable. Inflatable seals
offer versatile configurations in three different planes:
radially in, radially out, and axially.
Inflator-seals are an inflatable silicone seal (like a door
seal or aperture seal) that can be inflated to
accommodate a variable sealing gap.
We manufacture inflatable seals and inflatable silicone
seals in a relaxed/deflated attitude but when air
pressure is applied, the seal either expands or rises up
to meet the sealing face. When the pressure is released,
the seal returns to its relaxed position.
West Polymer Products Pvt. Ltd. seals are made from
high strength FDA approved silicone and are supplied in
our corporate colours of transperent & red favoured by
the food industry. Other colours are available to special
order.
Fabric reinforced inflatable seal
Non reinforced inflatable seal
3. Sliding doors - a great benefit for this application. The seal
automatically retracts away when air pressure is removed,
allowing the door to travel freely.
Pharma-Copia Environments - inflator-seals provide an
inflatable sealing solution where the risk of fabric
contamination is unacceptable like fluid bed dryer, processor
& coaters.
Food Processing - ideal for oven door seals. In the event of
accidental damage, the colour of the seal ensures that
detection in the event of contamination is easily achieved.
Inflatable seals are fitted in the following cases where
sealing handling, or locking is required.
Movable cofferdam bulkheads
Storage containers
Transport containers
Leaktight panels (naval, aerospacial industry)
Nuclear vessels (equipment or personnel chambers)
Isothermal chambers
Clean rooms
Sliding or quick-locking doors (autoclaves, sterilisers)

Application
4. When free, WESTERN POLYRUB seals must not be inflated above ≥ 0,8 to1,5 bar (according to the type of the profile).
When fitted in a groove, they are perfectly leaktight for an inflation pressure of 1,25 to 1,45 times the pressure to
seal (Ps). The maximum
inflation pressure (Pi) which the seals can withstand depends on the clearance (J) between the supporting frame and the
moving panel (see profiles on pages 4-5). The inflation pressure (Pi) can be higher if clearance is reduced. seals are
designed to provide tightness on pressurised equipment. This creates a lateral force on the seal, which tends to force it
either towards the outside (equipment under pressure) or towards the inside of the equipment (equipment under
vacuum).
a)Equipment under vacuum (P0-Ps>0)
The condition of the surfaces in contact, as well as the completion of the assembly operation, make it possible for seals to
withstand a vacuum of 10-3
Torr (dynamic vacuum).
b)Equipment under pressure (P0-Ps<0)
With an internal pressure created by gas or a controlled atmosphere, the strength is directly linked to the clearances,
deformation of the contact faces and the pressurisation of the seal. In these applications, it is always necessary to
reduce dimension (J) to a minimum, restricting the surface to which the pressure of the enclosure (Ps) will be applied, in
order to reduce the radial component or, depending on the arrangement, the axial component, as far as possible as this
tends to force the seal outwards. Generally, the ratio Ps-Po/Pi is of 0,7 to 0,2 but with the limits laid down in the table
concerning profiles (pages 4-5).

Inflatable seals are made by joining together extruded or moulded sections. This connection is made in our workshops,
which ensures perfect continuity while at the same time reducing any stresses in the joint to a minimum.
This method provides substantial flexibility with regard to the geometry of the sections. There are t w o types of standard
profiles and a series of special profiles that are used in numerous applications, i.e. sealing, locking or gripping during
automatic handling have beencreated.
For specific uses which need reinforced manufacturing (textiles, hight performance aramid fibers) or expanded profiles, see pages 12
and 13 and please contact our technical department.
seals have no textile reinforcement or expansion system. Their expansion, like their retraction, is obtained
through the combined effects of the walls of the seal forming elastic arms. The seals, which are produced
from elastomers with a high modulus of elasticity and considerable elongation and fitted in grooves, are
restricted to low work rates. As a result, they are protected against risks of bursting, so it is necessary to
observe the fitting dimensions (table, pages 4-5).
Comment: inflatable seals must be captive in slots or grooves closed on all four faces in accordance
with the specified dimensions. You are strongly recommended not to pressurise or use the seals
when one of the faces
of the groove is open. On the other hand, seals can be secured by their base and work freely. However, the
maxi- m u m pressure cannot be applied until their contact face (toothed side) is against the item to be sealed.

9. TYPES OFELASTOMERS
WESTERN POLYRUB inflatable seals are produced with elastomers with high mechanical properties.
Silicone, SBR and EPDM are the most commonly used. Although these are high performance
materials, they are not suitable for all applications, and consequently, other elastomers should be
used.
*Profiles not kept in stock, produced on special request. (Please contact our technical department).

END PLUGS
Linear seals may be manufactured with “solid” end plugs. In this case, the plugged areas are neutralised, as
neither expansion nor contraction can occur.
Two constructions are possible: either by plugging the expanded seal or by plugging the retracted seal. When
using either solu- tion, it is necessary to provide flanges or end plates to hold the seal in order to prevent
tearing caused by seal expansion (see flanges or retaining plates below).
Note : The dimension N represents the intermediate part be- tween
the active seal and the end plug which cannot come into contact
with the face to be sealed. The efficiency of the seal is only obtained
beyond L + N.
These parts must not be outside of the support face seals under any
circumstances.

13. POSITION OF FITTINGS ANDVALVES
Inflatable seals conception requires that connections be located at the bottom of the grooves or at the
end of the seals (straight length). When seals have curves radii it is preferable to avoid connections located in the
curved area. If the equipment around the seal for assembly or other reasons requires a lateral supply, it is possible to
use elbow fittings or special constructions (please consult our technical department).

Note : For REC, REF, REP fittings, and CVL valves, please consider the size of the thread part (M) as the connection
diameter (see sketches on page 7). In case of intermediate value (dimensions in inches), take the next larger cone. (For
other sizes, please con- tact our technical department).
ASSEMBLYCONDITIONS
For a maximum binding (metal/rubber), the fitting
valves are
equipped with a overmoulded rubber cone in
accordance to their diameters (see table below).
SURFACEFINISH
The mean roughness obtained by machining (lathe,
mill, etc.) must not be less than the value of 0,8 to 1,6
microns Ra (L.C.A. Rugotest, standard N6 - N7).
Applications where high performances are not
required, 3,2 microns Ra are permissible (standard N8,
L.C.A. Rugotest). Transverse scratches and local
damage to the bearing surfaces to be sealed are
prohibited.
PREPARATION OF GROOVESAND
CONTACTFACE
Before installation, it must be verified that the
groove taking the seal is free from roughness
(grit or weld spat- ter, flash or projections sharp
edges). If roughness occurs, this must be taken
off before the installation, followed by
degreasing with a suitable solvent.
INSTALLATION
1/ - The seal must be absolutely free from internal
pressure at the time of fitting. If the valve is equipped
with its mechanism, this must be removed during
installation.
2/ - The installation of the seal in the groove must start, by
position- ing the pressure connexion (fittings or valves)
in the (in) housings, then, the mechanical fixing is
operated. It is important to make sure that splice
vulcanisation is located far from the curve area.
3/ In order to fit the seal correctly, it is necessary to
pressurise it immediately after positioning it in the
glued groove, while observing the operation
recommendations, i.e. perfectly captive on its four faces.
4/ It is possible to leave the CEFIL’AIR®
seal pressurised
throughout the time necessary for drying or vulcanizing
the adhesives ; it is also possible, after a short drying
time, to retract it in order to complete the setting
operation. However, it must only be moved after the
bond is completely fixed.

ASSEMBLYCONDITIONS
FIXING THESEALS
Although inflatable HP seals can be fitted in grooves without any form of retention, it is preferable to glue
them to the bottom of the grooves. For this operation, it is recommended to use our general-purpose
adhesive which can be applied directly to the metal when it has been thoroughly degreased and is free from
rust or scale. For intensive utilizations of inflatable seals, we advise to prepare the support by a sanding
process and to use the sticking primary (i.e. PM 820) and the silicone (RTV). If a different product than the one
recommended is used, please check the instructions manual.
HP seals must be secured by the
part opposite that of the seal
(bottom
of groove only), avoiding the
use of adhesives on the
lateral parts.
LP seals will preferably be
fixed mechanically, but, if
an adhesive is necessary,
the gluing must be limited
to the foot of the profile.
FIXING THE PRESSURECONNECTION
The housing hole needs to have a conical part
according to indications on page 9, to receive the
overmoulded rubber cone of the seal. In the case of
threaded connections (REC, REF, REP, CVL) tightening
must be moderate and during this operation it is
absolutely necessary to maintain the connection in
order to avoid damaging the link between metal and
rubber. It is important not to apply any torque to the
fitting.

PRESSURESUPPLY
Inflatable seals can be supplied either with gas or fluids. However, it is necessary to provide a constant supply, which
must be guaranteed by a pressure regulator to avoid overpressure. Due to the relative permeability of elastomers (when
inflated with air or gas) notably for silicone, it is necessary to provide pressure regulation for this type of inflation. It is
also possible to use fluids (water, oil, etc.) to prevent elastomer gas permeability. (Please contact our technical
department).

CALCULATIONS AND SUPPLY
APPLICATION FORCE (CALCULATIONS)
seals are retracted even with a residual internal pres- sure.
Their expansion occurs above the latter and brings the
contact and sealing face against for the moving part. The
pres- sure necessary for expansion varies a little over a
whole range of arrangements and depending on the
profiles used. In the majority of cases, the minimum
operating pressure is 1,5 bar.
The inflation of the CEFIL’AIR® seal provides an application
force proportional to a unit contact surface. The total
applied load (Fj) for the seal on the moving panel will be
determined by:
