The technology has come off the age and proved to enviormental protection system. is devoted standard for mechanical seal. The new sealing technologies are based on advanced computerprograms used to optimize the seal design. Combined with advancement in the seal face materials theequipment availability and reliability has increased substantially. other related standard are : API 610,DIN 24960, ISO 3609, DIN EN 12756 and ISO 21049.
API 682 standard
Seal Balancing : for seal to perform, the seal faces must be incontact with each other in dynamic conditions. Theheat generation due to interface pressure load mustnot vaporize the liquid film. seal balancing is ageometrical feature provided to seal face thatavoids such condition.
.
Sealing Mechanism : Two Lapped faces, one
rotating with shaft and another stationery in
gland are brought in contact with each other by
means of spring force. the surfaces are seprated
by micron thickness of film of fluid being sealed.
The generation of this film is automatic due to
micro asperaties on the lapped surfaces thus
the film acts as a lubricant and reduced the
friction and heat generation well within the limit
of seal face material. Generally the lubrication
regime is mixed one. Typical coefficient of friction
is 0.07 for general purpose seal and 0.015 for
well designed high pressure seals.

SEALING TECHNOLOGY
www. microseals.com
ELASTOMERS Generally seal face materials easily withstand hightemperatures, typically 330 C. However tempraturelimitation on the part of secondary elastomers decide theseal temperature capability so while selecting the sealthese limits are to be taken in to account
.MATERIALS
Most of the seal designs have stood the test of timeand are still in regular usage. The improvements,however have been tremendous in the seal facematerials. The development of superior and highlyreliable resin impregnated carbon as also antimonyimpregnated carbon has enable suucessful sealoperation even in marginal lubricantion conditionsparticularly in light hydrocarbon and high temperaturewater applications.
for corrosive liquids resin impregnated carbon andsintered silicon carbide grades have proved the idealsolutions. the hardness and thermal conductivity ofsilicon carbide is extremely high as shown in thetable below

Seals Repairs & Refurbishment
Seals Repair TipsIf your pump seals are in need of repair, we canbring them back to “Like new” condition
If you use seals, you know reparing them caneasily save you 50% of the cost of a new seal.with the exception of the most common the “throwaways”, Repairing Seals will save your money.
Our Strength :
We repair all brands, and all styles of MechanicalSeal from all seal manufacturers including but notlimited to John Crane, Flowserve, Chesterton,AES,Flex-A-Seal, Burgmann, Robco, Us-Seal Etc.
We are Specialized in handling Repairing of allmakes and models of Agitators, Mixers, Reactors,Atomizers and centrifuges, (Any size Variation)
Repaired mechanical seals can also upgraded by replacing carbon faces with Silicon Carbide or Tungsten Carbide for much less than upgrading toa new seal.
Repairing Process
We have a fully operational workshop wherewe reconditional all types of mechanical sealsif the condition allows giving the mechanicalseal or components a second life.
All seal components are completely cleaned,measured, pressure tested, and inspected bythe enginerring department to determine whichparts can be re-used or require replacement.
All of the seals we repair are cleaned or sandblasted, inspected for factory tolerance, receivenew faces if required (otherwise lapped), newsprings, new elastomeric (rubber boot or O-rings),new set screws, new setting clips (if a cartidgeseal), lapped to industry standards (2-3 lightbands) assembled Re - inspected and shipped.
Ship your seals to us so that we can provide youturnaround service within few days.
We offer our support in the assembly andstart-up of more critical systems.
We are able to evaluate worn-out seals andto refurbish quickly and economically.
Our experienced Engineers, appropriatemachines and equipments, enables us toquickly point out the root cause accurately.We conside all aspects of the seal conditionand operation hiistory to determine the rootcause of any problems.
