For lower sealing pressure
applications, dirty gas applications, retrofits
for eductor labyrinth seals that are not meeting
EPA VOC emission standards, oil free screw compressors
with limited radial space, centrifugal compressors,
Kaydon's economical K-MRC seal has become the
seal of choice.
K-MRC seals can handle dirt and liquid contamination
without catastrophic failure of the seal. No large
rotating masses to create rotor dynamic issues.
Lower initial cost than dry gas face seals but
with buffer gas consumption rates comparable to
face seals. Can't justify a dry gas seal conversion
with your budget limitations? Consider the K-MRC
with economical Kaydon support panels. Enjoy significant
HP savings compared to an oil seal and the elimination
of oil management issues. Running with carbon
bushing rings now? Pay for the K-MRC seals with
reduced buffer gas usage. When it does come time
to rebuild the seal, seal repair kits make the
job quick and economical. Bi-directional designs
provide further savings in your spares investment.
Small radial profiles will allow
the K-MRC to retrofit an existing eductor labyrinth
shaft seal eliminating emissions, in most cases
without machining of the compressor casing or
seal housing. Also ideal for oil free screw compressor
seal housings where the radial space is limited.
Seal arrangements can accommodate the use of filtered
process gas or any other clean gas source as the
purge gas. Standard arrangements include seal
redundancy and barrier seal features. Available
design options allow sealing pressures up to 350
psi. Seal arrangements are customized to your
compressor, process requirements and purge arrangements.
The seal is installed in
a single cartridge, pre-tested at your application's
design speed and differential pressure.
No other manufacturer can match Kaydon's 20+ years
experience supplying circumferential sealing technology
for compressor applications in services including
refinery wet gas and cokers, propane refrigeration,
styrene off gas, hydrogen, natural gas, carbon
dioxide and iso-butane to name a few.
Kaydon understands
the necessity for quick response, without cutting
corners. Kaydon does not subscribe to the "black
box" approach to seal repair. Interested
in what was wrong with your seal or what caused
a particular problem? Let Kaydon schedule a live
video conference to show you the internals of
your seal, what was wrong and discuss what the
solution will be. If you don't have video conferencing
facilities available, we will e-mail photographs
within 48 hours of our receipt of the seal.
Need help pulling your seals for inspection or
installing your new seals in the compressor? Kaydon's
turnkey field services will provide the on-site
personnel to do the complete job.
Circumferential seals consist of
segmented carbon rings that run in contact with
a rotating shaft sleeve. The light contact loading
allows minimal seal gas flow during the initial
years of installation. As wear does occur, eventually
the segments will become archbound and the seal
continues to operate as a clearance seal with
minimal seal gas flow rates. When you want to
restore the seal like new, carbon kits are available
to rebuild the seal. The only rotating component
of the seal is a shaft sleeve with a hard coating
that the carbon segments run against.
