Under
high pressures and velocities, the LKS Seal™ guards against extrusion of the seal
jacket material by supporting it in hardware with little or no clearance
between the seal and rotating shaft. The seal's unique
design forces the wear pattern of the jacket material to take place
at the lip contact area, not the hinge point.
This ensures longer life
and superior sealing performance. The LKS Seal consists of a
Canted-coil™ spring-energized,
graphite-reinforced
PTFE sealing ring coupled
with a high-temperature
engineered thermoplastic
anti-extrusion element and
a metal locking ring.
Features
Benefits
All-in-one configuration
Eliminates costly assemblies/assembly error, simplifies maintenance and replacement, provides compatibility with conventional gland configurations
Built-in thermoplastic anti-extrusion element
Minimizes seal jacket extrusion, provides longer sealing life, forces wear to occur at lip contact area, not hinge point, extends seal performance range at low and high temperatures (-94ºF to +550ºF).
Graphite-reinforced PTFE sealing ring
Retains ability to seal in high-temperature, high pressure service conditions at
moderate speeds, provides high level of extrusion resistance, long-wearing properties and built-in lubricity.
Hastelloy® Canted-coil™ spring
Exerts uniform sealing force against the shaft, lowers frictional contact at the lip area (reducing heat build-up and extending seal life), provides excellent
corrosion resistance/chemical compatibility.
Bottom line?
If you're looking for a better, more efficient way to seal in high pressure, high velocity applications, you've found it. The LKS High PV Seal leverages the best in design material properties to outperform and outlast other sealing solutions by up to 150%. And it's available right now.
