Technical Description Mechanical seal ISaura 120ns
iseal isaura dry gas seals are designed to reduce seal-operating and
transaction costs by implementing a common design approach across
the range and delivering extended maintenance intervals. The new isaura
120NS provides solutions for compressor applications with small crosssection
cavities.
• Wider performance envelope, including bidirectional operation
• Increased reliability for extended maintenance intervals
• Improved design for simpler serviceability
Design Seal Isaura 120ns
- ISaura 220: Silicon carbide rotating and stationary sealing faces, springenergized-
polymer secondary sealing for high-pressure duties
to 250 bar static pressure - ISaura 120NS: Silicon carbide rotating and stationary sealing faces,
spring-energized-polymer secondary sealing. This latest design delivers
up to 120 bar static pressure with 42% reduced radial cross section and
25% reduced axial length to fit smaller compressor seal cavities.
ISaura reduces operational and transactional costs using a patented polymeric sealing device. isaura reduces leakage rates by up to 15 percent, lowering the total cost of operation while protecting the environment. An enhanced rotor design extends scheduled maintenance periods, and the optional bi-directional capability reduces the need for an extensive spares inventory.
isaura provides the ultimate reliable operation in temperatures ranging from -58°F to 392°F/ -50°C to 200°C and pressures up to 3625 psi (g)/250 bar (g).
With isaura, operators gain access to localized technical expertise from the largest global service network in the industry with over 300 service engineers located worldwide. Technical support and troubleshooting from service and reliability experts is available on the widest range of applications in the industry.
