Aura™, the next generation of John Crane Gas Seals, reduces operational and transactional costs using a patented polymeric sealing device. Leakage rates are reduced 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.
Aura provides the ultimate reliable operation in temperatures ranging from -58°F to 392°F/ -50°C to 200°C and pressures up to 3190 psi (g)/220 bar (g).
Just some of the parameters of the dry gas seals include:
- Temperature limits: -58°F to 392°F/ -50°C to 200°C
- Pressure limits: up to 3190 psi (g)/ 220 bar(g)
- Speed limits: up to 459fps/140m/s measured at balance diameter
- Size limits: for shaft sizes up to 10.25”/260mm, corresponding to seal sizes up to 12.125”/307.9mm
