(1)Features
• Non-contact type barrier seal
• Gas-lubricated
• Bi-directional
• Ready-to-fit cartridge unit
• Equipped with Espey carbon rings type WKA400
(2)Advantages
The service-proven bearing oil seal with moderate levels of
buffer gas consumption. Non contact type carbon rings are
segmented rings hold together by a garter spring at the
outer diameter. A defined minimum radial gap provides a
contact-free operation. The gas consumption can be
considered as moderate. The seal is sealing the oil
properly and has proven to be very robust and reliable
even at extreme conditions.
(3)Operating range (see note on page 1)

Barrier gas supply pressure: min. 3 bara (43 PSI)
Operating pressure: 0.05 ... 11 bara (0.7 ...159 PSI)
Sliding velocity: 0 ... 100 m/s (328 ft/s)*
Temperature: -20 °C ... +100 °C (-4 °F ... 212 °F)*
Barrier gas: Air or nitrogen

no limitations
Run-out of shaft: max. 20 μm*
Vibrations peak/peak (in the area of compressor bearing):
Smax = 3.5 x 25.4 12.000/nmax
Smax = 275 μm (short term)
* Can be exceeded with adjusted design
(4)Materials
