Face and Circumferential Seals
New-SealTM externally-pressurized, porous media gas face seals enable non-contact shaft sealing. New-SealTM shaft seals can be used for sealing liquids, gases, fine powders, or slurries, with an easy path to retrofit. New-SealTM face seals can be designed to serve as a thrust bearing and a seal, simultaneously. A variety of input gases in addition to air can be used – including process gas.
New-SealTM externally-pressurized, porous media gas circumferential seals can provide shaft sealing when thermal growth scenarios are minimal.
New-SealTM circumferential seals can be designed to serve as a radial bearing and a seal. O-rings, mounted on the outside of the housing, position and support the bearing-seal, allowing it to self-align.
Porous media used is made from familiar materials, such as graphite, carbon or silicon carbide that have proven success in rotating equipment for decades.
