The single cartridge seal is designed to provide low emissions/leakage for most refinery applications. It is applied in Non-Hydrocarbon, Non-Flashing Hydrocarbon, and Flashing Hydrocarbon services. Process leakage is further contained.
API 682 Qualified Single Cartridge Type 1648
The single cartridge seal is designed to provide low emissions/leakage for most refinery applications. It is applied in Non-Hydrocarbon, Non-Flashing Hydrocarbon, and Flashing Hydrocarbon services. Process leakage is further contained.

The 1670's design greatly simplifies installation and maintenance and provides positive protection against seal failure due to faulty mounting. The advance design of bellows seals solves a number of problems that difficult products can pose.

The John Crane Type 2800EH is a noncontacting dual seal for non-turbo smallbore rotating equipment applications, meeting the requirements of standards such as ISO3069C and DIN 24960.
Externally Mounted, Gas Lubricated, Non-contacting Cartridge Double Seal For Pumps
The John Crane Type 2800EH is a noncontacting dual seal for non-turbo smallbore rotating equipment applications, meeting the requirements of standards such as ISO3069C and DIN 24960.

The patented technology and tolerant design, make these seals ideally suited for applications requiring specially engineered seals with performance even beyond that of the standard range.
Non-contacting gas lubricated dual cartridge seal for large bore pumps
The patented technology and tolerant design, make these seals ideally suited for applications requiring specially engineered seals with performance even beyond that of the standard range.

As the worldwide leader in spiral groove technology, John Crane is the first to utilize non-contacting seals in cryogenic applications. John Crane spiral grooves enable the seal to operate on a gas film by gathering and compressing the vaporized liquid.
