High-concentration slurry compatible type
Knife edge seal
Cassette seal of static seal structure
Since it is configured as a cartridge, the seal can be installed in equipment in four steps.
To prevent slurry from adhering to the operating O-ring and to ensure that the seal follows the seal ring, this cassette seal uses an operating packing made of special soft rubber (shield O-ring), in addition to the SiCvs knife edge and SiC sliding material. It can be used for higher concentration slurry services.
* With the knife edge structure, this seal can be considered for use even in non-flushing condition. There is limitation in non-flushing application range. For details, please contact us.
