Containment Seal API682 4th Edition

Pillar RRG mechanical seal is used as secondary seal in tandem seal. Groove on the seal face reduces load to the seal and contributes longer life. Since the seal ring is grooved for reduction of load and is impregnated with special lubricant, it can assure the stabilized sealing performance for a long time. Features Environment…

Mixer & Agitator Mechanical Seal

Pillar “CHEMI-MIGHTY-II” type EAB is a general-purpose type dry contact seal for agitator, in which the stationary seat and shaft packing use the fluorine rubber O-ring having excellent heat and chemical resistance. Since this seal does not require such sealant supply unit like in double seal, it is possible to reduce the equipment cost. *The…

Cassette Seal

Pillar cassette seal type GAKEM adopted the knife edge seal(*1) to the seal surface, which reduce the power consumption, making it possible to reduce the running cost. Pillar cassette seal is applicable to a wide range of fluids from fresh water to chemical fluid and slurry liquid. Pillar cassette seal will not require any experience…

Heavy Duty Seal

Type JAB and YAB seal is for high load condition, which assures the stabilized sealing performance under high-temperature/high-pressure with high velocity and great pressure fluctuation condition. Since bilaterally symmetric floating ring is used, this mechanical seal is resistible against the pressure fluctuation and is so designed that the frictional heat is removed effectively by the…

Split Seal (AR II)

The Pillar type ARII seal adopts special carbon having excellent lubricity make it possible for the pump to perform the dry operation (preceding stand-by operation). Consequently, it is possible to simplify the accessories, no need of flushing and water injection. Splitting the consumable parts make it possible to improve the maintainability. Features Applicable dry operation…

G1 Seal
