MECHANICAL SEALS

Nippon Pillar has provided various types of mechanical seals with secure high gas-tightness
since 1951 when the Company first developed a mechanical seal to prevent the leakage of hazardous fluids. These mechanical seals are applied in a wide range of industries, including petroleum refining, chemical, paper milling, steelmaking, water supply and sewerage, food processing and ship building. Nippon Pillar's mechanical seals are fully compliant with JIS and ISO standards and deliver a stable performance even under the harshest operating conditions.

CHEMICAL PLANT

Type GAKQM Cassette Seal (Outside type)
Features & Benefits
This is cassette type seal providing easy installation. Replacement from gland packing is not required any modification such as ISO and DIN standard pumps. The use of SiC having high degree of hardness allows for use with liquid containing solid particles.
Performance
Pressure: 0.8MPa Temperature:-20~150℃ Size: 20~100 Application: Oil, Water (max solid particles concentration: 5wt%)
Type GAKQM

Type TELBM SiC xSeal®
Features & Benefits
For fluid containing particles
This seal is multi spring type seal with solid SiC seal ring and radial
grooves on the drive collar. SUS316 is used for metal parts which is applicable to acid, alkaline and wide range liquid.
Performance
Pressure: 0.5MPa (SiC vs SiC), 0.8MPa (S iC vs Carbon)
Velocity: 1 Om/s, Size : $20-55, Application: Slurry pump
Code: MS-TELBM-TI J61 - (Size)

Type WC860 Chemi-Mighty Seal
Features & Benefitsspan>
Contact seal for mixer
This is outside mounted mechanical sea l which uses PTFE bellows and SiC as mating ring So th is type has excellent chemical resistance. Chemimighty seal can be mounted on ceramic or glass lining sleeve.
Performance
Pressure: 0.6MPa, Velocity: 14m/s, Size: <t>20-1 00
Application: Chemical solution, High viscosity liquid, Slurry
Code: MS-WC860-TF022- (Size), SiC vs SiC & PTFE, 316 SS

Type QAKEM Cassette Seal® (Knife Edge)
Features & Benefits
Easy installation
This is cassette type seal providing easy installation. Replacement from gland packing is not required any modification.Since this seal uses knife edge mating ring, it provides the stable performance against high viscous or slurry liquid.
Performance
Pressure: 1, OMPa, Temperature: -20-150"C,
Size: <1>20-100
Application: High viscous liquid, Polymeric liquid
Code: MS-GAKEM-TF022- (Size), SiC vs SiC & Fluoro Elaslomer, 316 SS

Type PEC® Hydrostatic dry gas seal
Features & Benefits
Suitable tor environmental regulation,
pharmaceutical and biochemical industries

The barrier gas is supplied into the grooves on the seal face from outside through the orifices and the opening force lifts off the seal faces to non-contact state. The seal gas consumption from narrow gap is small and process gas is sealed hermetically.
[Palen] Pending US, EP, KR , CN TW, BR, URI
