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. |
MARINE SERVICE
Type US-1,2,3 |
Marine Standard Seal |
|
 |
Features & Benefits |
Marine standard seal
This seal is designed to have dimensions meeting the corresponding requirements of standards establi shed by Japanese Marine Equipment Association. In ordor to prevent corrosion by sea water, it is furnished with mating face of plasma flame fusible ceramics. |

Type PMC |
Rotating clutch-type seal |
|
 |
Features & Benefits |
For cargo pump
Since cargo pumps are comparatively large in size, forced driving system
is applied for seal ring drive. |
 |

Type G1 |
Rubber End-face type Seal |
|
 |
Features & Benefits |
Simplified U-shape rubber seal
The mechanical seal of this type is an end face type seal which uses the simplified U-shape rubber. II is designed compactly so that it enable to be installed in small space. Also il provides the excellent follow -up performance against the axial movement. |
 |

|
Type 6521L |
Carbonized fiber packing |
|
 |
Features & Benefits |
For General Pump
This is made of carbonized fiber impregnated with PTFE dispersion, and lattice braided with special lubricant. This has much enhanced performance than our popular type 6501l. This packing can accommodate big pressure fluctuation, so can be used widely in rotating/reciprocating equipment. |
