The National 55164 Seal 9W is a top-performing, heavy-duty, rotary shaft seal designed for various industrial applications that require seal integrity under extreme conditions. This seal is specifically engineered for use in pumps, agitators, compressors, and other rotating equipment. lesser-known details about this seal are as follows:
The 55164 Seal is manufactured with a robust, 9-inch wide (228.6 mm) face dimension, providing excellent sealing efficiency even in large, high-pressure applications. The seal's primary component is made from highly engineered materials, such as carbon ring and chloroprene compression rings held together with premium quality springs, guaranteeing excellent seal compression and essentially eliminating the chance of leakage. Additionally, the Carbon face, made of carbon graphite, ensures compatibility with a wide range of fluids and chemicals, including those with abrasive or corrosive properties.
The 9W Seal features a double O-ring face design. The primary O-ring is located on the stationary side, providing secondary sealing to counteract any radial pressures and preventing seal face distortion. The secondary O-ring, which is located on the rotating side, prevents any extrusion and ensures proper liquids containment. Moreover, the oil wiper lip on the rotating side continuously cleans the seal faces, maintaining bondline integrity and extending seal life expectancy. These design features make the National 55164 Seal a valuable asset for high-performance applications requiring reliable sealing solutions.
Notable technical specifications of the 55164 Seal include:- Operating pressures: Up to 3,000 psi (20.7 MPa)
- Temperature range: From -22 F (-30 C) to 327 F (163 C)
- Face Material: Carbon with Chloroprene rings
- Working fluids: A broad range of chemicals and liquids
- Face dimensions: 9 inches wide (228.6mm)
- Maximum shaft diameter: 3 inches (76.2mm)
Apart from its exceptional sealing performance, the 55164 Seal is also engineered for easy installation and low maintenance requirements. The carbon face design minimizes the amount of graphite wear debris, making this seal suitable for applications with small seal chambers or situations where traditional graphite debris might cause negative impacts. Lastly, the seal can be used in dismantlable designs where ease of access and low maintenance are critical.
To conclude, the National 55164 Seal 9W is a highly-engineered, resilient sealing solution designed to meet the intricate demands of industrial applications. Its wide face dimension, high compression, and material compatibility, combined with its robust design features and ease of installation, make it a versatile product catering to the mining, chemical processing, power generation, and other demanding industries.
