Silicon Carbide Mechanical Seal Rings deliver exceptional performance in the most challenging industrial environments. Engineered for superior durability, they offer high hardness, outstanding wear resistance, and excellent corrosion resistance. These rings are the ideal solution for pumps, compressors, and rotating equipment across chemical processing, marine, and high-temperature applications, ensuring reliable operation and extended service life.
Exceptional Hardness: Provides superior resistance to wear and abrasion.
Outstanding Thermal Stability: Maintains mechanical integrity even at elevated temperatures.
Excellent Chemical Inertness: Highly resistant to corrosion and oxidation.
Low Thermal Expansion: Ensures remarkable dimensional stability during thermal cycling.
Low Friction Coefficient: Offers self-lubricating properties for smooth operation in diverse conditions.
Silicon Carbide (SiC) Product Series & Key Feature:
| Product Code | Type | Process | Key Characteristics |
|
DX101 |
Reaction-Bonded SiC (RBSiC) | Pressed α-SiC powder with additives reacts with molten silicon to form high-density β-SiC. | Density: 3.05–3.10 g/cm³; Free silicon content < 10% |
|
DX201 |
Sintered SiC (SSiC) | Pressureless sintering of fine-grained SiC without free silicon. | High hardness & strength; Excellent oxidation resistance; Suitable for extreme temperatures and strong corrosion. |
|
DX202 |
Sintered SiC + Graphite | Pressureless sintering with fine graphite particles. | Combines SSiC properties with self-lubrication; Resistant to dry friction and wear. |
|
DX203 |
Porous Sintered SiC | Sintering process creates uniform independent spherical micropores. | Micropores store fluid for lubrication, reduce friction and heat; Ideal for low-fluid conditions. |
|
DX204 |
Porous SSiC + Graphite | Integrates graphite particles and spherical micropores. | Resists dry friction and thermal shock; Suitable for severe operating conditions. |
Applications:
Silicon Carbide Mechanical Seal Rings are the preferred choice for sealing applications in pumps and rotating equipment that handle abrasive slurries, corrosive chemicals (including moderate-concentration acids and alkalis), and other demanding environments. Their unique combination of extreme hardness, wear resistance, and self-lubricating properties ensures low maintenance, high reliability, and an extended service life—even under dry-run or marginal lubrication conditions.
