Specification of Wear Resistant 95% 99.5% Al2O3 Seal Ring Alumina Ceramic

Wear resistant alumina ceramic seal rings solve tough problems. They handle extreme conditions many materials cannot. These rings use aluminum oxide (Al2O3) as the main ingredient. Two common grades exist: 95% Al2O3 and 99.5% Al2O3. The number shows the pure alumina content.

Both grades offer excellent hardness. They resist scratching and surface wear very well. Abrasive particles cause less damage to these rings. This extends the life of equipment parts. Corrosion resistance is another big plus. These rings handle aggressive chemicals reliably. Acids and alkalis don’t easily attack the ceramic surface.

The 99.5% Al2O3 grade performs better in demanding situations. Its higher purity means greater density. This makes it even harder and stronger. It resists wear more effectively over time. The surface finish can be finer too. This creates a better sealing face. Expect less friction and minimal leakage potential. It handles higher pressures and tougher chemicals.

The 95% Al2O3 grade remains a strong choice. It provides very good wear and chemical resistance. Its cost is generally lower. This makes it practical for many industrial uses. It works well in pumps, valves, and mixers. It handles abrasive slurries effectively.

Key specifications matter for selection. Density is important. The 99.5% grade is denser, usually above 3.90 g/cm³. The 95% grade is slightly less dense, around 3.70 g/cm³. Hardness measures surface strength. The 99.5% grade is harder, typically HRA 88 or higher. The 95% grade is slightly less hard, often HRA 85. Flexural strength shows load-bearing ability. The 99.5% grade is stronger, frequently exceeding 350 MPa. The 95% grade is strong too, usually around 300 MPa. Surface roughness affects sealing. Finer finishes are achievable, especially with 99.5% Al2O3.

These rings fit mechanical seals, bearings, and wear parts. They work in chemical processing, mining, and power generation. They handle dirty water, fuels, and many solvents. Choose 99.5% Al2O3 for maximum performance in harsh settings. Choose 95% Al2O3 for excellent performance where cost is a factor.

Applications of Wear Resistant 95% 99.5% Al2O3 Seal Ring Alumina Ceramic

Wear resistant alumina ceramic seal rings offer excellent performance in tough conditions. These rings come in 95% and 99.5% Al2O3 grades. The high alumina content provides extreme hardness. This hardness directly fights abrasive wear. These rings handle aggressive environments very well.

Chemical processing plants use these seals extensively. They seal pumps moving corrosive liquids and slurries. The ceramic resists attack from acids and alkalis. This prevents leaks and frequent seal changes. Plant downtime reduces significantly.

Oil and gas applications demand reliable sealing. These rings work in downhole tools and valves. They withstand high pressures and gritty well fluids. The material doesn’t corrode like metals. Seal life improves dramatically here.

Mining equipment faces constant abrasion. Ceramic seals protect slurry pumps and hydrocyclones. They handle gritty ore mixtures without wearing out fast. Maintenance costs go down. Equipment runs longer.

Water treatment facilities benefit from these seals. They seal pumps moving water with suspended solids. The ceramic tolerates sand and grit. It also resists corrosion from treatment chemicals. Reliability increases.

General industrial pumps need durable seals. Alumina ceramic rings seal against abrasive media like paints or powders. They handle high speeds and pressures. Friction remains low. Heat generation stays manageable. This protects the seal faces.

These rings also work well in mechanical seals. They pair effectively with softer carbon or silicon carbide faces. The hard ceramic surface resists scoring. Seal performance stays consistent longer. Leakage risks decrease.

The key advantage is long service life. Alumina ceramic withstands wear far better than metals or polymers. Replacement frequency drops. This saves money and time. Operations become more efficient.

5 FAQs of Wear Resistant 95% 99.5% Al2O3 Seal Ring Alumina Ceramic

What are alumina ceramic seal rings used for?
These rings seal pumps and machinery in tough conditions. They handle high wear, chemicals, and heat. Common uses include mining pumps, chemical processing equipment, and valves. They stop leaks effectively.

What’s the difference between 95% and 99.5% Al2O3?
The number shows the alumina purity. 99.5% Al2O3 is denser and harder. It wears slower and resists chemicals better. 95% Al2O3 costs less. It works well for many demanding jobs. Choose 99.5% for the toughest wear and corrosion.

How hot can these seal rings get?
Both types handle high temperatures well. 95% Al2O3 rings work up to about 1500°C. 99.5% Al2O3 rings work up to about 1600°C. This makes them good for hot processes.

Are these rings hard to install?
Handle them carefully. Alumina ceramic is very hard but brittle. Avoid sharp impacts or squeezing unevenly during installation. This prevents chipping or cracking. Follow the equipment maker’s instructions.

Do chemicals damage alumina seal rings?
They resist most chemicals very well. Acids and bases rarely attack them. Hydrofluoric acid and strong alkalis at high temperatures can damage them. Check chemical compatibility for your specific fluid.
