High-Density Silicon Carbide Mechanical Seal Ring – For Water Pumps & Acidic Liquids

Silicon Carbide Seal Rings Properties

Application of Silicon Carbide Seal Ring

Type 1: Chemical Process Plant Pump Retrofit
Use Case: Replacing PTFE components with sintered SiC seal rings in high-acid pumps. Result: corrosion rate reduced by 43%, seal failure frequency dropped from once every 2 months → once per 11 months.

Type 2: Water Pump Mechanical Shaft Seal (OEM Line)
Use Case: A medium-sized OEM consolidates three-ring suppliers. ADCERAX supplies ±0.02mm flatness matched pair with 2-week lead time. Assembly error/pass rate improved by 17%.

Type 3: Food-Grade Equipment
SiC seal rings are used in non-food-contact rotating shaft systems, where high thermal load is present. Long lifetime and resistance to CIP process chemicals confirmed.

Usage Instructions for SIC Seal Rings

• Install using torque-controlled tools to avoid cracking
• Always pair polished faces with polished
• Store with an interlayer cloth to prevent contact fracture
• Cleaning: ultrasonic + pure distilled water (for chemical equipment); avoid acid dip
• Storage: Low-humidity conditions; avoid stacking heavy metals atop
• Use temperature limit: Standard ≤ 250°C under continuous operation
• Avoid hard impact during transport and installation

1. Q: What is the difference between sintered and recrystallised silicon carbide seal rings?
   A: Sintered SiC has higher density (>3.05 g/cm³) and better corrosion & wear resistance. Recrystallised SiC is more porous and suitable for high-porosity applications, not mechanical sealing.
2. Q: Can you match the mating faces of a rotary and a stationary ring?
   A: Yes. We lap and test all matched pairs to ensure a runout of less than 0.01mm and conformity of the mating surfaces.
3. Q: How is the wear resistance of your SiC seal rings measured?
   A: According to ASTM G99, the ratcheting wear test. Our SiC shows 76% lower volume loss than ceramic fibre composite rings under the same load.
4. Q: Can the sic seal rings work under acidic or alkaline liquids?
   A: Yes. Tested at pH 2.0~pH12.5 chemical media at 85°C for 180 hours. No significant change in mechanical properties occurred.
5. Q: Can we provide our CAD or sample for an exact replica?
   A: Yes, we process custom silicon carbide rings based on CAD, step files, or physical samples for replication.

• ⭐️⭐️⭐️⭐️⭐️
  The performance remains stable under high-temperature conditions, with no deformation or cracking issues, thanks to the ceramic robotic arm we purchased from Adcerax.
