Their performance is on par with international brands, making them a reliable alternative to imported seals.
✅ Core Product Advantages
▶ Highly corrosion- and wear-resistant: The sealing ring is made of pressureless-sintered silicon carbide (SSIC), with a substrate of duplex stainless steels such as 316L and 2205, providing excellent resistance to erosion and corrosion from gypsum slurry and chloride ions.
▶ High impact resistance and reliability: Optimized for slurry pump operating conditions, it can withstand particle impacts and pressure fluctuations, significantly improving the mean time between failures (MTBF).
▶ Long service life with low leakage: Precision end-face grinding plus a compensation mechanism ensure extremely low leakage, effectively reducing the frequency of maintenance downtime.
▶ High efficiency and energy savings: The pump body is designed in accordance with two-phase flow theory and has obtained energy-saving certification, ensuring superior operational efficiency.
▶ High-quality, specialized material: Utilizing the self-developed SL21A material, which offers superior corrosion and wear resistance compared to conventional materials such as Cr30A and 2605N.
✅ Structural features
▶ Single-end face modular design: Fully pre-assembled and molded for easy installation, reducing on-site adjustment errors and enhancing sealing consistency.
▶ External spring isolation: The spring assembly is positioned on the outside of the medium, completely isolating it from corrosive slurries, preventing blockages and corrosion, and extending the service life of the elastic components.
▶ Axial compensation of the stationary ring: The stationary ring features axial floating capability, automatically adapting to axial displacement and thermal expansion to maintain stable end-face contact.
▶ Compact internal structure: Designed to fit the inner diameters of agitator and pump shafts, featuring a compact design and compatibility with standard flange interfaces.
✅ Applicable scenarios
▶ Power plant desulfurization: Side-mounted agitators for absorption towers, slurry circulation pumps, and gypsum slurry pumps—suitable for media with high solid content;
▶ Chemical industry: Sealing for agitator tanks in strong acid and strong alkali environments, suitable for processes involving sulfuric acid, hydrochloric acid, chlor-alkali, and similar substances;
▶ Pharmaceutical biotechnology: Non-sterile reaction system that meets CIP cleaning requirements and prevents cross-contamination;
▶ Environmental Protection Sector: In the paper-making and wastewater treatment industries, suitable for pumps and mixing equipment designed to handle high-fiber and high-viscosity media.
🔥 The Optimal Solution for Domestic Desulfurization Sealing
✅ Selection and Application Recommendations
▶ Key selection criteria: Precisely match the pump model, shaft diameter, medium characteristics (solids content, acidity/alkalinity), and operating parameters (pressure, temperature).
▶ Installation highlights: Ensure the mounting surface is clean and properly aligned. Never force installation to avoid damaging the sealing surfaces.
▶ Maintenance and upkeep: Regularly inspect operating conditions and leakage levels, and promptly replace worn parts to ensure stable equipment operation.
