Detailed introduction
Key selling points: Specifically designed for chemical processes + highly resistant to corrosion and abrasion + capable of withstanding high temperatures and pressures + low leakage and long service life + modular design for easy installation.
The SEH chemical pump series mechanical seals are specially designed for harsh chemical process environments characterized by high corrosion and high abrasion! They are suitable for demanding operating conditions across multiple industries, offering reliable sealing performance, environmental friendliness, and safety—making them the preferred solution for industrial sealing applications.
✅ Core Advantages
▶ Exceptionally corrosion-resistant: The sealing ring is made of pressureless-sintered silicon carbide (SSIC), and the substrate can be selected from duplex stainless steels such as SUS316L, 2205, and 2507, offering excellent resistance to chloride ions and erosion by gypsum slurries, making it suitable for media with high solid content.
▶ Long service life and low leakage: Optimized end-face mating and compensation mechanisms ensure a longer service life than conventional seals; precision grinding technology achieves low leakage, guaranteeing that the medium remains contained and does not cause contamination.
▶ Customized Materials: We offer customization options for duplex stainless steel substrates such as 2205 and 2507, tailored to meet the requirements of special operating conditions.
✅ Structural features
▶ Single-end face modular design: Fully pre-assembled to minimize installation errors and ensure high sealing consistency.
▶ External spring isolation: Multiple springs are located on the outside of the medium, effectively isolating corrosive slurries, preventing blockage and corrosion, and extending component life.
▶ Static ring compensation: Axial floating compensation that automatically adapts to displacement and thermal expansion, maintaining face-to-face contact.
▶ Compact internal design: Adapts to the inner diameters of agitator and pump shafts, and is compatible with standard flange connections.
✅ Applicable scenarios
▶ Flue gas desulfurization in coal-fired power plants: Specifically designed for side-mounted agitators in absorption towers, suitable for handling high-solids media such as gypsum and lime slurry;
▶ Chemical reactors: Sealing of stirred tanks for strong acids and strong bases, such as in sulfuric acid, hydrochloric acid, and chlor-alkali processes;
▶ Pharmaceutical biology: Non-sterile reaction system that supports CIP cleaning and prevents cross-contamination;
▶ Paper-making wastewater: Pumps and mixing equipment for conveying high-fiber, high-viscosity media.
