Why Choose Sulzer Cartridge Mechanical Seals?
Sulzer Cartridge Seals are fully pre-assembled sealing units designed for fast installation , precise alignment , and consistent performance. By integrating all seal components into a single cartridge , they eliminate the need for complex setting measurements and reduce the risk of installation errors. Ideal for demanding industrial applications , these seals are built to handle high pressures , variable temperatures , and aggressive media while minimizing maintenance downtime.
Key Technical Specifications
Seal Format: Complete cartridge-type mechanical seal for simplified installation
Design: Balanced configuration to reduce face load and heat generation under high pressure
Materials & Build:
Seal faces in silicon carbide , tungsten carbide , or carbon graphite to suit application media
Elastomers available in Viton , EPDM , or FFKM for optimal chemical resistance
Metallic components in stainless steel or high-alloy grades for corrosion resistance
Spring Arrangement: Isolated springs to prevent clogging from solids or viscous fluids
Installation Features: No measurement or axial setting required; supplied with installation clips or spacers for correct positioning
Operating Limits
Shaft Diameter: Typically 25 mm – 150 mm (model dependent)
Pressure Rating: up to 30 bar(g) depending on seal type
Speed: up to 25 m/s
Temperature Range: –20 °C to +200 °C (material dependent)
Typical Applications
Sulzer process and industrial pumps in chemical , petrochemical , and refinery services
Cooling water and circulation pumps in power generation
Slurry and abrasive media handling with hard face combinations
Pumps in water treatment , pulp and paper , and food processing where clean sealing is critical
Additional Features
Pre-set working length ensures repeatable installation accuracy
Cartridge design reduces downtime during seal replacement
Suitable for single , double , or tandem arrangements for varying duty conditions
Can be supplied with integrated flushing , quench , or pressurized barrier systems
Balanced design tolerates pressure reversals and high vibration environments
