MOR 5840 Cartridge Slurry Seal is a cartridge seal design, suitable for abrasive slurry duties and capable of operating without a quench. A modular construction incorporates a cone spring which avoids clogging and eliminates the dynamic O-ring and risk of hang-up. Seal faces are silicon or tungsten carbide and identical. Adaptive hardware is alloyed stainless steel or high chrome iron to provide both excellent corrosion and abrasive resistance of wetted components. A quench seal option is available to improve service life.
Product Features & Benefits
Double-Spring Balanced Design: Adopts a hydraulically balanced structure paired with dual high-strength stainless steel springs, ensuring uniform and stable loading on the sealing face. This design effectively reduces specific pressure, minimizes friction and wear, and maintains stable sealing performance even under fluctuating pressure and temperature conditions, significantly extending the seal's service life.
Strong Abrasion & Corrosion Resistance: The sealing faces are made of high-hardness materials (such as silicon carbide and tungsten carbide) with precision lapping, featuring excellent abrasion resistance. The metal components and secondary seals adopt corrosion-resistant materials, adapting to a wide range of media including corrosive chemicals, abrasive slurries, oil, and high-temperature fluids.
Robust & Stable Structure: The integrated structural design enhances overall rigidity and stability, effectively resisting vibration and shaft deflection during equipment operation. It avoids seal failure caused by mechanical stress, ensuring reliable performance in heavy-duty working scenarios.
Easy Installation & Interchangeability: Compact and standardized dimensions, with clear positioning marks, enabling quick on-site assembly and disassembly. It is fully interchangeable with standard mechanical seal models of the same specification, reducing maintenance time and operational difficulty.
Low Leakage & Environmental Compliance: Optimized sealing face geometry and strict quality control ensure ultra-low leakage (≤0.03ml/min under standard conditions), meeting international environmental protection and industrial safety standards, suitable for occasions with strict leakage requirements.
Application Scope
Widely applied in petroleum refining, petrochemical, chemical engineering, power generation, mining, metallurgy, and water treatment industries. It is particularly suitable for centrifugal pumps, chemical pumps, slurry pumps, oil pumps, and other rotating equipment operating under high pressure, high temperature, or abrasive media conditions, providing reliable sealing protection for continuous industrial production.
