Rotary Spring Configuration

The LS830 Light Duty Slurry Seal is engineered for a broad range of process equipment operating in mildly abrasive slurry environments. It is particularly suitable for applications such as chemical leaching, extraction, water treatment, and general utility services.

This single, balanced, multi-spring pusher seal features hard-on-hard face combinations (e.g., silicon carbide vs. tungsten carbide), making it capable of handling light slurries containing up to 10% solids by weight. Its rotary spring configuration is protected from direct exposure to the process fluid, preventing clogging and ensuring consistent spring performance even in challenging slurry conditions.

The LS810’s streamlined geometry minimizes erosion zones, which contributes to longer operational life. As a self-contained cartridge seal, it offers simplified installation and ensures concentricity and face alignment—key for reducing wear and ensuring stable sealing performance.

Designed to operate without external flush or water-based cooling, the LS810 eliminates the need for a continuous water supply, helping to significantly reduce water consumption and associated operating costs. This feature is especially valuable in plants seeking sustainable, water-efficient sealing solutions.

It is particularly effective for equipment such as slurry pumps, agitators, and mixers used in the mineral processing, ore handling, and general slurry service industries.

Key Features:

• Hard-Faced Seal Combinations: Abrasion-resistant faces extend service life.
• Available in Metric and Inch Sizes: Facilitates global compatibility across equipment standards.
• Isolated Springs: Protects springs from slurry exposure, preventing clogging and improving reliability.
• Quick Installation & Easy Removal: Cartridge design simplifies maintenance and reduces downtime.
• Single Seal Configuration: Cost-effective and easy to maintain; suitable for light-duty slurry applications.
• Cartridge and Semi-Cartridge Options: Offers flexibility for equipment design and retrofit requirements.
• Bi-Directional Operation: Functions independently of shaft rotation direction, reducing inventory needs.
• Optimized for Light Slurries: Suitable for up to 10% solids concentration and low to moderate slurry abrasiveness.
• Hydraulically Balanced: Reduces face loading, friction, and wear—extending seal life and improving performance.
• Factory-Assembled & Pressure-Tested: Guarantees performance consistency and minimizes field installation errors.
• Water-Saving Design: Helps meet sustainability goals by reducing dependency on process or utility water for seal operation.
• Rotary Spring Arrangement: Compact and effective; ideal for applications where spring exposure to process media is minimized.
• No External Flush or Cooling Water Required: Eliminates product dilution, lowers water usage, and reduces environmental footprint.
• No Flush or Quench Connections Required: Operates reliably without external liquid support, reducing water usage and simplifying piping.
• Multiple Spring Design: Ensures uniform face loading, better compensation for misalignment, and enhanced performance in variable conditions.
