Type 5840

Cost-effective Cartridge Slurry Seal

Our Type 5840 single-cartridge seal encompasses many of the advantages associated with heavy-duty seal design, encased in a cost-effective package. Designed for the volume requirements associated with general mining processing duties, it contains robust primary and secondary seal face materials, making it the perfect general-purpose seal for slurry applications.

Features

• Non-clogging, elastomer-encased cone spring applies constant spring load, eliminating dynamic O-rings.
• Hydraulically balanced design with no sliding O-rings to cause hang-up.
• Operates without flush, removing the need for circulation plans.
• Operates with or without water quench.
• Cartridge configuration allows for ease of installation.
• Standard materials specified to meet the requirements of many duties; alternatives available where required.
• Fully interchangeable with many designs already installed in the field.
