Cost-effective Cartridge Slurry Seal – Type 5840
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.
Product Description Type 5840
Type 5840 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 available of improve service life
