Type 5860
Manufacturer: John Crane
Heavy duty Cartridge Slurry Seal
Available as a single or double seal, the Type 5860 is designed to operate in the harshest abrasive slurry environments. Process fluids such as limestone, phosphates, kaolin clay, drilling mud, coarse coal, boiler fly ash, rock salt, rock and sand are no problem for the Type 5860. Unique design features eliminate problems common to sealing mining process fluids, allowing this seal to operate without a flush, thereby reducing the total cost of ownership.
