Tobee® TH6x4 Coal Slurry Pumps are designed for handling highly abrasive, high density slurries with excellent wear life while maintaining efficiency during the wear cycle providing the best total operating cost. The coal slurry pumps can be used in many applications, such as Coal prep, Pipeline transport, High velocity hydraulic transport, Mineral processing, Cyclone feeds, Aggregate processing, Fine primary mill grinding, Chemical slurry service, Tailings, secondary grinding, Industrial processing, Pulp and paper, Food processing, Cracking operations, Ash handling etc.
Bearing assembly - A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
Liners - Common material hard metal liners are completely interchangeable with pressure molded elastomer. Elastomer seal rings back all liner joints. Easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintenance.
Impeller - Common material hard metal and molded elastomer impellers are completely interchangeable. Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination.
Throat bush - Common material hard metal and molded elastomer impellers are completely interchangeable. Wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
Pump casing - Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
One-piece frame - A very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.

Tobee® TH6x4 Coal Slurry Pump Structural Design:
Tobee® TH6x4 Coal Slurry Pump Shaft Seal Arrangement:
• Packing Seal is most popular type of seal. Clean water at a certain pressure being injected into the packing through the lantern restrictor, preventing leakage from casing.
• Expeller Seal generates a reverse centrifugal force to prevent the leakage. Suitable for most slurry pumping applications providing a major advantage where no gland water is required.
• Mechanical seal is used for applications where no extra substance is allowed to mix with the fluid being pumped, such as chemical or food industry.
