4x3D-AH Slurry Pump is a standard horizontal dewatering pump for pumping abrasive slurries, designed for ultra heavy duty applications such as mill discharge, process plant and tailings, high pressure pipelines, as well as other specialty applications.
Bearing assembly use cylindrical structure, which helps adjust the space between impeller and cover plate liner easily, and being removed completely when being repaired. Bearings use grease lubrication. The shaft seal could use the packing seal, centrifugal seal and mechanical seal. The discharge side can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications. Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices. Wide performance, good NPSH and high efficiency, the pump of this type may be installed in multistage series to meet the delivery for long distance.

Tobee® 4X3D-AH Slurry Pumps Design Features:
The 4/3 D AH Slurry pumps are widely used in industry of mining, electrical power, metallurgy, coal, environmental protection, etc for transportation of abrasive solid slurry.
√ Mining & Mineral Processing (Gold/Copper/Iron Ore/Lead & Zinc/Tin/Wolfram etc.)
√ Environmental Water & Sewage Treatment
√ Power & Oil (Bottom ash, lime slurry for FGD)
√ Chemical Industry (Phosphate/Potash/Chemical Fertilizer etc.)
√ Food and Other Industry (Sugar/Paper & Pulp/Tobacco)
√ Dredging (Sand & Gravel)
Tobee® 4X3D-AH 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.
Tobee® 4X3D-AH Slurry Pumps Applications:
AH Series slurry pumps can be used in various of applications, like Minerals processing, Pipeline transport, High velocity hydraulic transport, Coal prep, 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.
