The HAD Heavy Abrasive Duty Slurry Pump is an engineering masterpiece specifically designed to tackle the most demanding pumping applications. Engineered for high-abrasion, high-density, and erosive slurries, this pump provides a robust replacement for the AH series, ensuring seamless integration and superior performance in the harshest industrial environments.
By combining extra-thick wear sections with a precision-engineered impeller structure, the HAD series guarantees extended operational life and minimal maintenance requirements. Whether handling mill discharges or tailings transportation, the versatile lining options—ranging from hard metals to various rubber compounds—allow for maximum customization to meet specific chemical and abrasive needs.
| Material Options | Hard Metal / Moulded Elastomer (Rubber) | Application Suitability | High Density & Erosive Slurries |
|---|---|---|---|
| Seal Type | Centrifugal Seal / Packed Gland | Bearing Type | Heavy-Duty Roller Bearings |
| Casing Material | Cast Iron or Ductile Iron | Liner Compatibility | Interchangeable Hard Metal & Rubber |
| Shaft Design | Large Diameter Short Overhang | Adjustment System | Convenient Impeller Adjustment |
| Seal Water Arrangement | Low Flow / Full Flow Flush Available | Replacement Standard | Direct Replacement for AH Series |
Extra thick sections at critical wear points ensure prolonged service life even in highly abrasive environments.
Optimized impeller structure and removable bearing cartridges minimize downtime and simplify servicing.
Choice of hard metal or rubber liners allows the pump to handle both abrasive slurries and aggressive chemicals.
Large diameter shafts with short overhangs minimize deflection and vibration for stable operation.
Centrifugal seals eliminate the need for sealing water in many duties, reducing water consumption.
A minimum number of through-bolts and tapered mating faces allow for rapid component replacement.
Efficient tracking of interchangeable liners and impellers to ensure zero downtime.
Planned inspections of the removable bearing cartridge and seal arrangements.
Real-time tracking of liner thickness to optimize replacement cycles.
Monitoring flow rates and pressure levels to maintain optimal pump efficiency.
Simplified procurement of standard AH-replacement components.
Adjusting impeller clearance via the convenient housing position for peak output.
| Feature | Standard Slurry Pumps | HAD Heavy Duty Series |
|---|---|---|
| Wear Life | Moderate | Extended (Extra Thick Sections) |
| Maintenance Frequency | Frequent | Minimum / Optimized |
| Water Consumption | High (External Seal Water) | Low (Centrifugal Seal Option) |
| Component Changeover | Complex | Rapid (Tapered Mating Faces) |
| Operational Stability | Standard | High (Low Vibration Design) |
The HAD series is engineered with interchangeable dimensions and a similar hydraulic profile to the AH series, while enhancing wear resistance and structural durability for heavy-duty applications.
Rubber liners are ideal for chemical handling and fine, abrasive particles, while hard metal liners are recommended for coarse, high-impact slurry and extreme abrasive conditions.
The centrifugal seal eliminates the need for external sealing water in a large percentage of duties, significantly reducing water costs and simplifying the piping installation.
Vibration is minimized through the use of a large diameter shaft with a short overhang, which reduces deflection and ensures a more stable rotation during high-density pumping.
Yes, a convenient impeller adjustment mechanism is provided below the bearing housing, allowing operators to maintain optimal efficiency as the liners wear down.
These pumps are predominantly used in mining for mill discharge, tailings transportation, and in various chemical processing plants handling erosive slurries.
