The HAD Heavy Abrasive Duty Slurry Pump is a high-performance industrial solution engineered for the most demanding pumping applications. Specifically designed to handle high-density, erosive, and highly abrasive slurries, the HAD series replaces the traditional AH models with enhanced durability. Featuring extra-thick sections at critical wear points and an optimized impeller structure, this pump ensures maximum operational efficiency and a significantly extended service life with minimal maintenance requirements.
To provide versatile application support, the HAD pump offers both hard metal and rubber-lined options. The rubber-lined configurations expand its utility to chemical handling and aggressive environments such as mill discharge and tailings transportation. With an advanced interchangeable system and a robust shaft and bearing assembly, the HAD pump minimizes vibration and deflection, delivering unmatched stability in heavy-duty industrial mining and processing operations.

|---|---|---|---|
| Seal Types | Centrifugal Seal / Packed Gland Seal | Bearing Type | Heavy-duty Roller Bearings |
| Casing Material | Cast Iron / Ductile Iron | Impeller Design | Deep Side Sealing Vanes |
| Maintenance | Interchangeable Liner System | Shaft Design | Large Diameter / Short Overhang |
| Replacement for | AH Series Slurry Pumps | Primary Use Case | Mill Discharge & Tailings Transport |
Extra-thick sections at high-wear points and premium hard metal liners ensure long-term durability against erosive materials.
Optimized impeller structure and removable bearing cartridges minimize downtime and simplify routine servicing.
Choose between hard metal for abrasion or various rubber options for chemical and aggressive slurry handling.
A large diameter shaft with a short overhang significantly reduces deflection and operational vibration.
Centrifugal seal options eliminate the need for sealing water, reducing water consumption and operational costs.
Convenient impeller adjustment and simplified through-bolt casing allow for fast component replacement.
Customize your pump with hard metal or specific rubber liners based on slurry acidity and abrasiveness.
Select between centrifugal seals for water-less operation or packed glands for full-flow flush arrangements.
Easy impeller adjustment located below the bearing housing to optimize flow and pressure.
Modular design allows for precise tracking and scheduled replacement of interchangeable wear parts.
Minimum through-bolt requirements ensure fast assembly and disassembly of the casing to the frame.
Removable bearing cartridges allow for off-site maintenance without dismantling the entire pump.
| Feature | Standard AH Pumps | HAD Heavy Duty Series |
|---|---|---|
| Wear Life | Standard | Extended (Extra-Thick Sections) |
| Maintenance Frequency | Moderate | Low (Optimized Structure) |
| Seal Water Cost | Required for Glands | Optional (Centrifugal Seal) |
| Vibration Levels | Standard | Ultra-Low (Large Diameter Shaft) |
| Replacement Speed | Standard | Fast (Interchangeable System) |
The HAD series features extra-thick sections at critical wear points and an improved impeller structure, providing higher durability and longer service life in extreme abrasive conditions compared to standard AH pumps.
Yes, the HAD pump offers various rubber-lined options specifically designed to handle aggressive chemical products and corrosive slurries.
No. A large percentage of HAD pump duties utilize centrifugal seals, which eliminate the need for external sealing water, reducing operational costs.
It utilizes a large diameter shaft with a short overhang to minimize deflection and vibration, supported by heavy-duty roller bearings in a removable cartridge.
The HAD pump features an interchangeable system with tapered mating faces in hard metal liners, allowing for positive alignment and easy removal during replacement.
It is especially fit for aggressive applications such as mill discharge, tailings transportation, and pumping high-density erosive slurries in mining operations.
