The GHD Grease Lubrication High Head Slurry Pump is a premium, heavy-duty engineering solution specifically designed to replace HH series pumps in aggressive, high-pressure environments. Featuring a fully encapsulated all-metal wet-end design, this pump is engineered for maximum durability when handling abrasive slurries in horizontal arrangements, ensuring stable performance under extreme industrial stress.
By optimizing the impeller eye to vane diameter ratio, the GHD series delivers significantly higher head per stage compared to standard HAD or Type WAD pumps. This technical advantage, combined with a robust bearing assembly and specialized grease-lubricated labyrinths, makes it the ideal choice for demanding sectors including alumina refining, copper and iron ore mining, and chemical fertilizer production.
| Design Type | Heavy Duty Encapsulated All-Metal | Lubrication System | Grease Lubricated Labyrinths |
|---|---|---|---|
| Pump Arrangement | Horizontal High Pressure | Bearing Type | Heavy Duty Taper Rollers |
| Shaft Design | Rigid Large Diameter / Short Overhang | Sealing Options | Centrifugal or Stuffing Box |
| Impeller Material | Hard Metal or Moulded Elastomer | Casing Material | Cast or Ductile Iron |
| End Cover Assembly | "-10" (Dash 10) with V-Seals | Replacement Compatibility | Replace HH Series |
The all-metal wet-end and encapsulated design are built to withstand the most aggressive high-pressure slurry applications.
Heavy-duty taper rollers and rigid shafts minimize deflection and vibration, significantly reducing wear and tear.
Unique impeller geometry allows for higher head development per stage than HAD and WAD counterparts.
Wet-end components fit standard mechanical ends without adaptor plates, simplifying parts management.
The "-10" end cover with double piston rings and external flingers prevents contamination and leakage.
Interchangeable hard metal and elastomer liners allow customization based on slurry abrasiveness.
Standardized wet-end fits reduce the need for various adaptor plates in storage.
Convenient adjustment positioning below the bearing housing simplifies maintenance.
Short shaft overhang design natively minimizes vibration for better system health.
Centrifugal seal options eliminate the need for external sealing water in many duties.
Removable bearing cartridges allow for rapid replacement and reduced downtime.
Tapered mating faces in hard metal liners ensure positive alignment during assembly.
| Performance Metric | Standard Slurry Pump | GHD High Head Pump |
|---|---|---|
| Head per Stage | Moderate | Significantly Higher |
| Maintenance Cycle | Frequent (Wear-heavy) | Extended (Heavy Duty) |
| Spare Parts Cost | High (Adaptor required) | Low (Standardized Fit) |
| Operational Stability | Medium Vibration | Ultra-Low Deflection |
| Energy Efficiency | Standard | Optimized for High Head |
The GHD pump features a unique impeller eye to vane diameter ratio, allowing it to develop significantly more head per stage, making it more efficient for high-lift applications.
Yes, by utilizing the centrifugal seal arrangement, the need for external sealing water is eliminated for a large percentage of operational duties.
It is ideal for Alumina, Copper, Iron ore, Gold, Potash, and Bauxite mining, as well as chemical fertilizer and water sewerage utilities.
The "-10" end cover assembly uses grease-lubricated labyrinths combined with V-seals and double piston rings to prevent abrasive particles from entering the bearing housing.
The GHD pump offers interchangeable liners and impellers in either hard metal for extreme abrasion or moulded elastomer for specific slurry types.
Yes, it features a removable bearing cartridge and a conveniently located impeller adjustment mechanism below the bearing housing for rapid servicing.
