AH Horizontal Centrifugal Closed Impeller 100% Compatible and Interchangeable Gold Mining Slurry Pump

Product Description

1. What is a slurry pump?

       

The centrifugal slurry pump utilises the centrifugal force generated by a rotating impeller to impart energy to the slurry in the same manner as clear liquid type centrifugal pumps.

 

Slurry pumps need much wider and heavier impellers to accommodate the passage of large particles. They also be constructed in special materials to withstand the internal wear caused by the solids.

 

 

2. What advantage of AH(R) slurry pump?

 

AH pumps are those of cantilever, horizontal and centrifugal ones, whose shafts can be sealed by packing seals or by centrifugal type seals.

 

The positions of the pump outlet can be positioned at an interval of 45°according to different requirements, so eight different angles can be applied by rotation in installation.

 

AH slurry pumps with good impeller size and design, its ease of maintenance, the type of shaft seal to be used and the choice of the optimum materials withstand wear caused by the abrasive, erosive and often corrosive attack on the materials. They can also be applied Multi-staged in series.

 

 

3. What mainly usage of AH(R) slurry pump

 

Slurry pumps are widely used to transport corrosive/ abrasive and high concentration slurry in many industries. such as Gold, Silver, Iron ore, Tin, Steel, Coal, Titanium, Copper, Mineral sands, Lead and Zinc. Various other industries include Molybdenum, Electric Utilities, Oil Shale, Water & Sewage Utilities, Building areas, Sand & Gravel, Tobacco and Agriculture (hog, poultry, dairy manure).

 

Mining & Minerals, Grinding and screening, Hydrocyclone separation, Magnetic separation, Flotation, Thickening, Filtration, Leaching, solvent extraction and electrowinning, Pelletising, Tailings, Metallurgy, Roasting, Annealing and pickling, Coke quenching, Hot strip milling, Neutralisation, Mud handling and waste treatment
