Hastelloy C alloy centrifugal mining slurry pumps

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 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 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.

14. FAQ 

Faults	Reason	Removal
Pump fails to discharge any liquid.	Incorrect direction of pump rotation and impeller worn. Suction pipe blocked	Check direction of rotation and replace a new impeller
Power consumption on shaft is excessive	Rotating component is rubbing on a stationary part. Bearing worn. Drive belt tension too tight Flow rate too large Pump speed and ratio too high. Misalignment or unparallel of drive shaft and pump shaft.	Removal the rub Replace the bearing Adjust belt Modify the pump duty and speed. Adjust drive and pump shaft
Bearing is over hearing	Lubricants too much or less. Containing impurities in the lubricant Bearing worn.	Lubricating as requirements. Replace clean lubricant. Replace new bearing.
Bearing has short life.	Misalignment or unparallel of drive and pump motor. Shaft bent. Impeller unbalanced due to wear Foreign object entered into the bearing or insufficient lubrication Incorrect procedure followed in fitting bearings.	Adjusting drive and pump shaft. Replacing shaft. Remove rubbing and replace new impeller Clean the bearing. Replace or refit the bearings.
Pump vibrates or is noisy.	Bearings worn. Impeller unbalanced. Air entered into suction pipe or blocked. Flow rate is noneuniform and pump not primed.	Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding.
