HAH Series Heavy Duty Slurry Pumps China Factory and Leading Suppliers
The HAH series Heavy Duty Slurry Pumps are precision-engineered for the continuous transportation of highly abrasive and dense slurries. Specifically designed to withstand the most demanding environments in mineral processing plants, these pumps excel in critical applications ranging from hydrocyclone feed to flotation and tailings management, ensuring maximum operational stability and systemic efficiency.
Featuring a robust horizontal double-casing axial suction centrifugal design, the HAH series utilizes a ductile iron fully lined casing for superior durability and safety. With customizable wetted pump ends available in high chrome alloy or rubber, these pumps provide a high-pressure, adaptable solution for the most challenging industrial slurry requirements across the global mining and metallurgy sectors.

Frequently Asked Questions
Q: What is the main difference between HAH and HH series pumps?
While both are heavy-duty, the HH series is specifically designed for higher-density slurry applications and can operate under significantly higher pressure conditions than the HAH series.
Q: Which liner material should I choose: High Chrome Alloy or Rubber?
High chrome alloy is recommended for sharp, highly abrasive particles, while rubber lining is ideal for softer, abrasive slurries and provides excellent corrosion resistance.
Q: Can the outlet direction be changed after installation?
The pump is designed to allow the outlet to be positioned in 8 different directions (every 45°) during setup to fit your specific plant layout perfectly.
Q: What industries are HAH series pumps typically used in?
They are widely used in mineral processing, metallurgy, coal power plants, and nonferrous mine tailings management.
Q: How do I maintain the bearings in these slurry pumps?
The HAH series offers both grease and oil lubrication options. Regular lubrication according to the manual ensures minimal friction and extends bearing life.
Q: Are OEM spare parts available for the HAH series?
Yes, we provide a full range of OEM spare parts, including volute liners, throat bushes, frame plate liner inserts, and impellers to maintain peak performance.
