Key Features of ZGB Slurry Pumps
1.Robust Construction
Materials: High-chrome alloy (Cr27, Cr30), rubber lining, or Ni-Hard for extreme wear and corrosion resistance.
Wet Parts: Replaceable impeller, liner, and throat bush for easy maintenance.
2.Efficient Hydraulics
Semi-open or closed impeller design to handle large solids (up to 50mm).
Optimized volute casing for reduced turbulence and wear.
3.Sealing Options
Expeller seal (standard for abrasive slurries).
Mechanical seal (optional for finer slurries).
Packing gland (traditional, low-cost option).
4.Heavy-Duty Bearings
Grease or oil-lubricated bearings for extended service life.
Designed to handle high radial and axial loads.
5.Maintenance-Friendly
Back pull-out design allows servicing without disconnecting pipelines.

Comparison to Other Slurry Pumps
Type ZGB Advantages Limitations AH Series More compact, lower cost Less robust for extreme abrasion QV Series Higher head capabilities More expensive ZGB Series Heavy-duty, long wear life Larger footprint Maintenance Tips
1.Regularly inspect wear parts (impeller, liner) for erosion.
2.Monitor seal performance (leakage indicates wear).
3.Lubricate bearings as per manufacturer guidelines.
