Model Number Breakdown:

65QV → Series name (65mm nominal inlet size, heavy-duty slurry pump design).
SP → Likely indicates "Standard Performance" or a specific variant (could also refer to sealing type or material).
250 → Impeller diameter (250mm) – affects flow rate and pressure.
25 → Design head (25 meters) at the best efficiency point (BEP).

(Note: Naming conventions vary by manufacturer. Verify with supplier documentation.)

Key Features & Design:

Robust Construction:

Materials: High-chrome alloy (A05, A49), rubber lining, or Ni-Hard for extreme wear resistance.

Wet Parts: Replaceable liners, impellers, and throat bushes for extended service life.

Efficient Hydraulics:

Optimized impeller and volute design for abrasive slurries.

Handles high solids concentration without clogging.

Sealing Options:

Expeller Seal (for moderate abrasives, no external water needed).

Mechanical Seal (for fine slurries, requires clean flush water).

Packing Gland (traditional, low-cost option).

Maintenance-Friendly:

Back Pull-Out Design: Allows servicing without disconnecting pipelines.

Heavy-Duty Bearings: Grease or oil-lubricated for long life.

Typical Applications:

✔ Mining & Mineral Processing (tailings, ore transport, coal slurry).
✔ Dredging & Sand/Gravel (river dredging, sand pumping).
✔ Power Plants (ash handling, FGD systems).
✔ Industrial Waste (chemical sludge, wastewater with solids).
