Model Number Breakdown (65QV-SPR):

65QV → Series designation (65mm nominal inlet size, heavy-duty slurry pump).
SPR → Likely indicates a specialized variant, possibly:
- "S" – Standard or heavy-duty construction.
- "P" – Particular sealing or material upgrade.
- "R" – Rubber-lined or reinforced design for corrosion/abrasion resistance.
  (Note: Exact meaning varies by manufacturer—check supplier documentation.)

Key Specifications (Estimated):

Parameter	Value
Inlet/Outlet Size	65mm (2.5") / 50–65mm (2–2.5")
Flow Rate	50–130 m³/h (220–575 GPM)
Total Head	15–30m (50–100 ft)
Impeller Diameter	200–300mm (varies by model)
Max. Solids	Up to 60% by weight
Particle Size	Up to 25–40mm (depends on impeller)
Speed	900–1800 RPM
Motor Power	22–75 kW (30–100 HP)
Pressure Rating	Up to 8–10 bar (116–145 psi)

Design & Features:

Robust Construction:
- Materials:
  - High-chrome alloy (A05/A49) for extreme abrasion resistance.
  - Rubber-lined (SPR variant) for corrosive/acidic slurries.
- Replaceable wet parts: Impeller, liner, throat bush for easy maintenance.
Sealing Options:
- Expeller seal (default for slurries with moderate abrasives).
- Mechanical seal (optional, for fine-particle slurries).
- Packing gland (cost-effective, requires periodic adjustment).
Efficient Hydraulics:
- Open or semi-open impeller design to handle large solids.
- Optimized volute casing to reduce wear and improve efficiency.
Maintenance-Friendly:
- Back pull-out design for servicing without pipe disassembly.
- Heavy-duty bearing assembly (grease or oil-lubricated).

Typical Applications:

Mining: Tailings transport, ore processing, coal slurry.
Dredging: Sand, gravel, and silt pumping.
Industrial: Chemical sludge, wastewater with solids, ash handling.
Power Plants: Flue gas desulfurization (FGD) slurry circulation.

Comparison to Similar Models:

Model	Key Difference	Best For
65QV-SPR	Rubber-lined or reinforced design (SPR)	Corrosive + abrasive slurries
65QV-SP	Standard high-chrome alloy	General abrasive slurries
65QV-HS	High-speed variant (2000+ RPM)	High-head applications

Manufacturer Cross-Reference:

Warman (Weir Group): Similar to AH or M series (e.g., Warman 65AH-SPR).
Metso (GIW): Comparable to LSA or LSM series.
Chinese OEMs: Often labeled as 65QV-SPR with similar specs.

Maintenance Tips:

1.Inspect liners/impellers every 500–1000 hours for wear.

2.Monitor seal leakage—replace if slurry bypass exceeds tolerance.

3.Lubricate bearings per manufacturer guidelines (grease/oil type matters).
