WBC

Summary

Product identification

The GIW® WBC pump is designed for long-distance ore and tailings slurry transport. It features a patented design incorporating hydraulic and wear technologies for heavy-duty, high-pressure applications, particularly in ore transport lines subject to sudden pressure spikes.

Operating limits

• Discharge: 18 to 26 in (450 to 660 mm)
• Flow rates: 70,000 gpm (16,000 m³/h)
• Total head: up to 260 ft (80 m)
• Pressure rating: up to 460 psi (up to 32 bar)

Feed water

The WBC pump is suitable for severe slurries and applications including:

• Phosphate
• Tailings
• Ore slurries
• Hydraulic transport
• Pipeline booster stations

Electrical

• Power rating: 8,000 hp (5960 kW)

Mechanical / hydraulic

Design Features

• Wear Parts
  • Impeller: Designed for larger sphere passage.
  • Replaceable Suction Liner: Facilitates pump internal inspection, minimizes wear part usage costs, and can be rotated at intervals to increase wear life.
  • Pump Shell: Computer designed to optimize wear and efficiency and contain sudden pressure surges.
• Efficiency
  • Lower Specific Speed Design: Large diameter impeller allows the pump to run slower for better parts wear life. This design also provides the ability to operate over a wide range of flows.
  • Superior Suction Performance: Designed for excellent Net Positive Suction Head Required (NPSHR) capabilities.
• Maintenance Friendly
  • Impeller Release Ring: Standard on all WBC pumps, this three-piece segmented ring is mounted between the shaft sleeve and shaft shoulder, providing for easy impeller removal and drastically reducing time for wet end change-outs.
• Mechanical End
  • Robust stiffened shaft improves wear life.
  • Split-cartridge bearing assembly with Labyrinth seals protects the shaft and bearings.
  • Heavy duty radial bearings are self-aligning.
  • Limited end float design greatly reduces shaft movement.
• Reliability in Design
  • The pump shell is designed to virtually eliminate bending moments and stresses that cause structural failure during a pressure surge.
  • Non-wearing, ribbed suction and hub plates assist in containing surges, commonly referred to as water hammer.
  • The design is augmented by the use of rugged Gasite® alloys for superior abrasion resistance.
• Other Design Features
  • Minimum Dilution
  • Throat Bushing
  • SpiralTrac™ WBC shaft seals
  • Easy access pedestal
