TBC

Summary

Product identification

The GIW® TBC is a high-head and high-flow pump designed for hydraulic transport applications. These are horizontal end suction centrifugal pumps built for maximum resistance to solids and capable of withstanding very high pressures.

Operating limits

• Discharge: 18 to 30 in (450 to 760 mm)
• Flow rates: up to 80,000 gpm (18,200 m³/h)
• Total head: up to 300 ft (90 m)
• Pressure rating: up to 533 psi (up to 37 bar)
• Power rating: 10,000 hp (7450 kW)

Feed water

The pumps are designed for severe duties involving hydraulic transport of highly abrasive slurries, including:

• Oil sands
• Ore and mineral tailings
• Solids passage capability is optimized through computer-designed shell and impeller hydraulics.

Electrical

• Power rating: 10,000 hp (7450 kW)

Mechanical / hydraulic

Design Features:

• Wear Parts:
  • Slurry Diverter: Increases suction liner life by reducing particle recirculation.
  • Impeller: Designed for wear-resistant operation in highly abrasive slurries, with heavy section clearing vanes to keep solids out of the nose gap.
  • Replaceable Suction Liner: Facilitates internal inspection and minimizes wear part costs; can be rotated for extended life.
  • Pump shell: "Tie Bolt Construction" design for safety and reliability in high-pressure applications.
• Efficiency:
  • Lower Specific Speed Design: Large diameter impeller allows slower operation for better wear life and a wide range of flow conditions.
• Maintenance Friendly:
  • Impeller Release Ring: Standard on all TBC pumps, a 3-piece segmented ring mounted between shaft sleeve and shaft shoulder, drastically reducing wet end change-out time.
  • 2-piece suction plate design: For TBC 54 and larger pumps, an inner "Front Door" suction plate allows replacement of the suction liner and impeller without removing the outer suction plate.
• Reliability in Design:
  • Pressure load against the shell is transferred to non-wearing side plates, held by large tie bolts.
  • Shell and impeller hydraulics are computer-designed to optimize performance and wear, providing high suction capability and large solids passage.
• Materials:
  • Constructed of abrasion-resistant white irons, ductile irons, and special alloys.
  • Alternative wear liner materials: urethane and neoprene.
• Shaft Seals: TBC shaft seals, SpiralTrac™.
• Interchangeability: Various hydraulic design and material options can be used on the same mechanical end, allowing for easy modification to changing conditions.
