Fracturing

High-strength gearing for frac pumps and pressure-pumping fleets that endure extreme, repeated shock loads.

Built for fracturing

Hydraulic fracturing subjects gearing to some of the most severe shock and pressure cycling in industry. We build heavy-duty spur and helical gears and drive components for frac pumps and pressure-pumping equipment, hardened and finished to survive the extreme, repeated loads of continuous pumping operations.

Challenges we solve

  • Extreme, repeated shock and pressure cycling
  • High-strength gearing for frac pump power ends
  • Fast replacement to keep pumping fleets running
  • Consistent case hardening for long fatigue life
