- Speeds shown are no-load speeds (free-hanging condition).
- Speeds under actual drilling conditions (varying loads) may be 10-15% lower.
- Maximum torque requires a power unit capable of 6,500 psi (450 bar).
- Maximum speed requires a power unit capable of 106 gpm (400 lpm).
- Maximum power means cannot run at maximum torque and maximum speed at same time.
