- choice of 3 Power Units for maximum performance. Please see spec sheets for variations.
- 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 5,500 psi (380 bar).
- Maximum speed requires a power unit capable of 300 gpm (1135 lpm).
- Max power means cannot run at maximum torque and maximum speed at same time.
