About the Lufkin S1800D
Lufkin gear drives are the standard for oil & gas and heavy industrial applications. N-series and S-series parallel shaft units handle the high-torque, high-reliability demands of pump jacks, compressors, and mill drives. Now part of GE Oil & Gas (Baker Hughes), Lufkin units are built to API standards and are highly rebuildable.
The S1800D is a parallel shaft, triple reduction unit with a rated capacity of 150–450 HP and output torque of 55,000–220,000 ft-lb. Typical operating weight is 2,450–4,498 lbs. Mounting configurations include Foot.
Lufkin units most commonly fail from gear tooth pitting in high-load oilfield applications, bearing fatigue in continuous-duty operations, and seal failure in outdoor oilfield environments.
When your Lufkin S1800D fails, downtime costs mount fast. Our standard rebuild turnaround is 8–14 business days with free freight both directions. Emergency 24–72 hour service is available. We publish pricing before teardown — no surprises.
