Danfoss OMS 80 Motor 151F0200 | OMS BMT Series | Low Speed High Torque Motor

LIC Hydraulic’s OMS Series (compatible with BMT series) represents the high-end tier of Geroler hydraulic motors. The 151F0200 (OMS 80) model utilizes advanced disc-valve technology to deliver smooth, high-torque performance at low speeds. Engineered to withstand high system pressures and significant external shaft loads, the OMS series is the benchmark for reliability in mobile and industrial machinery. We offer 100% drop-in interchangeability with original Danfoss units, backed by 100% dynamic load testing for guaranteed out-of-the-box performance.

Technical Specifications

• Model: OMS 80 (151F0200)

• Displacement: $80.1\text{ cm}^3\text{/rev}$

• Max Pressure (Cont.): $210\text{ bar}$ (3045 psi)

• Max Torque (Cont.): $240\text{ Nm}$

• Max Speed (Cont.): $750\text{ rpm}$

• Max Power: $15\text{ kW}$ (20.1 hp)

• Shaft Options: $32\text{ mm}$ Parallel Keyed or Splined

• Bearings: Tapered Roller Bearings for high radial load capacity.

Key Technical Advantages

• Advanced Geroler Set: The roller-supported gear set minimizes internal friction, leading to a higher startup torque and smoother rotation at low speeds ($<10\text{ rpm}$).

• Disc Valve Technology: Unlike simpler spool valves, the disc valve is hydraulically balanced and wear-compensated, maintaining peak efficiency throughout the motor’s service life.

• Superior Load Capacity: The robust output shaft and large tapered bearings are specifically designed for direct-drive applications, capable of handling heavy radial and axial forces.

• High-Pressure Shaft Seal: Features a reinforced shaft seal that accommodates higher return-line back pressures without the immediate need for a case drain line in most standard applications.

Application Areas

• Agriculture: Header drives for harvesters, feed mixers, and seed drills.

• Municipal Work: Sweeper brush drives, salt spreaders, and snow removal equipment.

• Construction: Compact loader drives, mini-excavator slew motors, and augers.

• Marine & Winches: High-torque winch drives and conveyor systems.

Expert Maintenance Tips

• System Priming: Before high-speed operation, manually fill the motor ports with filtered hydraulic fluid to prevent dry-start wear on the disc valve.

• Drain Line Recommendation: For applications with continuous high back pressure ($>20\text{ bar}$), always connect the external case drain to the tank to maximize seal life and bearing cooling.

• Filtration Standard: To protect the precision-lapped Geroler surfaces, maintain fluid cleanliness at ISO 19/16 or better. Particles are the primary cause of efficiency loss in orbit motors.
