Danfoss OMT Series Heavy-Duty LSHT Hydraulic Motors

Product Overview: The Danfoss OMT Series is a high-power orbital hydraulic motor family engineered to handle the most grueling duty cycles. Featuring advanced Disc Valve technology, the OMT series excels in high-pressure environments and complex radial load applications. This category focuses on key models and precise part numbers: OMT400 (151B3002), OMT250 (151B3020), and the maximum displacement OMT500 (151B3005).

Equipped with oversized tapered roller bearings, the OMT series allows for massive radial loads directly on the output shaft. Its rugged construction and superior volumetric efficiency make it the premier choice for construction propulsion drives, heavy-duty hydraulic winches, municipal sweepers, and agricultural machinery.

Key Technical Advantages:

• Disc Valve Technology: An independent valve plate automatically compensates for wear under pressure, maintaining peak efficiency throughout the motor’s lifespan.

• Superior Bearing Architecture: Reinforced output shaft support makes it ideal for direct-drive equipment subject to shock loads.

• High-Pressure Sealing Integrity: Standard high-pressure shaft seals manage system back-pressure spikes efficiently, ensuring long-term reliability.

• 100% OEM Interchangeability:

  • 151B3002 (OMT400): Standard heavy-duty configuration, one of the most in-demand models globally.

  • 151B3020 (OMT250): Offers a balanced combination of speed and torque.

  • 151B3005 (OMT500): The maximum displacement in the OMT series, delivering extreme torque output.
