Danfoss OMV Series Heavy-Duty Orbital Hydraulic Motors

Product Overview: The Danfoss OMV Series represents the most powerful branch of the orbital motor family. As a definitive Low Speed High Torque (LSHT) power component, the OMV series is engineered for extreme loads and continuous high-pressure operations. This featured selection includes core OMV specifications: the standard OMV630 and OMV800, alongside the wheel-mounted OMVW400, covering essential part numbers 151B3130, 151B3309, 151B3121, and 151B3114. Renowned for its massive torque output, the OMV series is the premier choice for heavy conveyors, marine cranes, construction machinery drives, large winches, and agricultural equipment.

Key Technical Advantages:

• Elite Torque Output: Features an advanced geroler gear set design, providing exceptional starting torque and smooth operation even at ultra-low speeds.

• Massive Load Capability: Equipped with oversized tapered roller bearings that can handle significant radial and axial loads directly, eliminating the need for external bearing supports.

• Integrated Valve Technology: The advanced disc valve design minimizes internal leakage and enhances mechanical efficiency throughout the motor’s service life.

• Wheel Mounting Solution (OMVW): The OMVW400 features a short flange design, allowing the motor to be recessed directly into wheel hubs, optimizing space for travel drives.

• Robust Sealing System: Comes standard with a high-pressure shaft seal, allowing operation under high back pressure and offering superior resistance to environmental contaminants.

• Target Applications: Heavy-duty winches, street sweepers, timber processing, marine deck machinery, and hydrostatic transmission systems.
