151B3268 OMV 500 Danfoss Equivalent Hydraulic Motor

Product Overview

The 151B3268 (OMV 500) and 151B2194 (OMVS 800 HD) are high-pressure, low-speed high-torque (LSHT) orbital hydraulic motors engineered for heavy-duty industrial and mobile applications. As a premium drop-in replacement for the Danfoss OMV and OMVS series, our motors represent the pinnacle of fluid power engineering. Every single unit undergoes rigorous 100% simulated operational testing before leaving the factory, guaranteeing absolute interchangeability in dimensions, port sizes, and hydraulic performance. Delivering smooth and consistent torque under severe pressure drops, these motors are the ultimate driving force for your critical machinery.

Key Technical Advantages

• 100% True Interchangeability: Matches Danfoss OMV/OMVS series perfectly in mounting flanges, output shafts, and port threads. Seamlessly integrate it into existing equipment without modifying hydraulic circuits or brackets.

• Advanced Geroler Gear Set: Features a precision-machined Geroler profile with rollers. This reduces mechanical friction and ensures exceptionally high volumetric efficiency, even after prolonged exposure to high operating pressures.

• Heavy-Duty Tapered Roller Bearings: The output shaft is supported by robust tapered roller bearings that can absorb massive radial and axial loads, eliminating the need for external support bearings in direct-drive applications like winches or wheel drives.

• High-Pressure Shaft Seal Design: Utilizing advanced seal compounds and optimized internal check valves, the motor withstands substantial housing pressure. This protects against seal blowouts and ensures long service life during rapid reversing cycles.

Application Areas

• Construction Machinery: Swing drives for excavators, wheel drives for skid steer loaders.

• Agriculture & Forestry: Harvester header drives, forestry grapple rotators, and wood chippers.

• Heavy Industrial Drives: Marine winch drives, large conveyor belt systems, and plastic injection molding machines.

Expert Maintenance Tips

• Optimal Break-in Period: For the first hour of operating a new 151B3268 or 151B2194 motor, limit the system pressure to 30% of its maximum continuous rating. This allows internal friction components to establish a proper hydrodynamic oil film.

• Case Drain Line Utilization: Although equipped with internal check valves, we highly recommend connecting a dedicated case drain line directly to the reservoir in heavy-duty or high-pressure applications. Keep housing pressure strictly below 15 bar to prevent shaft seal failure.

• Fluid Cleanliness Standard: Disc valve motors rely on tight tolerances. Maintain hydraulic fluid cleanliness to a minimum standard of ISO 4406 20/16/13 to prevent premature wear of the commutator valve and Geroler set.
