Danfoss MMF MMV Series Piston Motor | MMF044 MMF035 MMV046 | High Pressure Motor

The Danfoss MMF, MMV, and MMC Series from LIC Hydraulic are high-performance Axial Piston Motors specifically developed for the rigorous demands of the mobile hydraulic market.

• MMF (Fixed Displacement) units provide reliable, constant torque.

• MMV (Variable Displacement) units offer the flexibility of adjustable speed and torque ranges.

• MMC (Integrated Control) units streamline system design by incorporating necessary control valves into the motor housing.

  Featuring the rugged MMF044DAAUABNNN configuration, these motors are synonymous with durability and efficiency. We offer 100% drop-in replacements that guarantee seamless integration with your existing hydrostatic transmissions.

Technical Highlights

• Displacements: $23, 25, 35, 44, 46\text{ cc/rev}$ options.

• Max Pressure: Up to $350\text{ bar}$ ($5075\text{ psi}$) continuous.

• Design: Swashplate axial piston technology for compact footprint.

• Control Options: Manual, Hydraulic, or Electric Proportional (for MMV series).

Core Advantages

• Proven Reliability: Derived from the legendary Sauer-Danfoss engineering, these motors are built to handle millions of cycles in harsh outdoor environments, from freezing agricultural fields to scorching construction sites.

• High Efficiency: Optimized porting and low-friction rotating groups ensure maximum power transfer from the pump to the wheels, reducing fuel consumption.

• Versatile Mounting: Standard SAE flanges and spline options allow for easy installation into a wide variety of gearbox and wheel-hub configurations.

• Integrated Solutions: The ability to include relief and flushing valves directly in the motor (MMC/MMF versions) reduces the number of external hoses and potential leak points.

Expert Maintenance Tips

• Case Flushing is Critical: For high-speed applications, ensure that the case flushing flow is sufficient to keep the internal bearings and seals cool. Overheating is a primary cause of seal hardening and leakage.

• Shaft Seal Protection: When painting or cleaning the machine, avoid direct high-pressure spray onto the shaft seal area. Contaminants forced past the seal can cause internal scoring.

• Air Bleeding: During initial startup, fill the motor case with clean hydraulic oil. Air trapped in the rotating group can cause immediate damage to the piston slippers during the first few seconds of operation.
