Product Description
Danfoss MMF Series Compact Fixed Displacement Axial Piston Motors
Product Overview: The Danfoss MMF Series consists of swashplate-design axial piston fixed motors specifically engineered for closed-circuit hydrostatic transmissions. Known for their ultra-compact envelope and robust internal rotating groups, the MMF series delivers consistent and high-efficiency power within limited installation spaces. This category features key sizes MMF025 and MMF044, including precision models like MMF025DAAGABNNN and part number 4443067. These motors are the essential power source for small vibratory rollers, professional mowers, agricultural auxiliary drives, and municipal sweepers.
Key Technical Advantages:
Space-Efficient Design: The compact housing allows for easy integration into mobile equipment with tight chassis footprints.
High-Speed Stability: Optimized valve plate technology ensures low noise levels and high volumetric efficiency even at maximum rotational speeds.
Rugged Reliability: Built for continuous operation in medium-pressure environments, offering superior resistance to vibrations and shock loads.
Versatile Mounting: Supports SAE standard flanges and multiple shaft configurations for seamless integration with existing hydraulic drivetrains.
Target Applications: Mini-roller travel drives, mower blade drives, conveyor power systems, and various auxiliary motors in open/closed-circuit industrial setups.
