Product Description

Danfoss MMV & MMF Series 44cc Closed Circuit Axial Piston Pumps & Motors

Product Overview: The Danfoss MMV and MMF series are highly cost-effective, mid-range core components for hydrostatic drive systems. Specifically engineered for closed-circuit applications, this series features both MMV044 (Variable Pump/Motor) and MMF044 (Fixed Pump/Motor) configurations. Featured models such as MMF044DAFEABNNN and MMF044DAFHABNNN deliver proven reliability. With a versatile 44cc displacement and highly integrated valve blocks, the MMV/MMF series is widely utilized in rotary drilling rig auxiliary winches, asphalt paver crawlers, harvester reel drives, and various construction and agricultural machinery transmissions.

Key Technical Advantages:

  • Compact Closed-Loop Architecture: Highly integrated housing minimizes external plumbing, reducing potential leakage points and saving critical installation space.

  • High-Response Variable Control (MMV): The MMV044D offers precise displacement modulation, optimizing output torque and speed in real-time based on load demand.

  • Stable Fixed Output (MMF): The MMF044D is renowned for its simple structure and high mechanical efficiency, ensuring long-term stability under constant load conditions.

  • Robust Pressure Capability: Rated for continuous operation at 210 Bar (3045 PSI), with strong peak pressure tolerance to handle the frequent shocks typical of heavy machinery.

  • Integrated Multi-function Valves: Built-in high-pressure relief valves and charge check valves simplify circuit design while enhancing overall system safety and reliability.
