Closed Circuit Pump with Piston Motor (Reversible)

  • Danfoss offers a wide range of efficient fan drive systems. Below are the benefits and critical considerations you need to take into account as you determine the right system for your specific needs.


    • Increased efficiency due to variable flow piston pump
    • Reversibility inherent to the system with no additional plumbing
    • Has inherent zero-speed capability
    • Negligible risk of motor cavitation
    • Well known, closed-circuit technology for high-power applications
    • Higher pump and motor pressure, power and life ratings
    • Fan speed independent of engine speed
    • Minimal reservoir requirements
    • Motor speed sensors available

    Critical considerations:

    • Charge flow required
    • Higher pump and motor cost
    • Motor thrust load capability must be calculated
    • Fan fails to minimum fan speed
