Product Description

Danfoss 42 Series Mid-Pressure Closed Circuit Variable Piston Pump

Product Overview: The Danfoss 42 series (including 42L CCW and 42R CW) is a premier power core engineered for mid-power hydrostatic transmission (HST) systems. Spanning mainstream displacements from 28cc (42R28) to 41cc (42R41), this series is designed for precision and durability. Featured models such as the 42-R-28-D-L7JC and 42R41 DE1A60 integrate a charge pump, high-pressure relief valves, and versatile control options (MDC/EDC), delivering exceptionally smooth and accurate flow output for compact rollers, drilling rigs, and mobile travel drives.

Key Technical Advantages:

  • Fully Integrated Closed-Circuit Design: Built-in charge pump and charge relief valves simplify hydraulic plumbing, enhancing system response time and power density.

  • Precision Control Architectures (-L7JC / DE1A):

    • Manual/Hydraulic Control (MDC/HDC): Offers excellent operator feedback and mechanical stability.

    • Electric Proportional Control (EDC): Allows for remote flow regulation via 12V/24V signals, perfectly suited for intelligent and automated travel drives.

  • Compact High-Pressure Reliability: Rated for continuous operation at 210 Bar with peak capabilities reaching 350 Bar (5075 PSI), providing structural integrity within a lightweight envelope.

  • Noise & Vibration Suppression: Optimized valve plate and swashplate damping technology drastically reduce fluid-borne noise and hydraulic pulsations.

  • 100% OEM-Standard Compatibility (82856):

    • Complex configuration codes (e.g., DE1A602BDG…) ensure that flanges, shafts, charge displacements, and control response times perfectly match original OEM equipment.

Detailed Models & Parameters:

  • Core Series: Danfoss 42 Series.

  • Part Number: 4282856.

  • Representative Models: 42-R-28-D-L7JC-11-A-N-N-A-F-N-Z-34-34-B, 42R41 DE1A602BDG2HNB2525NNNNNNNNN.

  • Displacements: 28.0 cm³/rev, 41.0 cm³/rev.

  • Pressure Ratings: Rated at 210 Bar (3045 PSI) continuous; Peak cycles up to 350 Bar (5075 PSI).

  • Target Equipment: Asphalt Pavers, Vibratory Rollers, Commercial Mowers, Compact Skid Steer Loaders, and Sanitation Vehicles.
