Danfoss 42 Series Pump | 42R28, 42R41, 42R51 | Closed Circuit Hydrostatic Pump

Danfoss 42 Series Medium-Duty Closed Circuit Axial Piston Pump

Product Overview: The Danfoss (formerly Sauer-Danfoss) 42 series is an advanced hydrostatic pump range engineered for medium-power Closed Circuit systems. This series covers essential displacements from 28cc (42R28) up to 51cc (42R51). Known for its compact architecture and high level of integration, the 42 series features an internal charge pump and versatile valve functions. Whether in the 42R (Clockwise) or 42L (Counter-clockwise) configuration, these pumps deliver superior power density, making them the ideal power source for compact mobile equipment and industrial drives.

Key Technical Advantages:

• Standard for Medium-Duty Systems: Engineered for reliable performance in medium-load duty cycles. Rated at 310 Bar (4500 PSI) with peak capabilities reaching 415 Bar (6000 PSI).

• Versatile Intelligent Controls (DE):

  • Electronic Control (42R41DE): Models like the 42R41DE1A feature Electronic Displacement Control (EDC), allowing for rapid response and smooth modulation, perfectly suited for modern digital BUS control systems.

• Highly Compact Integrated Design: The pump housing integrates check valves, relief valves, and charge functions within a single unit, significantly reducing plumbing space and minimizing the risk of system leaks.

• High Responsiveness & Durability: Reinforced rotating groups and precision balancing mechanisms ensure stable volumetric efficiency during frequent reversals and speed changes, extending service intervals.
