Danfoss 90 Series Pump | 90L075, 90L100, 90L250 | 480 Bar Closed Circuit Pump

Danfoss 90 Series Heavy-Duty Closed Circuit Axial Piston Pump

Product Overview: The Danfoss (formerly Sauer-Danfoss) 90 series is a globally recognized benchmark for high-performance Closed Circuit hydrostatic transmission systems. This series covers a complete displacement range from 42cc to the ultra-large 250cc (including 055, 075, 100, 130, 180). Engineered for peak performance in heavy-duty applications, the 90 series operates reliably under continuous pressures up to 480 Bar. Whether utilized in road roller travel drives or rotary drill systems, the 90L (Counter-clockwise) and 90R (Clockwise) configurations deliver superior power distribution and system reliability through integrated charge pumps and versatile control options like MB Servo Control.

Key Technical Advantages:

• Summit of Heavy-Duty Systems: Specifically built for demanding 24/7 continuous high-load operations. Rated at 420 Bar (6090 PSI) with peak capabilities reaching 480 Bar (6960 PSI), offering exceptional resistance to aggressive load spikes.

• Versatile Intelligent Controls (GBA):

  • MB Control (90L075MB): Models like the 90L075MB1NN feature advanced manual/hydraulic servo regulation, ensuring smooth and precise tractive effort modulation across complex terrains.

• Highly Integrated Architecture: The pump housing integrates high-capacity charge pumps, high-pressure relief valves (HPRV), and multi-functional control modules, streamlining closed-circuit plumbing while minimizing leakage risks.

• Superior Power-to-Weight Ratio: The compact housing integrates reinforced swashplate supports and high-precision rotating groups, delivering enormous power output within a miniaturized footprint for long-term service in harsh environments.
