Sauer-Danfoss 90 Series Pump | 90R100, 90L042 | 400 Bar Closed Circuit Pump

Sauer-Danfoss 90 Series Closed Circuit Axial Piston Variable Pump

Product Overview: The Sauer-Danfoss 90 series is a recognized standard in the field of Closed Circuit hydrostatic transmissions. Covering displacements from 42cc to 100cc, these pumps are specifically engineered to meet the grueling demands of heavy-duty mobile machinery. Whether in 90R (Right-hand rotation) or 90L (Left-hand rotation) configurations, the series is renowned for its exceptional power density, reliability, and precision control logic, making it the preferred choice for pavers, mixers, and forestry equipment.

Key Technical Advantages:

• Superior High-Pressure Performance: The 90 series is built for extreme duty cycles, supporting a rated pressure of 400 Bar (40 MPa) and peak cycles up to 450 Bar. Reinforced rotating groups maintain peak volumetric efficiency under continuous heavy-duty loading.

• Versatile Displacement Options: * Model 90L042: Delivering 42cm³/rev for medium-duty driving systems.

  • Model 90R100: Delivering 100cm³/rev for massive power requirements in heavy-duty applications.

• Precision Control Integration: Featuring advanced control units (such as L3C mechanical feedback or EC electronic options), these pumps provide exceptionally smooth starts, directional changes, and stepless speed modulation.

• Integrated Closed-Loop Solution: Includes a fully integrated charge pump and multi-functional combination valves (high-pressure and charge relief), drastically reducing external piping, heat generation, and potential leak points.
