The Danfoss 90R Series represents the industry-leading standard for high-pressure, variable displacement axial piston pumps designed explicitly for closed-circuit hydrostatic transmissions (HST). Engineered with a heavy-duty parallel piston configuration and a responsive cradle swashplate, these Right-Hand (Clockwise) rotating pumps feature an integrated charge pump and advanced servo control systems. They deliver unmatched power density, seamless proportional speed control, and flawless forward/reverse reversible flow under severe operating stresses.

We provide precision aftermarket replacement units and comprehensive repair solutions for the full 90R lineup:

  • Medium Displacements: 90R042 / 90R055 / 90R075 (Extremely popular in compact rollers and small drills).

  • Large Displacements: 90R100 / 90R130 / 90R180 / 90R250 (Engineered for high-tonnage concrete mixers, mega winches, and mining equipment).

  • Control Valve Adaptation: Fully configurable to match original MDC (Manual), EDC (Electrical), or HD (Hydraulic) control
    settings.

Application Information:

This ultra-robust variable hydraulic pump series operates as the primary power driver across global industrial fleets:

  • Transit Concrete Mixers: Direct replacement for main drum drive pumps (especially common in 90R075 and 90R100 configurations).

  •  Road Construction Machinery: High-frequency soil compactors, asphalt rollers, and heavy-duty pavers.

  • Heavy Earthmoving & Mining: Undercarriage travel systems for high-tonnage bulldozers, crawlers, and rotary drilling rigs

  •  Agricultural Equipment: Main hydrostatic propulsion drives for large grain harvesters and multi-crop combines.
