Product Description
Danfoss 90 Series Closed Circuit Axial Piston Variable Pump
Product Overview: The Sauer-Danfoss 90 series is one of the most powerful Closed Circuit axial piston variable pumps available today. This series is widely utilized in concrete mixer trucks, heavy-duty rollers, crawler cranes, and various high-performance travel drive systems. Known for its compact envelope and the ability to withstand extreme operating pressures, the 90 series is the premier power source for heavy construction machinery worldwide. From the massive 90L250 to the precision-controlled 90R075, this range delivers unmatched dynamic performance.
Key Technical Advantages:
Versatile Variable Control Logic: Models like the 90R055KP1NN80S3S1D03GBA404024 feature KP manual displacement control, while the 90R075HS1CD80R3C7E03GBA352924 supports advanced hydraulic servo control for ultra-precise machine maneuvers.
Exceptional Power Density: Engineered for high-pressure cycles. With rated operating pressures up to 420 Bar (42 MPa) and peaks of 480 Bar, the 90 series outputs more torque and power than competitors within a smaller installation footprint.
Fully Integrated Closed-Loop System: The pump housing integrates a charge pump and pressure limiting valves, simplifying external plumbing layouts while significantly reducing vehicle weight and potential leakage risks.
Reinforced for Harsh Environments: Featuring heavy-duty bearing supports and precision-lapped piston groups. Even in high-inertia applications like the 90L250, it maintains superior volumetric efficiency and extended service life.
Specific Models & Technical Parameters:
Core Series: 90L250, 90R055, 90R075, 90R100 full range.
Specific Configurations: Supports complex codes like 90R055KP1NN80S3S1D03GBA404024 and 90R075HS1CD80R3C7E03GBA352924.
Displacement Range: 55 cm³/rev to 250 cm³/rev.
Rotation Options: Available in Counter-Clockwise (L) and Clockwise (R) configurations.
Applications: Mixer truck hydraulics, paver drives, heavy drilling rigs, and off-highway vehicles.
