Danfoss 90 Series High-Pressure Closed Circuit Variable Piston Pumps

Product Overview: The Danfoss 90 Series is a globally recognized performance benchmark in hydrostatic transmission technology. Engineered specifically for closed-circuit systems, this series offers a full range of displacements from the compact 42cc (90R042) to the massive 250cc (90R250). The 100cc (90R100) variant stands as the premier power source for road machinery and drilling equipment. Flagship models like the 90R100HF1NN80R3C7D03GBA424224 deliver industry-leading reliability. With its integrated charge pump and rugged swashplate design, the 90 Series pump withstands extreme continuous pressures and frequent reversals, ensuring smooth travel for 12-22 ton rollers and large pavers in harsh environments.

Key Technical Advantages:

• Superior Power Density: Delivers up to 420 Bar of continuous working pressure within a compact frame, ensuring robust torque for heavy-load climbing or high-viscosity material processing.

• Integrated Closed-Loop Architecture: Built-in high-performance charge pumps and relief valves simplify hydraulic plumbing and drastically reduce potential leak points and maintenance costs.

• Precision Servo Control: Supports various control modalities including HF (Electric Displacement Control) for rapid response, ensuring stepless speed modulation and fluid direction changes.

• Field-Proven Durability: Hardened rotating groups and friction surfaces are engineered for 24/7 operation in dusty, high-temperature, and intense-vibration construction sites.

• Comprehensive Displacement Range: Unified design philosophy across 55cc, 75cc, 100cc, 130cc, and 180cc, facilitating modular selection for OEM manufacturers.
