Danfoss 90R Series Pump | 90R055, 90R180, 90L180 | High Pressure Closed Circuit Piston Pump

Danfoss 90 Series High-Pressure Closed Circuit Axial Piston Pumps

Product Overview: The Danfoss 90 Series is the “Industry Standard” in hydrostatic drive technology, renowned for its extreme reliability and ultra-high power density. Designed specifically for closed-circuit applications, the series covers a complete displacement range from the compact 55cc (90R055) to the heavy-duty 180cc (90R180). Featured models include the 90R055DD1NN60P4S1CGBGBA353520 and the 90R180KA5EF80TCC8H03NNN. Equipped with integrated charge pumps and multi-functional control valves, the 90 series handles extreme pressures with ease. It is the premier choice for asphalt pavers, road rollers, concrete mixers, and the travel drives of massive construction machinery.

Key Technical Advantages:

• Superior Power Density: Delivers continuous working pressures up to 420 Bar within a compact frame, ensuring robust power for machines under heavy-load operations.

• Flexible Control Modalities: Supports Manual, Hydraulic, and EDC (Electric Displacement Control) for precise displacement modulation across diverse operating conditions.

• Bi-directional Support: Available in 90R (Clockwise) and 90L (Counter-clockwise) rotations, perfectly catering to various engine couplings and space layout requirements.

• Highly Integrated Valve Blocks: Built-in high-pressure relief valves, charge relief valves, and bypass valves simplify circuit design and drastically reduce system leakage risks.

• Rugged Industrial Engineering: Featuring reinforced swashplates and high-load bearings, the 90 series is built for 24/7 high-intensity construction environments with extended service intervals.
