Product Description
Danfoss 90 Series High-Pressure Piston Pumps for Road Rollers
Product Overview: The Danfoss 90 Series is a globally recognized benchmark in hydrostatic transmission technology, delivering exceptional performance in Road Roller, paver, and skid steer loader drive systems. This comprehensive range covers displacements from the compact 55cc (90R055) to the massive 250cc (90R250), including 75cc (90R075), 100cc (90R100), 130cc (90R130), and 180cc (90R180). Featured models like the 90R055 KA1NN80 S4S1 C03 GBA383824 deliver industry-leading performance. With its integrated charge pump and rugged swashplate design, the 90 series pump withstands frequent reversals and long-term vibratory shocks, making it the premier power source for high-performance mobile machinery.
Key Technical Advantages:
Superior Power Density: Delivers working pressures up to 420 Bar within a compact frame, ensuring robust torque for rollers under heavy-load operations.
Versatile Control Modalities: Supports KA (Mechanical Displacement Control), MDC (Manual), and EDC (Electric) 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 layouts.
Integrated Closed-Loop Design: Built-in high-performance charge pumps and relief valves simplify hydraulic plumbing and drastically reduce potential leakage points.
Extreme Durability: Equipped with reinforced bearing groups and hardened piston components, the 90 series is engineered for 24/7 operation in harsh, dusty, and high-temperature job sites.
