Danfoss 90 Series Heavy-Duty Closed Circuit Variable Piston Pumps

Product Overview: The Danfoss Series 90 is the global industry standard for high-performance closed-circuit hydraulic drive systems. Specifically engineered to meet the extreme power demands of heavy-duty mobile machinery and industrial drives, this series offers a comprehensive displacement range from the compact 42cc (90R042) and mainstream 55cc (90L055) to the high-capacity 75cc (90R075) and 100cc (90L100). Featured models like the 90L055-KA1AB60 and 90L100-KA1CD60 withstand peak pressures up to 480 Bar. With its compact swashplate design and superior power-to-weight ratio, it is the premier choice for road roller vibration drives, concrete pump travel systems, harvesters, and heavy-duty cranes.

Key Technical Advantages:

• Extreme Reliability: Optimized for high-frequency shock loads and rigorous duty cycles, maintaining stable power output even in extreme environments like high temperatures or altitudes.

• Versatile Control Modalities: Supports KA (Electrical Displacement Control), MDC (Manual Displacement Control), and hydraulic controls, ensuring precise modulation of machine travel and operational movements.

• Ultra-High Pressure Durability: Rated for continuous operation at 420 Bar (6000 PSI), specifically built for the most demanding conditions in construction machinery.

• Optimized Self-Priming & Charging: Features a high-performance integrated charge pump to keep the main loop primed at high RPMs, preventing cavitation and improving system cooling.

• Modular Through-Drive Capability: Supports tandem mounting of a second Series 90 pump or auxiliary pumps, simplifying the layout of complex multi-circuit hydraulic drive systems.
