Danfoss 90 Series Piston Pump | 90R55, 90R75, 90R100, 90R130 | Closed Circuit Pump

Danfoss 90 Series High-Pressure Closed Circuit Piston Pump

Product Overview: The Sauer-Danfoss 90 Series is the industry benchmark for closed-circuit hydrostatic transmissions. Spanning displacements from 90R42 to 90R250, this series is specifically engineered for demanding mobile equipment drives. The 90 Series pumps feature integrated charge pumps and system relief valves, delivering peak pressures up to 480 Bar within a compact frame. Core models like the 90R055KP1BC80… offer exceptional control precision, ensuring smooth machine maneuverability across complex terrains.

Key Technical Advantages:

• Full Range Displacement Coverage: From compact 90R42 and 90R55, to mainstream 90R75 and 90R100, up to heavy-duty 90R130, 90R180, and 90R250. Meets power requirements for everything from light harvesters to heavy mining machinery.

• Advanced Control Options (KP/KA): Config codes like 90R055KP1BC80R3S1C03GBA454524 utilize high-performance control valves, supporting Electric Displacement Control (EDC) and manual servo control for precise flow output and directional switching.

• Integrated Closed-Loop Design: Built-in charge pumps and high-pressure relief valves simplify hydraulic plumbing, reduce potential leak points, and provide an outstanding power-to-weight ratio.

• Durability in Extreme Conditions: Featuring reinforced swashplate supports and high-performance rotating groups, the 90 Series maintains peak volumetric efficiency and extended service life even under continuous high-pressure and high-temperature operation.
