Product Overview
The Rexroth A11VO75LRDS/10R-NSD12N00-S (Material Number: 2155690) is a high-performance variable displacement axial piston pump engineered by Bosch Rexroth for demanding open-circuit industrial and mobile hydraulic systems. Utilizing a proven swashplate design, this pump delivers precise, load-sensing (LRDS) control with pressure and flow compensation, allowing it to match system demand while minimizing energy loss and heat generation. With a nominal displacement of 75 cm³/rev, the A11VO series is recognized for its high power density, robust through-drive capability, and long service life in continuous-duty applications. The unit is configured for SAE mounting and features a splined drive shaft, making it a direct-fit solution for a wide range of OEM hydraulic power units and mobile machinery.

Engineering Features & Advantages
- Precision Swashplate Performance: The axial piston swashplate design delivers smooth, infinitely variable displacement with high volumetric and mechanical efficiency, ensuring precise flow control across the full operating range.
- LRDS Load-Sensing Control: Integrated load-sensing with pressure and flow compensation automatically adjusts pump output to match actuator demand, reducing throttling losses, heat generation, and overall system energy consumption.
- High Power Density: Compact housing and optimized piston/cylinder geometry provide high pressure capability (up to 350 bar continuous) in a space-efficient package.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened running surfaces and precision-matched components for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including mounting flange, shaft spline, and port configuration.
Typical Industrial Applications
The Rexroth A11VO75LRDS axial piston pump is widely deployed in heavy-duty open-circuit hydraulic systems, including plastic injection molding machines, metallurgical presses and rolling mills, construction and earthmoving equipment (excavators, cranes, loaders), marine deck
