axial piston pump a10vso140dr 31r vpb12n00 bosch rexroth

Core Specifications

• Model Identification: A10VSO140DR/31R-VPB12N00. Each part of the model has a specific meaning: “A10VSO” represents the series of variable displacement axial piston pumps; “140” indicates the nominal displacement of 140 cm³/rev; “DR” stands for the control device (pressure compensator with remote control); “31R” denotes the mounting flange and shaft end according to ISO standards; “VPB12N00” specifies the additional configuration and performance parameters.
• Displacement: Nominal displacement is 140 cm³ per revolution, and the displacement can be continuously adjusted within a certain range to meet the variable flow demand of the hydraulic system.
• Pressure Rating: It can withstand high working pressure, with a maximum operating pressure of up to 350 bar, ensuring stable operation even in harsh working environments with high pressure requirements.
• Control Mode: Equipped with a pressure compensator with remote control (DR control), which can automatically adjust the displacement according to the system pressure change, realizing energy-saving operation and precise pressure control. The remote control function also facilitates centralized control and regulation of the system.
• Mounting and Shaft End: The “31R” configuration adopts the standard ISO mounting flange and shaft end, which has good interchangeability and is convenient for installation and maintenance, compatible with most hydraulic system installations.

Product Features

• High Efficiency and Energy Saving: The optimized axial piston structure and precise flow control design minimize energy loss during operation, improving the overall energy efficiency of the hydraulic system and reducing operating costs.
• Strong Reliability: Adopting high-quality materials and advanced manufacturing processes, the pump has excellent wear resistance, corrosion resistance and fatigue resistance, ensuring long service life and stable operation even in long-term continuous work.
