Product Description

Rexroth A10VO & A10VSO Series High-Pressure Variable Piston Pumps

Product Overview: The Rexroth A10V series represents the gold standard in global hydraulic transmission. This lineup features the A10VO (74cc), specifically engineered for mobile applications, and the A10VSO (28cc), optimized for industrial drive systems. Flagship models include the A10VO74DFLR (Part No: R902436775), which integrates pressure, flow, and power control functionalities. Utilizing a proven swashplate design, these pumps provide stepless displacement regulation, automatically optimizing flow distribution based on system demand. They are the premier choice for construction machinery, industrial power units, and high-precision machine tools.

Key Technical Advantages:

  • Multifunctional Control (DFLR/DFR1): Equipped with DFLR (Pressure, Flow, and Power control) and DFR1 (Load Sensing), ensuring that the engine or motor operates within its most efficient range, preventing power overload.

  • Exceptional Energy Efficiency: During standby or low-flow demand cycles, the pump rapidly swivels to minimum displacement, significantly reducing energy consumption and hydraulic oil heat generation.

  • Compact High-Power Architecture: Built with high-strength materials, these pumps deliver a robust 280 Bar rating within a compact frame, ideal for heavy-duty requirements in confined spaces.

  • Low Noise & Pulsation: Optimized 9-piston rotating groups drastically minimize noise levels and pressure ripples, making them suitable for environmentally sensitive indoor facilities.

  • Full Lifecycle Reliability: Critical friction pairs (pistons, cylinder blocks, and valve plates) undergo specialized hardening processes, ensuring an extended service life under continuous, harsh duty cycles.

Detailed Models & Parameters:

  • Core Series: Rexroth A10VO Series / A10VSO Series 31.

  • Model Keywords: A10VO 74, A10VSO 28, DFLR, DFR1.

  • Full Config Codes: A10VO74DFLR/31R-VSC12H00T-S1878, A10VSO28DFR1/31R-PPA12N00.

  • Part Number: R902436775.

  • Displacements: 28 cm³/rev (1.71 in³), 74 cm³/rev (4.52 in³).

  • Pressure Ratings: Rated at 280 Bar (4060 PSI) continuous; Peak capability up to 350 Bar (5100 PSI).

  • Rotation: R (Clockwise/CW).

  • Target Applications: Mobile machinery travel drives, industrial HPUs, injection molding drives, and material handling equipment.
