Rexroth A10VSO & A10VO Series 52 Variable Displacement Piston Pumps

Product Overview: The Rexroth A10VSO/A10VO series is the most versatile range of variable displacement piston pumps for global open-circuit hydraulic systems. As the flagship of the Series 52 platform, these pumps are engineered for compact spaces, high dynamic response, and extended service life. The range features core displacements from the miniature 10cc (A10VSO10) to the mainstream 28cc (A10VO28) and 45cc (A10VO45). Featured models such as the A10VSO10DR/52R (Pressure Control), A10VO28ED72 (Electric Proportional Pressure Control), and A10VO45DFR1 (Load Sensing) deliver unmatched stability. With superior self-priming capability and low operational noise, the A10VSO series is the premier choice for CNC machine tools, plastic processing, mobile auxiliary systems, and compact Hydraulic Power Units (HPU).

Key Technical Advantages:

• Diverse Control Modalities: Offers DR (Pressure Control), DFR1 (Load Sensing), and ED72 (Electronic Proportional), accurately matching power to demand to minimize energy loss.

• Superior Power Density: The Series 52 architecture features a compact frame that provides high rated pressures while significantly reducing the installation footprint.

• Quiet-Series Performance: Optimized swashplate design and valve plate geometry suppress hydraulic ripples, maintaining industry-leading low decibel levels even at full load.

• Extended Durability: Equipped with reinforced bearings and hardened piston groups, ensuring peak volumetric efficiency even under continuous high-pressure cycles.

• Highly Flexible Configuration: Supports various shaft ends (e.g., K68T, PPA14) and seal materials to meet specific industrial protocols and hydraulic fluid requirements.
