A10VSO45 Hydraulic Pump for Rexroth A10VSO18 A10VSO28 A10VSO71 A10VSO100 A10VSO140

A10VSO Series — Rexroth-Compatible Industrial Variable Displacement Axial Piston Pump

H-STAR A10VSO Series is a premium aftermarket replacement for Bosch Rexroth A10VSO Series 31 axial piston variable displacement pumps. Designed for industrial open-circuit hydraulic systems, it features a swash-plate design with 9 pistons, delivering reliable performance at 280 bar nominal pressure (350 bar peak).

Engineered to Rexroth original specifications, the H-STAR A10VSO uses the same rotary group geometry, port plate design, and control mechanism interface. Every critical dimension — mounting flange, shaft extension, port locations, bolt pattern — matches the Rexroth original, ensuring drop-in replacement without any modification to your existing system.

Key Advantages:
* Rexroth-compatible dimensions: bolt-on replacement, no piping or coupling changes needed
* ISO mounting flange + keyed shaft: standard industrial interface (DIN 6885)
* Low noise design: optimized port plate reduces pulsation and mechanical noise
* 10 control options: DR, DRG, DFR, DFR1, DFLR, DG, FHD, FE1, DFE1, ED
* 100% through-drive: mount a second pump (same size) for multi-circuit systems
* 9-piston design: odd number reduces flow pulsation for smoother operation
* Two drain ports: excellent suction performance and case drainage
