The A10VO series is an inclined - disk axial piston variable pump produced by Rexroth of Germany. It is specially designed for open - circuit hydraulic drives and features high pressure, high efficiency, and flexible variable control.

Core characteristics

• Pressure and flow：The rated pressure is 280 bar, and the peak pressure is 350 bar. The flow is proportional to the driving speed and displacement. Stepless variable control can be achieved by adjusting the swash - plate angle.。

• Displacement specifications：Available in10, 28, 45, 60, 63, 85 cc/r, a total of six displacements (some models are extended to 140 cc/r), suitable for different working conditions.。

• Control methods：Supports various forms such as pressure control (DR), remote pressure control (DRG), power control (LA), and electro - proportional control (EP). It has a short response time and can meet the requirements of complex systems.

• Application scenarios

  Widely used in construction machinery (concrete pump trucks, cranes, road rollers), industrial equipment (machine tools, metallurgy, ceramic presses), ship deck machinery, and marine equipment.

• Structural design

  • Inclined - disk structure with SAE/ISO standard mounting flanges. The shaft extension complies with SAE J744.

    The sealing material is FKM fluororubber. The housing drain port should be connected below the minimum oil level of the oil tank.

    The drive shaft can withstand axial and radial loads and supports through - shaft drive (can be combined with a gear pump or a piston pump of the same specification).
