Rexroth Axial Piston Variable Pump A15VSO, A15VLO

Bosch Rexroth A15VSO axial piston variable pump

Description:

The Bosch Rexroth A15VSO / A15VLO series are high‑pressure axial‑piston variable displacement pumps, employing a swashplate (cradle) design for hydrostatic drives in open‑circuit hydraulic systems. Flow output is continuously adjustable — proportional to drive shaft speed and swashplate displacement — enabling precise control of hydraulic fluid flow and system pressure. These pumps are engineered for demanding industrial applications, providing high efficiency, compact installation footprint, and robust performance under heavy load.

  • Variable displacement & continuous control: Pump flow can be infinitely varied by adjusting the swashplate angle, allowing fine-tuned flow and pressure control for different tasks.

  • High pressure capacity: Nominal working pressure typically 350 bar, with maximum up to 420 bar — suitable for heavy‑duty hydraulic systems.

  • High efficiency & power density: Overall efficiency up to ~93%, compact design and high power despite relatively small installation space.

  • Flexible configuration & through‑drive option: Optional charge pump (impeller) version (A15VLO) allows higher operating speeds; through‑drive enables combination with other pumps (e.g. gear pumps) for multi‑circuit systems.

  • Low noise & stable operation: Housing optimized for minimal sound emissions; stable displacement delivers smooth flow.

  • Wide application range: Suitable for stationary industrial hydraulics — machine tools, presses, heavy‑duty equipment — wherever variable flow and high pressure are required.
