The Rexroth A4VSO250 series is a swashplate-type axial piston variable displacement pump designed for open circuit (open loop) hydraulic systems. With a nominal displacement of 250 cm³/r, it delivers high flow at pressures up to 350 bar continuous / 400 bar peak. Manufactured in Germany, the A4VSO250 is available in multiple control versions—including constant pressure (DR), pressure & flow compound (DFR), and electro-proportional (EO2)—making it suitable for heavy-duty industrial applications such as hydraulic presses, steel mill drives, marine power units, and large injection molding machines.

No. The A4VSO series is designed exclusively for open circuit (open loop) systems. For closed circuits, use the A4VG or A4VM series.
DR is constant pressure control only. DFR adds flow control via an external pilot signal, allowing both pressure limit and flow demand to be set—ideal for load-sensing and energy-efficient systems.
Yes, selected A4VSO250 variants with through-drive (through shaft) can be tandem-mounted with another A4VSO or a gear pump to build multi-circuit hydraulic power units.
